I just bought 5 pairs of Kari Traa base layer pants to replace old ones from Smartwool that have beaten up. I was concerned about the sizing based on the reviews, but I had no issues whatsoever. I ordered all larges, all 100% merino styles, and all fit great. The weight of the merino in each item makes the fit slightly different across styles, but I didn't experience the variation that other reviews indicated. These are great quality, they feel super, I'm warm -- no issues. This out-of-shape, 5' 8" mom ordered her regular pants size and is a happy camper. Go for it!
Wore these under pants loved them. I will never not wear them when traveling again. Do not hold smells great as a base layer under items. Wore them everyday for 4 days.
I usually love everything in this brand, but I was really disappointed in these thermals. Firstly, this new wide very tight waist band is unnecessary and very uncomfortable. I wanted to return them. However, one chilly morning I had no choice but to wear this pair. I feel sad just looking at them knowing the discomfort I will feel in the waist and hips. They are fairly warm. Still, I wish designers would go back to the original smaller more efficient waist band. I may have to start knitting my own long underwear if this style persists!
Very comfortable and lightweight so they fit well under my jeans and kept me warm in below zero windchill
Lightweight but warm. Not as itchy as some wool items.
