What Our Gearhead(R) Experts Are Saying:"This layer's been a staple on my winter hikes and shoulder-season trail runs. It breathes incredibly well for how warm it is, and the Dotknit fabric feels light but insulates like a midlayer. The quarter-zip helps me dump heat when I'm moving fast, and I love that it's made from 100% recycled material."When we're pushing through chilly trail miles or layering up for a brisk morning climb, the Dotknit Thermal 1/4-Zip Top is what we reach for first. The North Face designed this technical midlayer with Dotknit Thermal fabric to balance warmth and breathability when we're on the move in cold conditions. The double-knit construction uses engineered holes to actively move moisture away from the body, keeping us dry and comfortable during dynamic activity. FlashDry-Pro(TM) technology enhances moisture management, and the 100% recycled polyester build aligns with our goals to tread lighter. A center quarter-zip lets us regulate heat on the fly, and the hybrid raglan set-in sleeve construction delivers a full range of motion. Bound cuffs and hem keep the fit secure, whether worn alone or under a shell.
