What Our Gearhead(R) Experts Are Saying:"I have been reaching for the Verglas 1/2-Zip Top on every cool morning hike this season and it has not let me down once. The fabric blend moves with you completely and the half zip is just right for managing heat on a hard push uphill without ever feeling like you need to stop and swap layers."The trailhead is cold and the summit is still a few hours away. That window between too warm and not warm enough is exactly where the Helly Hansen Verglas 1/2-Zip Top lives. The blend of nylon, polyester, and elastane moves with every reach and step without binding or bunching, and the moisture-wicking construction keeps you feeling fresh whether the pace is steady or all-out. The mock-neck collar and half zip give you real control over your body temperature on the go. Crack the zip on a steep switchback to dump heat, close it back up when the ridge catches wind. At just 7. 1 ounces and built to Bluesign standards, it is a midlayer that earns its spot in the pack on any cool-weather objective.
