What Our Gearhead(R) Experts Are Saying:"These are the bottoms I reach for when I know I'll be out in the cold all day. They're warm, soft, and don't hold onto odor, even after a long tour. Plus, the stretch keeps them from ever feeling restrictive under layers."When winter rolls in, we count on the Midweight Bottom as a foundational layer that keeps us warm without the bulk. Whether we're chasing powder turns or hiking snow-packed trails, this merino-rich baselayer helps us stay comfortable and focused no matter how low the temperature drops. The performance blend of bamboo rayon, merino wool, and elastane delivers the perfect mix of softness, warmth, and stretch. Merino naturally regulates temperature and resists odors, while bamboo rayon enhances moisture management and comfort. With a next-to-skin fit that moves with us, this midweight option adds reliable insulation under shells or insulated pants.
