Engineered to be your lightest, most versatile summer layering piece, the Femund Warm1 Zip Neck combines thoughtful simplicity with technical performance. Whether you’re setting off at sunrise, reaching a windy summit, or winding down around the fire, this breathable midlayer keeps you comfortable through changing conditions.
Crafted from Norrona’s Warm1 fabric, this zip neck uses a soft mélange double pique knit made entirely from 100% recycled post-consumer polyester. The fabric’s dual-structure—smooth on the outside, textured on the inside—delivers excellent moisture-wicking performance and quick-drying capability, making it ideal for wearing either as a standalone top or over a light base layer. The inclusion of HeiQ Fresh FFL, a silver-free, bio-based anti-odor treatment, ensures long-lasting freshness without compromising sustainability.
The design is minimal yet functional, with smart features like a 1/2-length front zip for adjustable ventilation, a zip garage to prevent chin chafing, and an articulated elbow construction for better freedom of movement. A zippered chest pocket offers a handy stash spot for your phone or trail essentials, while a discreet hang loop makes post-adventure drying easy.
The result is a featherlight, packable layer you’ll reach for again and again on warm-weather missions.
