Navy 100% Polypropylene Underwear

LIGHTWEIGHT SINGLE LAYER THERMALS- These single layer thermals are recommended for high endurance sports. They fit snug, but they do not compress like Under Armour products. They will keep you warm even when wet. Although polypropylene is a synthetic fiber, these feel very soft because the thread used to make the fabric is spun into very small fibers giving the fabric its softness. Polypropylene (aka Polypro) does not absorb any water. As a result, it dries extremely fast when wet. These are very comfortable for use while skiing, snowboarding, cross country, or even just wearing around the house. These are the same product as our Black Single Layer Polypro, but they cost less due to its high volume production.

AVAILABLE IN TALL SIZES AND YOUTH SIZES
