Experience Unrivaled Comfort with Smartwool Outdoor Gear

Embark on your next adventure with the confidence that only Smartwool can provide. As a pioneer in performance Merino wool apparel, Smartwool has revolutionized the way we experience the outdoors. At trekkinn, we are proud to feature a brand dedicated to keeping you comfortable, dry, and ready for anything, from a brisk morning trail run to a multi-day alpine expedition. The secret lies in their intelligent use of high-quality, ZQ-certified Merino wool—a natural fiber that outperforms synthetics in every critical way.

The Foundation of Your Adventure: Smartwool Base Layers

The core of any effective outdoor layering system is the piece that sits next to your skin. Smartwool base layers are engineered to be the ultimate first layer, acting as a second skin that intelligently manages your body´s microclimate. Forget the itchy, bulky wool of the past; Smartwool´s Merino is incredibly soft, breathable, and comfortable for all-day wear. Its natural ability to regulate temperature means it keeps you warm in the cold and cool in the heat, making it a true four-season solution for hikers, skiers, climbers, and trekkers.

One of the most remarkable properties of Smartwool base layers is their superior moisture management. The fibers actively pull sweat and moisture vapor away from your skin and transport it to the outside of the fabric, where it can evaporate quickly. This process, known as wicking, is crucial for preventing the chill that occurs when you stop moving. Furthermore, Merino wool is naturally odor-resistant, meaning you can wear your base layer for days on end without worrying about odor buildup—a game-changer for long treks and minimalist packing.

To meet the demands of any activity or climate, Smartwool offers its base layers in different weights. Discover the versatile Merino 150, an ultralight layer perfect for year-round use, high-output activities, or as a featherlight first layer under other insulation. For colder conditions and winter sports, the best-selling Merino 250 provides exceptional warmth and insulation without the bulk, ensuring you stay toasty on the ski lift or at a frigid campsite. With thoughtful designs featuring flatlock seams to prevent chafing and an athletic fit that moves with your body, every piece is crafted for maximum performance and comfort.

While renowned for their base layers, Smartwool´s innovation extends across a full range of outdoor essentials. From their legendary performance hiking and ski socks that cushion and protect your feet to cozy mid-layers, beanies, and gloves, you can build a complete head-to-toe system rooted in the natural performance of Merino wool. Equip yourself with Smartwool at trekkinn and discover the difference that a smarter first layer can make on your performance, comfort, and overall enjoyment of the great outdoors
