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, finished with POLYGIENE® permanent odor control for freshness over multiple days.

Treated with POLYGIENE® permanent odour control, perfect for multi-day use. Features a ¼ length YKK Montane reverse coil semi-auto front zip with an internal zip guard. Flatlocked seams on the inside and outside of the fabric eliminate chafing and increase durability.
