Gear Review: Polarmax Light Weight Tech Silk Men's Crew Baselayer

The most affordable baselayer that still get the job done right.

[bargain]

When you’re working hard in moderate temps—whether snowy or rainy—you don’t want much insulation from your baselayer, just something to move sweat and serve as a liner for an outer shell. This filmy shirt fits the bill perfectly, without busting your budget along the way. It’s the lightest baselayer we tested, made of 100-percent polyester so thin it’s see-through (despite the model name, there’s no silk). Our sweatiest male tester immediately tagged it as his “go-to base for high-effort outings and skin-level use in multi-layer stacks.” Despite a proprietary antimicrobial treatment, it can stink a bit, but it also offers near-instant drying after sink or stream rinsing due to the lack of spandex. The fabric gives somewhat, but doesn’t really stretch, so size accordingly. $25; 3.2 oz.; m’s S-XXL, w’s XS-XL; polarmax.com
