Lightweight 150 Essential Bikini Underwear with merino wool for breathable comfort during alpine pursuits
What Our Gearhead® Experts Are Saying:
"This merino bikini is a game-changer for active days in the mountains. It stays cool when I’m pushing the pace and keeps me dry with its moisture-wicking blend of wool and TENCEL™. It’s soft, breathable, and offers the perfect balance of comfort and performance for long days in the backcountry."
From summer alpine climbs to winter ski tours, the 150 Essential Bikini Underwear keeps us comfortable through every season. Made with a high percentage of merino wool, this base layer regulates temperature, wicks moisture, and naturally resists odors for all-day freshness. Lightweight TENCEL™ fibers add a cooling effect during high-output activities, while a touch of elastane ensures a snug, movement-friendly fit.
Designed for dynamic mountain athletes, this versatile underwear provides next-to-skin softness and exceptional durability. Whether we’re layering up for a cold-weather trek or sweating it out on a steep ascent, this essential piece moves with us, offering reliable performance in every condition.
