All About Wool Underwear
Yes. Merino wool underwear is known for its exceptional comfort. Unlike traditional wool, Merino fibers are ultra-fine and incredibly soft, making them gentle against your skin with no itch. They naturally stretch and move with your body, offering support without restriction. Whether you're hiking, working out, or just going about your day, Merino wool underwear keeps you comfortable in all conditions.
Merino wool is one of the healthiest fabrics you can wear. It's naturally antimicrobial, which helps prevent the growth of odor-causing bacteria without added chemicals. It’s also breathable and temperature regulating, which reduces the risk of irritation, chafing, or overheating. For people with sensitive skin or those looking for a natural alternative to synthetics, Merino wool offers a clean, chemical-free solution that feels great on your body.
All of our Merino Wool Underwear is OKEO-TEX STANDARD 100 certified meaning its been tested & proven safe against a list of over 1000 harmful chemicals including PFAS.
Definitely. Merino wool is one of the most versatile fabrics you can wear daily. It regulates your body temperature, keeping you cool in the heat and warm in the cold. It's also naturally odor resistant, so you can wear it longer between washes without worrying about smells. Breathable, lightweight, and moisture wicking, Merino wool underwear is ideal for everything from commuting and lounging to running errands or hitting the trail.
Our men’s Merino wool underwear collection features multiple styles, including briefs, boxer briefs, and pouch options designed for performance and comfort. Our Acadian 100% Merino boxer brief is our most popular, but we also offer styles with added stretch for a sportier fit, pouch options for extra support, and lightweight versions ideal for high-output activity. Each style offers flatlock seams to reduce chafing, moisture wicking properties to keep you dry, and a snug yet flexible fit that adapts to your movements. Whether you’re hiking, skiing, or traveling, our men's Merino wool underwear offers lasting comfort and all-season performance.
Yes. We offer a full range of women’s Merino wool underwear designed with fit, comfort, and performance in mind. From boxer briefs, to bikinis and boyshorts, our women's merino underwear collection performs better than cotton, offering soft, breathable fabrics that conform to your body, wick away moisture, and resist odor naturally. They're perfect for active lifestyles, outdoor adventures, or simply staying comfortable throughout the day.
One of the unique benefits of Merino wool is that you can wear it for several days in a row without it smelling bad. Its natural antimicrobial properties resist odor and bacteria buildup, making it perfect for extended use during travel, backcountry trips, or busy weeks. While we always recommend washing underwear regularly, Merino wool can stretch between washes more than cotton or synthetic alternatives which hold bacteria.
