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.

Alpaca wool leggings. 420 midwinter. Fabulous

I bought these wonderful leggings online living in the UK. I was nervous thinking would they arrive from Peru... well they did. The online purchase was really easy and confirmation of my purchase was email returned. I got updates via emails and they arrived safely. I am delighted with the quality and fit. The sizing chart was accurate. I really do recommend this company and their product. Thank you
