Great product and warranty!

The warmest and most comfortable thermals I have found. Personally I found I had to size down to Small. I have 31/32 waist and 30/31 inseam and small fits nice and snug, medium would probably work if you prefer a looser fit.

This base layer is both WARM and COMFORTABLE! the fact it's 3/4, makes it even better, as there's no excess fabric in the boot! very warm, very smooth against the skin!
