Prepare for high-output hunts in hot weather with the Men's First Lite Wick Long Sleeve Crew. This ultralight base layer features a 150-gram Aerowool construction, combining 17.5-micron merino wool with 37.5 active particle technology to rapidly exhaust moisture and trap human odors. Targeted 125-gram Aerowool mesh panels maximize ventilation during active pursuits, keeping you cool when the action heats up. Complete with flatlock seams and an ergonomic cuff with thumb loops, this next-to-skin layer ensures all-day comfort while eliminating shine with its naturally UV-absorbent fabric.
