USGI Military Polartec Silkweight Power Dry Thermal Underwear Shirt & Pants Set
Very good thermal underwear which is used as Level 1. Base layer is used to keep you dry. Keeps your skin dry when you sweat, good for both hot and cold weather. Higly breathable, dries quickly.
The most comfortable and lightweight thermal underwear I ever used.
Made for Marines, so you can be sure that it is a high quality product.
Manufactured by Peckham Inc under the Polartec brand.
Very good, reliable and inexpensive set, highly recommended.
