If you have an issue with a rash when you wear polyester long johns just try these. Amazing feel and no rash.

I have been wearing 'performance' base layers for years. I have not been impressed...until this. Boundary Waters canoe trip in May. I slept in my base layer, got out of my hammock, paddled and fished all day. Total comfort!

I order these for my husband who owns a food truck and is outside, in the mountains, everyday. He LOVES them under his Chef pants.

These base layer bottoms are my go-to for cold day runs here in Maine (sub 15F). They are totally comfortable and keep my legs warm underneath my running tights. I also put em on at night at home: nothing better to lay around in on these long winter nights.

Bought these to replace some polyester bottoms I've had for a while...these are softer and much more comfortable. I expect have them for years. I'm 5-10 and weigh 165...great fit.

I haven't worn them for activity yet, but they feel great when I try them on. I feel like they'll make a great addition to my camping gear. Thank you!

They're alright, but they wear out too quickly and are too expensive

Just wore them for the first time in 20 degree weather downhill and backcountry skiing in New Hampshire and they are fantastic! Warm, breathable, and comfy!

Super comfortable and warm. I have been using the all weather bottoms and two different weights of the 1/4 zip tops for years now and have no complaints.

These pants are a game changer. I'm out in the cold a lot for work, and nothing has been keeping me warm?until these! They're thin enough to wear under other pants, and they keep me so warm. I absolutely love them!

Live in Michigan so weather is cold in winter, work outside and inside so I needed a base layer that was warm enough and at same time wouldn't overheat when indoors ! Great product soft and fits perfectly.

This base layer is great for being out in the field doing trail work especially during cold and wet days. The bottoms are comfortable and give me just right amount of warmth without restricting movement.

Very very warm
By Backpack J.
I got these for backpacking and staying warm in the winter, and I'm very impressed. I've owned running leggings in the past that were thicker and heavier but not as warm. These don't do great against the wind (layering is key) but trap body heat well and are reasonably rugged for how sheer they are. These are warmer than any other tights I own and I can wear them comfortably under jeans or wind pants.
Best ever
By Dan
They don't ride up, they don't sag down! Best long johns I've owned! Keep my legs super warm on a cold day but don't over heat them when I'm hiking 1,500 feet. Must buy!
