The Dart Zip Neck is a classic, all-season, all-mountain technical baselayer made from 100% recycled APEX ECO fabric. It offers an ideal combination of warmth, moisture-wicking, and breathability, with POLYGIENE® permanent odor control for freshness over multiple days. The garment is constructed using light, wicking, and soft APEX ECO 100% recycled polyester fabric with a super-wicking pique textured backer. It features a ¼ length YKK Montane reverse coil semi-auto front zip with an internal zip guard and flatlocked seams for comfort and durability. The lightweight fabric is highly breathable, making it ideal for versatile and fast-paced activities. It's a comfortable next-to-skin layer that regulates warmth and wicks sweat during high-output activities while actively stopping odor with its anti-bacterial properties.
