Lé Bent Lightweight Crew Base Layer (Men's)
The Men’s Lightweight Crew is your go-to base layer for four-season mountain missions and daily wear alike. Built with Lé Bent’s 200gm Signature Merino Blend, it fuses bamboo rayon’s silky softness with merino wool’s natural odor resistance, breathability, and thermoregulation. The result? A lightweight top that feels incredible next to skin, regulates your temperature in shifting conditions, and keeps you fresher for longer.
A slim fit and 4-way stretch deliver freedom of movement without sag or bulk. Flatlock seams and sculpted panels reduce friction and chafing, while the scoop bottom hem adds extra coverage under layers. With UPF50+ sun protection, this crew works just as well as a trail shirt in summer as it does under your shell in winter.
