Rated 5 out of 5 by Excellent quality This runs true to size and is very well made. Highly recommended. October 5, 2016
Rated 4 out of 5 by heavyweight baselayer I have been looking for a good baselayer for some time now. I have tried just about every manufacture out there. They just would not fit right, the material would not feel good or they be full of static witch I can't stand. This baselayer is the only one I found that fit true to size felt good kept me warm in 30 degree weather and kept me cool when I started sweating. I plan on buying another pair to have as a extra.

Rated 2 out of 5 by This product has great features I received a pair as a Christmas gift. I like the feel. They where even able to find them in a tall, which is amazing. It's so nice to have something long enough, even if they did have to go to the men's department for it. I was looking forward to the warmth of long johns from my youth, and I just didn't get that.

Rated 5 out of 5 by Great product! Bought these as a Xmas gift for my brother in law who is a salesman at a car dealership and has to fight the winter cold - going in and out of the showroom all day. He was looking for a quality pair for a long time and he just loves them. His best Xmas gift! Thanks Columbia! February 3, 2016

Rated 2 out of 5 by Not warm I love the Omni heat products but this one is not warm. At only 32 degrees outside I could feel the air through these and my pants. I would not recommend them. January 23, 2016
Rated 5 out of 5 by Heavyweight tight I am very pleased with how this article of clothing performs in the cold weather. Exceptional warmth for the outdoor enthusiast! January 21, 2016
Rated 5 out of 5 by Staying warm I'm a huge Columbia fan. if you want to stay nice and warm buy these! As alway Columbia's quality shines with this product. January 16, 2016
Rated 3 out of 5 by Baselayer I was excited to get these pants and use them under my ski pants when i skied. I wore them on a pretty warm day under my ski pants thinking they were going to keep me warm. Big mistake! These did not keep me warm at all. I was cold. The material was great and price was good. I was bummed the micro beads didin't do their job. These pants should be labeled medium weight instead of heavy weight. My long johns keep me warmer than these pants. December 30, 2015
Rated 5 out of 5 by In a Tight Spot This is another outstanding product from Columbia Sportswear. It fits great, has the potential for being worn comfortably a long time on many days, and for keeping one warm and dry. It's just perfect. October 7, 2015
