Destined for parts unknown, if you could only throw a few pieces in your pack we're confident that our new Quantum Half-Zip will make the cut. A durable, versatile base layer, the Quantum is equally at home under armor in the field or a jacket around town. Made from heavyweight Merino wool, its blend of technical performance with rugged style will make it a strong ally wherever your journeys take you.

  • Base Performance: Strong and versatile, the Quantum is a durable base layer for cooler temperatures.
  • Technical style: With a semi-auto locking zipper with wind flap, drop tail hem, and gusseted arm panels for fluid movement, our Quantum Half-Zip blends technical features with rugged styling.
  • Athletic Ability: Made to move, flat locked seams provide protection from chafing. Bar tack reinforced thumb loops provide additional coverage against the cold and a helping hand during the layering process.
  • Active Merino: Unlike traditional wool, our Merino collection is comfortable against the skin and designed for performance. Perfect as part of your layering system, it naturally regulates body temperature by trapping heat for insulation when you’re cold while still maintaining breathability. If high pursuit activities heat you up, Merino effortlessly wicks moisture away from your skin to keep you dry and avoid cold chills. Even if you’re caught in a sudden downpour, it will still insulate when wet. Naturally odor resistant, you can hit the ground running for days without being concerned about laundry. We use MAPP (Merino Advanced Performance Program) fabric to ensure it is created exclusively using Merino fibers sourced from the cleanest and purest New Zealand alpine environments. These all-natural benefits make our Merino collection for men and women the perfect one-and-done packing pieces.
