Alpaca for the heat. Merino for the shape.

Warm when the ground is frozen

Alpaca and merino keep insulating even when damp, so the cold of the snow and the sweat of the walk in don't reach your toes.

Merino keeps the shape

Merino is spun into the same yarn as the alpaca, so the sock springs back and stays up in the boot instead of sliding down.

Cotton sockALPATHERM™

Cotton vs. ALPATHERM™

A cotton sock slumps to the ankle and holds the sweat. The ALPATHERM™ stays up over the calf, warm from the walk in to the long sit.

Stay for the last hour. Warm feet decide it.

Alpaca for the heat, merino for the shape, in an over-the-calf hunting sock: from the walk in through wet grass to the long sit in the snow.

THE RIGHT COLOUR FOR YOUR GROUND

Where the ALPATHERM™ works best, and which colour to pick for your boots and your ground.

Best use
Tree stands, ground blinds and long sits in the cold, plus walked-up days and multi-day hunts in the boot.
Conditions
Cool to very cold days, frost, snow and wet ground. Alpaca and merino stay warm when damp.
Fibre blend
50% alpaca, 30% merino, 16% nylon, 4% elastane: 80% natural fibre. The merino is spun into the same yarn as the alpaca and gives it shape memory.
Not designed for
Hot weather and low-cut shoes. Long wades without waterproof boots.

INSIDE THE ALPATHERM™

Alpaca for the heat, merino for the shape, nylon only where the boot rubs. Four field colours, sizes M to XL.

WARM AT FIRST LIGHT. STILL UP AT LAST LIGHT.

Cold feet end more sits than any buck ever did.

You climb in before dawn, sit still for hours, and the cold starts at your toes. Thin socks lose the fight. Thick wool itches and holds sweat from the walk in. And most alpaca socks, warm as they are, end up bunched around your ankle by mid-morning.

ALPATHERM™ fixes all three:

1. 50% alpaca that stays warm even when damp.
2. 30% merino spun into the same yarn, so the sock keeps its shape and stays up.
3. Thermal terry under the foot, and nylon only where the boot rubs.

Warm feet. All day. Stay for the last light.

ALPATHERM sock with close-ups of the knit: alpaca for warmth, merino for shape memory

Warm feet from the walk in to last light.

An over-the-calf hunting sock in four field colours: alpaca for the heat, merino for the shape, nylon only where the boot rubs and thermal terry under the foot.

WARM WHEN DAMP

Alpaca and merino keep insulating when sweat from the walk in or melted snow gets into the boot.

02

STAYS UP ALL DAY

Merino spun into the same yarn gives the alpaca spring, and a soft ribbed calf holds the sock in place without squeezing.

BUILT WHERE THE BOOT RUBS

Thermal terry under the foot, heel and toes, a flat seamless toe, and nylon only at the heel and toe, where boots wear socks out.

NO ODOUR, DAY AFTER DAY

Natural fibres with no chemical treatments. Rotate two pairs on a multi-day hunt and they stay fresh.

What customers say about our fleece-lined Complete Outdoor Set, the kit these socks were built to go with. ALPATHERM™ reviews will show here as they come in.

I went up a size to leave room for thicker layers, and I’m glad I did. The trousers cover my boots properly, and I can bend down without feeling restricted. Had it out on a cold, windy afternoon with some rain, and the wind protection was what I noticed most.

Mark J. (Canada) wearing the Complete Outdoor Set
First morning out was windy and I wasnt constantly feeling it through my sleeves. Happy with that.
Customer, United States
Good for the price. Pants are a little long on me but work fine over boots.
Customer, United States
Wore it checking cameras before daylight. Normally come back with wet pant legs from the grass, this time much better 👍
Customer, United States
The fleece is comfortable against my arms. I hate that cold slick feeling some jackets have inside.
Customer, United States
Warm walking to the stand, had to unzip halfway there. Once I sat down I was glad I had it.
Customer, United States
I hunt from the ground mostly and being able to crouch without fighting the pants is a big plus.
Customer, United States
Fit the jacket fine, pants tighter than I expected around the thighs. Check both measurements.
Customer, United States
Decent set but warmer than I need for a steep hike. Better when I'm moving slow or stopping alot.
Customer, United States
Trousers slightly long but otherwise a decent fit. Plenty of room in the jacket with a jumper underneath.
Customer, United Kingdom
Not as rustly as the cheap waterproofs I was wearing before. You can still hear it against branches.
Customer, United Kingdom
I'd like a shorter leg option. Keeping it because the rest fits comfortably.
Customer, United Kingdom
The jacket doesn't pull across my shoulders with the binoculars up. Much better fit than my old one.
Customer, United Kingdom
Quiet enough for how I hunt. Wouldn't call any fabric completely silent.
Customer, Canada
Before I use jeans and get cold sitting. With this is more comfortable, specially early morning.
Customer, International
Chris B. (Canada) wearing the Complete Outdoor Set
Been using mine for early morning trips and it has become my go-to set now. Warm enough with a layer under it and does not make loads of noise when walking.
Chris B. · CanadaVerified
Bought it for deer season. Comfortable walking in and enough room to sit without the waist digging into me.
Customer, United States
I was not sure about ordering clothing online because sizing can be a mess, but this one actually fits right. Pants sit good over my boots and jacket has plenty room to move.
Robert H. · USAVerified
Robert H. (USA) wearing the Complete Outdoor Set
Not magic winter gear. Still wore my thermals underneath on a cold sit, but it worked well as the outer layer.
Customer, United States
Expected the lining to be only in the jacket. Nice having it in the pants too.
Customer, United States
I dont have a huge gear budget. Getting both pieces together made more sense for me than another expensive jacket.
Customer, United States
Bought mainly for woodland stalking. Much nicer than having cold, damp trousers brushing against your legs all morning.
Customer, United Kingdom
Been out in drizzle a couple of times and stayed comfortable. Haven't tested it in hours of heavy rain.
Customer, United Kingdom
My usual problem is buying a warm jacket and forgetting my legs are still freezing. This sorts that rather well.
Customer, United Kingdom
I checked the measurements instead of guessing my normal size. Glad I did, the fit isn't the same as my work clothes.
Customer, Canada
Value seems good so far. The real test will be how it looks after more wear and washing.
Customer, Canada
I order my normal size without checking. Pants tight for me with extra clothes under.
Customer, International
My legs usually get cold before anything else when I'm sitting in the stand. The lined pants made more difference than the jacket honestly.
Customer, United States
Less swishing than my old rain jacket. Not completely silent but definitely an improvement.
Customer, United States
I was tired of hunting in work jeans and whatever jacket I could find. Having an actual set is nice.
Customer, United States
I can reach up and climb without the shoulders pulling tight. That was my biggest issue with the last jacket.
Customer, United States
I do more sitting and watching than walking. The lining in the trousers is very welcome.
Customer, United Kingdom
The collar comes up nicely. Still need a neck warmer when its properly windy.
Customer, United Kingdom
Didn't want to spend silly money on kit I use a few weekends a month. Happy with the value.
Customer, United Kingdom
First time using in wind and very happy. Still need gloves, my hands were cold 😅

Mark T. (UK) wearing the Complete Outdoor Set
Wore it all morning in wet grass and honestly stayed way drier than I expected. Fit is good too, not too tight when moving around. Really happy with it.

Philippe M. (France) wearing the Complete Outdoor Set
Very comfortable and lots of useful pockets. I was outside for almost the whole day and did not feel restricted at all. Delivery was also faster than expected.
Philippe M. · FranceVerified
Bought this to replace some really noisy waterproof pants. These are quieter moving slowly through cover.
Customer, United States
The wind protection is the best bit for me. Out across open fields you notice it straight away.
Customer, United Kingdom
Can sit down without the waistband cutting in. Sounds basic but plenty of outdoor trousers get that wrong.
Customer, United Kingdom
The pants are the part I appreciate most. I already had warm jackets but nothing decent for sitting.
Customer, Canada
Jacket fits better than the pants on my build. Wish I had checked the waist more carefully.

My old jacket make noise every movement. This one less noise and more comfortable.
