USGI Base Layer Level 1 Thermal Undershirt

The US Army deployed the Extreme Cold Weather Clothing System (ECWCS) and part of that is the Level 1 Base layer "silk weight" garments.  These long sleeve, long panted undergarments are the next to skin layer.

Designed to wick moisture and lock in your body heat, use the base layer as part of a layered system to stay warm in the winter.  These pants are made by Polartec or Miliken as part of contracts for the US govt and Army procurement.  

Our inventory is well stocked with Condition1, like New samples. 

We love these shirts as a cool weather PT shirt, as a warming layer.  Just great stuff.  Quick drying, and comfy.  These won't last long, got a small batch from one of our local sources.
