When it comes to base layers, the Airblaster Merino Ninja Suit stands head and shoulders above the competition. It harnesses the power of merino wool for naturally breathable and odor-resistant performance, and comes with a movement friendly women's specific fit to keep you loose as a goose. A long 350° zipper around the waist makes it easy to pop a squat when nature calls, while thumb loops at the cuffs help keep everything in place while you ride.
