8th Layer™ baselayers are cool essential for early season to help stabilize body temperature as the day warms up and cools down. 8th Layer™ is the ideal choice for next-to-skin performance: cool to the touch and virtually weightless, effectively wicking to keep skin dry, with a comfortable unconfined feel that won't impede your shot and S3 antimicrobial technology to help control odor. It's the perfect first layer, alone or in combination with lightweight wool or fleece. Crewneck style shirt. Realtree Xtra camouflage.
