Quick verdict: The PAKA Original Crew ($149) is the sweater I pull on the second the temperature drops — the cool bite of a summer morning at camp, the chill that rolls in after the sun goes down, and, before long, every crisp fall day I can get. Built from a 65% Royal Alpaca blend, it’s softer than cashmere, absurdly light (under a pound), naturally odor-resistant, and thermoregulating across a wide temperature swing. It’s not cheap, but this is a buy-it-for-a-decade piece. It’s already my favorite layer, and I haven’t even gotten it to aspen season yet.

There’s a particular kind of cold that summer camping sneaks in on you. It’s not the deep cold of winter — it’s the 5 a.m. chill when you unzip the tent, or the drop that comes the moment the sun dips behind the ridge and the fire hasn’t caught yet. It’s the reason I always throw one sweater in the bag no matter how warm the forecast. For a while that was whatever old fleece was closest. Now it’s the PAKA Original Crew, and it’s not close.

What is the PAKA Original Crew?

This is the sweater PAKA was founded on — the piece the whole company grew out of, first knit in Cusco, Peru. It’s their best-seller and their flagship, and unlike a lot of “alpaca-blend” apparel, it’s alpaca-forward. The essentials:

Spec	Detail
Price	$149
Material	65% Royal Alpaca fiber / 35% recycled nylon
Weight	0.89 lb / 14.24 oz
Fit	Unisex, relaxed
Comfort range	Thermoregulating across a 50°F+ range
Construction	Stretch side-panels, raglan sleeves for range of motion
Softness	Royal Alpaca at 18–19 microns — softer than cashmere
Sourcing	Hand-knit and hand-signed by women artisans in Peru; OEKO-TEX certified dyes
Care	Hand wash cold (or machine delicate/cold); lay flat to dry

That 65% Royal Alpaca content is worth pausing on. The PAKA pieces I’ve reviewed before — the Sol Hoodie, the Essential boxer brief — use alpaca as a performance accent in a larger blend. This flips that: alpaca is the main event here, which is why it feels and performs the way it does. At 18–19 microns, the fiber is fine enough to wear with nothing underneath.

Why alpaca makes this the perfect camp layer

I’ve gone deep on alpaca fiber in my other PAKA reviews, so I’ll keep this focused on what matters for a camp sweater specifically.

Thermoregulation across a huge range — this is the headline. Alpaca evolved in the Andes, where a single day swings from below freezing to warm sun, and the fiber adapted to handle both. PAKA pegs the Original Crew’s comfort range at over 50°F. In plain terms: it keeps you warm in the pre-dawn chill and doesn’t cook you when you’re moving around camp or the afternoon warms up. That range is exactly the summer-camping problem — cold mornings, warm middays, cold evenings — solved by one layer you never take off.

It’s shockingly light and packable. At 0.89 lb, it weighs less than your coffee mug. It’s the definition of a no-brainer throw-in-the-bag layer, because it costs you almost nothing in pack weight or space and pays off every single time the temperature dips.

Naturally odor-resistant. Alpaca resists odor-causing bacteria, so this handles the reality of camp life — worn around the fire, slept in, worn again the next morning — and stays fresh far longer than fleece or synthetics between washes. On a multi-day trip that’s not a luxury, it’s the difference between one sweater working for the whole trip and needing a backup.

Softer than cashmere, and no itch. Royal Alpaca is lanolin-free, so there’s none of the scratch people brace for with wool. This is genuinely luxurious against the skin — soft enough that “I’ll wear it to bed in the tent and then to dinner in town” is a real sentence.

On cool camp mornings and evenings

This is where it’s earned its place in my kit this summer.

The morning routine at camp is the best argument for it. Crawl out of the tent into the cold, pull the Crew on over a tee, and stand there with a coffee while the valley warms up — comfortable the entire time, from the shivery first minute to the point where the sun finally clears the ridge. I don’t have to shed it as things warm because the thermoregulation handles the transition. Same story in reverse at night: as the fire dies down and the cold settles in, it’s the layer that keeps the evening going a little longer instead of driving me into the tent.

The relaxed fit, stretch side-panels, and raglan sleeves mean it moves — reaching for firewood, hauling the cooler, scrambling around camp — without binding or riding up. It’s a sweater that works, not just one that looks the part.

The part I’m actually looking forward to: fall

Here’s my honest confession. As good as this has been for summer camping, I bought it with September and October in mind, and I can’t wait.

There’s a specific window in the Colorado high country when the aspens turn — whole hillsides going gold, the air gone crisp, the light turning that low amber color that only happens in fall. It’s my favorite few weeks of the year, and it’s exactly the weather this sweater is built for: cool, dry days where you want one perfect layer from the morning hike through the afternoon leaf-peeping to the cold walk back to the car. I already know the Original Crew is going to live on my back for that entire stretch — trailheads, overlooks, a thermos of something warm, gold leaves overhead. If it’s this good in the margins of summer, fall is going to be its whole season.

Honest notes

The price. $149 is a real number for a sweater. What you’re paying for is 65% Royal Alpaca (not a token blend), genuine hand-knit construction by Peruvian artisans, and the kind of durability that makes this a ten-year piece rather than a two-season one. Cost-per-wear is where it wins — but the upfront sticker is the sticker.

It needs gentle care. Hand wash cold is best; if you machine wash, keep it on delicate and cold, and always lay flat to dry. This is the trade for a natural, fine-micron fiber — it’s not the toss-it-in-on-hot piece a synthetic hoodie is. Treat it right and it lasts; treat it like gym gear and you won’t be happy.

Relaxed, unisex fit. The cut is intentionally relaxed. I love it, but if you want a trim, athletic silhouette, size down or know that’s not this sweater’s personality.

Who it’s for

• Buy it if: you want one do-everything layer for cool mornings and evenings, you camp or travel in variable temps, you value natural fiber and ethical sourcing, and you’ll keep a quality piece for years.
• Skip it if: you want a low-maintenance machine-wash-and-forget layer, or you’re not looking to spend at this tier.

PAKA Original Crew: the verdict

The best layer is the one that quietly solves a problem you’d stopped expecting to solve — in this case, the constant on-and-off of dressing for temperatures that won’t hold still. The PAKA Original Crew handles the whole swing of a camp day in one impossibly soft, sub-one-pound package, and it does it while looking good enough to wear straight into town.

It’s already my most-reached-for layer of the summer, and I have a feeling that once the aspens turn, it’s barely coming off. At $149 it’s an investment, but it’s the kind you feel good about every cold morning you pull it on. That’s the highest compliment I give a piece of gear.

FAQ

Is the PAKA Original Crew good for camping? Yes. Its alpaca fiber thermoregulates across a 50°F+ range, so it keeps you warm on cold camp mornings and evenings without overheating midday. At under a pound it packs easily, and its natural odor resistance means one sweater handles a multi-day trip.

What is the PAKA Original Crew made of? 65% Royal Alpaca fiber and 35% recycled nylon. The Royal Alpaca is 18–19 microns, making it softer than cashmere and itch-free.

How warm is it? PAKA rates its comfort range at more than 50°F thanks to alpaca’s natural thermoregulation — warm when it’s cold, breathable when you’re active. It’s a versatile three-season layer rather than a heavy winter-only sweater.

How much does it weigh? 0.89 lb (14.24 oz) — lighter than a full coffee mug, which makes it an easy layer to pack.

Is alpaca itchy? No. Alpaca is lanolin-free, the compound most people react to in sheep’s wool, so it feels smooth and soft against the skin — you can wear this crew without an undershirt.

How do you wash it? Hand wash on cold for best results, or machine wash on delicate and cold. Always lay flat to dry; do not iron.

How much does it cost? $149, with free shipping on PAKA orders over $150.

Is it good for fall? Ideal. Cool, crisp fall days are squarely in its comfort range, making it a perfect single layer for hikes, leaf-peeping, and everything from morning to evening.

Quick verdict: The PAKA Men’s Essential Boxer Brief ($39) is the best trail underwear I’ve tested, full stop. Built on a Royal Alpaca, TENCEL, and organic Pima cotton blend, it does the two things that actually matter on an extended trip: it resists odor well enough to wear for multiple days between washes, and it wicks and moves well enough that I’ve done big mileage with zero chafing. It’s not cheap for a single pair, but for camping, thru-hiking, and travel, it’s worth every dollar. This is the “forget you’re wearing it” underwear the marketing promises, and for once the marketing is right.

Let’s just get the awkward part out of the way, because there’s no polite way to review trail underwear.

On an extended camping trip, you are not doing laundry. You are wearing the same base layers for days, and the single garment that determines whether that’s tolerable or miserable is your underwear. I know how it sounds. But the honest test of a piece of trail underwear is exactly this: can you wear it for multiple days, put real miles on it, and not end up chafed, swampy, or unbearable to be around? The PAKA passes that test better than anything else I’ve worn, and it comes down to the fiber.

What is the PAKA Essential Boxer Brief?

It’s PAKA’s everyday boxer brief, built from the same alpaca-fiber philosophy the brand is known for, blended specifically for all-day, stay-put comfort. The details:

Spec	Detail
Price	$39 (single pair)
Fabric	48% TENCEL, 33% organic Pima cotton, 14% Royal Alpaca, 5% BPA-free spandex
Style	Boxer brief, jersey knit with fly opening
Properties	Moisture-wicking, fast-drying, odor-proof, antimicrobial, thermoregulating
Fit	Stretchy, shape-retaining, “barely-there”
Sourcing	Traceable Alpaca™; supports 300+ women artisans in Peru
Sustainability	Natural fibers, BPA-free spandex, no forever-chemicals against skin

The blend is the key. Royal Alpaca brings the performance, TENCEL (derived from eucalyptus) adds a cooling, moisture-moving layer, organic Pima cotton keeps it soft and familiar next to skin, and a touch of spandex gives it stretch that snaps back to shape instead of bagging out.

Why alpaca fiber is the secret

If you read my PAKA Sol Hoodie review, you know I went deep on why alpaca outperforms. The same fiber science is doing the heavy lifting here, and in underwear the benefits are even more noticeable because of where and how you’re wearing it.

It’s naturally odor-proof and antimicrobial — this is the whole ballgame. Alpaca fiber naturally resists the bacteria that cause odor. That’s not a coating that washes out; it’s structural to the fiber. In practice, it’s what lets you wear these for multiple days on the trail without them turning into a biohazard. Synthetic underwear holds onto stink after a single sweaty day — the bacteria live in the fabric. Alpaca simply doesn’t give them the same home. It’s the single most important property in a piece of multi-day trail underwear, and it’s the reason these have earned a permanent spot in my pack.

It’s hollow-core, so it thermoregulates and wicks. Alpaca fibers have microscopic air pockets that move moisture and air, pulling sweat away from your skin and letting it evaporate. Paired with the fast-drying TENCEL, that keeps you dry down there — and dry is the entire foundation of a no-chafe day (more on that below).

It’s lanolin-free, so there’s zero itch. The classic knock on wool underwear is that the idea makes you wince. Alpaca has no lanolin, the compound most people actually react to, so it lands closer to cashmere than to scratchy sheep’s wool. Against sensitive skin, all day, that matters a lot.

It covers you in natural fiber, not forever-chemicals. Most performance underwear is pure synthetic, sometimes treated with antimicrobial chemistry that sits against your most absorbent skin. PAKA’s approach is natural fibers doing the work instead, with BPA-free spandex and Traceable Alpaca sourcing. If you’re trying to get petrochemicals off your body, this is a legitimately better option.

Multi-day wear: the honest report

Here’s the part that sounds gross and is actually the point.

On a recent multi-night trip I wore a single pair for the duration — hiking during the day, sleeping in them, back on the trail the next morning. Normally that’s a recipe for regret. With these, it genuinely wasn’t. The odor resistance is real: they stayed wearable and fresh-enough across multiple days in a way synthetics simply don’t. Air them out overnight and they reset noticeably by morning. I’m not going to tell you they’re magic and never need washing — they’re underwear, not sorcery — but the number of days you can comfortably and considerately go between washes is dramatically higher than anything synthetic or plain cotton.

For an extended camping trip where every ounce and every wash counts, that changes your packing math. Two pairs covers a trip that used to need four or five. Less weight, less laundry, more trail.

Thru-hiking and the no-chafe test

The bigger claim, and the one I was most skeptical of: real mileage with no chafing.

Chafing is a moisture-plus-friction problem. It happens when wet fabric drags against skin, mile after mile. Beat the moisture and the smoothness of the fit, and you beat the chafe. These win on both:

• Moisture management. The alpaca-and-TENCEL blend wicks sweat and dries fast, so the fabric against your skin stays dry instead of turning into a wet, abrasive layer. This is the root fix.
• Shape retention. The spandex means they stretch with every stride and then return to shape — they don’t sag, bunch, or ride up, which is where a lot of chafe actually starts. No creeping seams, no wedgie readjustments every half mile.
• Flat, smooth knit. The jersey construction sits smooth against the skin with no bulky seams grinding at the inner thigh.

I put multiple-mile days in these on rolling terrain and finished with no hot spots, no raw patches, nothing. For anyone who’s ended a long hike walking like a cowboy because their underwear betrayed them, that alone is worth the price of entry.

Honest notes

The price. At $39 a pair, this is premium underwear, and buying a few pairs adds up fast. The value math works if you weight it against what you’re actually getting — fewer pairs needed per trip, years of durability, and comfort that genuinely changes your trail experience. But there’s no getting around the sticker on a single pair.

It’s a blend, not pure alpaca. Royal Alpaca is 14% of the fabric, with TENCEL and Pima cotton making up the bulk. That’s by design — the blend is what makes it soft, stretchy, and wearable — but if you came expecting a majority-alpaca garment, set expectations accordingly. The performance is real; the alpaca is the active ingredient, not the whole recipe.

Cotton content means slower dry than pure synthetic. The Pima cotton adds softness but the blend won’t flash-dry quite like a 100% synthetic technical brief if you fully soak it. In practice it dried fast enough for me, but it’s the honest trade for the natural-fiber comfort.

Who they’re for

• Buy them if: you take extended trips, thru-hike or do big-mileage days, want to pack fewer pairs, care about odor control and no chafing, or want natural fiber against your skin instead of synthetics.
• Skip them if: you want the cheapest option, or you specifically need the fastest-drying synthetic brief for high-sweat, wet-climate efforts.

PAKA Alpaca Underwear: the verdict

The best gear disappears, and trail underwear disappearing is the highest form of that compliment — because you only notice underwear when something’s gone wrong. Across multi-day camping and real thru-hiking miles, the PAKA Essential Boxer Brief never once made itself known. No stink, no chafe, no readjusting, no regret. The alpaca fiber does exactly what PAKA says it does, and after living in these on the trail, I’m not going back to synthetics.

At $39 a pair it’s an investment, but it’s the rare piece of gear where the upgrade is something you feel every single mile. Buy two pairs, take them on your next long trip, and you’ll understand.

FAQ

Can you really wear PAKA alpaca underwear for multiple days? Yes. Alpaca fiber is naturally antimicrobial and odor-resistant, so these stay fresh far longer between washes than synthetic or plain cotton underwear. Airing them out overnight resets them noticeably, which makes them ideal for extended camping and thru-hiking where laundry isn’t an option.

Do they prevent chafing on long hikes? In my testing, yes. Chafing is caused by moisture plus friction; the alpaca-and-TENCEL blend wicks sweat and dries quickly to keep skin dry, while the shape-retaining stretch and flat jersey knit prevent the bunching and riding-up that start chafe. I logged multi-mile days with no hot spots.

What are PAKA boxer briefs made of? 48% TENCEL (from eucalyptus), 33% organic Pima cotton, 14% Royal Alpaca, and 5% BPA-free spandex.

Is alpaca underwear itchy? No. Alpaca is lanolin-free — lanolin is what most people react to in sheep’s wool — so it feels soft and smooth against the skin, closer to cashmere than traditional wool.

How much do they cost? $39 for a single pair.

Are they good for travel? Excellent. The odor resistance and quick-drying blend mean you can pack fewer pairs, wear them longer between washes, and even rinse and hang-dry them overnight on a trip.

Is alpaca better than merino for underwear? Alpaca offers similar natural odor resistance and thermoregulation with a hollow-core fiber that’s exceptionally breathable and lanolin-free (so non-itchy). Merino typically dries a bit faster, but alpaca’s softness and antimicrobial performance make it excellent for next-to-skin wear.
