Reviews

Rated 5 out of 5 by from Great base layer for the price I just didn't feel like spending $50 or $60 on base layer bottoms that the top-shelf competition offers and thus went with these and have no regrets. They seem well-made, are soft/comfortable to wear and the size large fits my 6' 180 pound frame perfectly.

Rated 5 out of 5 by from Excellent baselayer Part of my hiking gear for a mount Whitney trip on October 3 2017. Sub 30°f temp with winds up to 40mph. Fit was comfortable. Was not scratchy. Remained remarkably comfortable in the the cold weather. Did not feel swampy. Very light.

Rated 5 out of 5 by from Far warmer than their weight Beats the last two pairs of North Face that i've had, but still way more comfortable, looser, lighter and warmer. Can't explain how, but it works.

Rated 5 out of 5 by from Underwear? I wear these as pants If you've always wanted to walk out in public in your underwear, but have been a little hesitant to do so... this is the perfect first step. These bad boys keep not only your lower (sometimes better) half warm, but they also make your lazy self look like you just came from the gym. Women in leggings? Meet men in long underwear.

Rated 2 out of 5 by from Too loose around the calf Too loose around the calf and I have huge calves. I'm returning one of the two pairs I bought (only keeping the one because I wore them already).

I found these looking through the extended sizes/ tall section, but don't see an option for ordering a tall size. Do they come in 35-36" inseam or just the 31" and 32"?

Asked by: EmilyB
​No, these light weight bottoms come in the extended size XXL, but not tall.
