Men's Yuma Synthetic Boxer Brief

Ultralight synthetic boxer brief with an internal divider pouch and HeiQ Pure Antimicrobial for hot weather performance.

$50.00
COLOR:Walnut
SIZE:S

Purpose-built from the ground up to offer users our lightest weight next-to-skin layer with distinct advantages over traditional synthetic base layers. From spring turkey and bear hunts to the southern whitetail woods, insects and ticks are repelled. While in the western theater, the system actively dries out and resists odor for the most sweat-drenched days chasing archery season elk and pronghorns.

Yuma represents First Lite's approach to offering a performance-oriented synthetic base layer option, in tandem with the Merino base layers our brand has become synonymous with. Yuma offers 3 distinct benefits: 37.5® Active Particle Fibers to wick sweat and dry the garment, HeiQ Pure Antimicrobial to hinder bacteria growth and odor, and Burlington No Fly Zone® to actively repel insects and ticks. Built to create a comfortable advantage no matter the pursuit, especially across the warmer months.
