Base Layer Tops

A hybrid merino wool baselayer that manages moisture to keep you dry during any high-output, cold-weather pursuit. A year-round, cold-conditions baselayer that manages moisture during high-output pursuits on foot, skis or two wheels, the Basis PeakWool™ Half Zip features a highly breathable, layered construction that offers the benefits of both natural and synthetic fibers. Made with PeakWool™ Double Jersey fabric, the Basis features soft, ultra-fine merino wool next-to-skin to wick moisture, and a quick-drying polyester outer that adds strength and durability. The fabric also features a high-efficiency grid backer, which traps warm air, aids in moisture transfer and makes for faster drying. The classic zip-neck design provides added coverage and quick ventilation, while flatlock seams make for chafe-free comfort when you’re on the move. PeakWool™ Double Jersey, Double Knit Jersey, 56% RWS-Certified Merino Wool, 23% TENCEL™, 12% Recycled Nylon, 7% Nylon, 2% Spandex, 280g/m2 PeakWool™ Double Jersey is a midweight fabric constructed with Merino Wool, TENCEL™, Recycled Nylon and Spandex. The natural properties of Merino regulate body temperature, keep odors at bay and manage moisture to keep you dry.

PeakWool™ excels in cold temps by keeping your core warm and dry, while enabling heat transfer when the tempo picks up.
