A lightweight, single-layer pullover, our Comfort Shell quarter-zip top is the perfect addition to those looking for sweat-protection and trapping heat with an additional layer without being weighed down! You'll feel the difference of our breathable, lightweight technical fabric as a mid-layer addition to outerwear with a convenient semi-fitted style, 360 low-profile collar and flat seam stitching throughout. It's engineered to stay fresh with anti-microbial properties and stay put with a perfect 4-way stretch fit. The brushed interior is super soft against skin, keeping irritation and chafing at bay. The High Energy Carapace is used for indoor and outdoor plans: wear it to the mountain, for your apres ski, under your jacket, alone or as a base layer.
