What Our Gearhead(R) Experts Are Saying: "I wear these all season for everything from ski tours to chilly trail runs. They're super breathable, don't hold odor, and feel way softer than any other base layer I've tried." We reach for the Le Bent Lightweight Bottom when we want that barely-there feel without sacrificing performance. Blending merino wool and rayon from bamboo, Le Bent's Signature Blend brings temperature regulation, breathability, and odor resistance together in a buttery-soft package. Ideal for layering under shell pants or wearing solo on shoulder-season outings, this lightweight 200gm base layer wicks moisture, stretches with every stride, and holds up through repeated wear. Sculpted panels and flatlock seams enhance fit and comfort, while UPF 50+ protection makes it an all-season essential in the mountains or around town.
