Consisting of Long-Sleeved Shirt and drawers, LVL 1 Underwear is the base clothing layer. This next-to-skin apparel reduces possible irritation and heat discomfort caused by high-energy output combined with military apparel and tactical gear carriage. Made of 100% polyester knitted fabric dries immediately and wicks moisture out of the body. This feature makes the LVL 1 Underwear a versatile solution that provides cool skin contact during hot days and pleasing warmth when the outside temperature drops. Moisture-wicking weave increases the evaporation area.
