Men's Alpine Onset Merino 150 Bottoms

A soft, breathable, moisture-wicking foundation for active layering, the Alpine Onset Merino 150 Bottom pairs non-mulesed merino wool with polyester and Lycra® for stretch that moves with the body. Built for skiing, snowboarding, climbing, and hiking — keeps you comfortable from first chair to après.

Non-Mulesed Merino Wool Blend
53% Merino Wool sourced from non-mulesed sheep delivers natural anti-odor performance and next-to-skin softness for multi-day comfort.
Lightweight 150 g/m² Knit
Lightweight construction layers cleanly under shells and mid-layers without bulk — perfect for high-output activity and shoulder-season wear.
Naturally Anti-Odor
Merino wool naturally resists odor-causing bacteria — wear multiple days between washes on long trips and alpine pushes.
Breathable & Wicking
Knit construction pulls sweat off your skin and lets it evaporate — keeps you dry and comfortable through high-output ascents and cold descents.
Quick-Drying
Synthetic blend dries faster than pure merino — wash in the evening and wear again the next morning on multi-day trips.
UPF 30 Sun Protection
Built-in UPF 30 rating shields skin from UV exposure on shoulder-season hikes and spring ski tours when you strip down to base layers.
Flat-Seam Construction
Chafe-free flat seams eliminate irritation under pack straps, harnesses, and against bare skin during repetitive motion.
Elastic Logo Waistband
Low-profile elastic waistband lays flat under mid-layers and shells without rolling or digging in.
Gusseted Crotch
Diamond-shaped gusset delivers unrestricted range of motion for high steps, deep lunges, and climbing movements.
Shaped Functional Fly
Functional fly designed for comfort and convenience under layers.

Machine Wash Cold
Wash on a gentle cycle with like colors in cold water. Use a wool-safe or technical base layer detergent to preserve the merino's natural softness and anti-odor properties.
Tumble Dry Low or Hang Dry
Tumble dry on low heat or lay flat to dry. Avoid high heat to prevent shrinkage and damage to the merino fibers.
Do Not Bleach
Bleach will damage the merino wool fibers and degrade the natural anti-odor performance.
Do Not Iron
Heat from ironing will damage the merino fibers and degrade the Lycra® stretch recovery.
Do Not Dry Clean
Dry cleaning solvents will strip the natural lanolin from the merino wool and damage the synthetic blend fibers.
Store Folded, Not on Hangers
Hanging merino base layers for long periods can stretch out the fabric and waistband. Fold and store in a drawer or packing cube.
