Real military base layers built to manage moisture, trap heat, and disappear under whatever you're wearing on top. This collection covers the ECWCS Gen III thermal system — from silkweight Level 1 next-to-skin tops and bottoms, to polypro thermals, to Level 2 grid fleece — plus USMC FROG thermals, cotton waffle weaves, and the legendary GI woobie poncho liner.

Who It's For
