I definitely wouldn't recommend wearing these when the weather is above 0. They're almost *too* good imccold weather, and they're so comfortable that I almost forgot that I was wearing them.

Great bottoms but the leg length is short and in winter if you are 6' plus you will need socks pulled up.
Would recommend getting a size up.

Additional Product Information
Composition
Main fabric
- 100% Polyester cationic, 100% of the thread is dope dyed
What is the fit of the 100 base layer?
The 100 base layer comes in a regular fit. It's a classic straight cut suitable for all body shapes.
What are the benefits of polyester?
Polyester is the most used fiber for base garments because it is relatively inexpensive and offers excellent performance in some respects, especially because the fibers can be knitted to obtain a very lightweight and durable fabric. It actively absorbs moisture but does not dry particularly well when wet. It is limited in its ability to reduce odors.
