Excellent quality

I’ve had these for almost a month now using them as a base layer and I love them. I’m a boat captain for work and hunter in my free time in wet conditions and below freezing. I own similar thickness merino wool base layers from first lite and Sitka and I can say these leggings are better, I only have one complaint.
Pros
-very high quality feel
- soft and comfy
- as warm or warmer than my merino
- noticeably cooler than merino when inside or driving
Con
- not enough room in the crotch and I find myself pulling them up quite a bit

I am 6’1” and 200 pounds, I got a large and I just wish they came up a little higher with more room in the groin.

That said I highly recommend them and you won’t regret buying them

These are great for the cold. Very warm and comfortable. I'm 6'3" 190lbs and the large is a perfect fit

Softest and warmest I have worn yet

I live in the Pacific NW and am outdoors as much as I can be. That means a lot of rain and cold. I use merino almost exclusively but that is changing as I discover just how much more insulating and comfortable Alpaca is. Yes, it's a tad spendy, but you get what you pay for. If I am not using them to keep warm and dry outdoors, then I am lounging around the house in them. Highly recommend this company and their clothing!

Night heavier weight leggings for cold days

I've been looking for some heavier weight wool leggings for quite awhile. Most companies only seem to ~200 weight for men. I'm in love with alpaca even more than merino. These leggings worked great when I was out building trail in 23F winter weather. They do have a slightly itchy/scratchy feel when I initially put them on, but I don't notice it afterwards. Would buy again.
