"Every fiber in the Helly Hansen Evolved Air Hooded Midlayer comes from Ocean Bound recycled polyester, sourced from coastal regions at risk of plastic pollution, and built as a single material so the whole piece can be recycled again at the end of its life. A high protective collar and constructed hood guard against the elements, while flatlock seams and an anti-chafe chin guard keep the fit comfortable against the skin. It's a midlayer built to do its job twice over, once on the trail and once again after. What Our Gearhead® Experts Are Saying:""I wore the hood cinched down through a sleety commute and the chin guard kept the zipper pull from catching on my scarf underneath. The flatlock seams stayed flat and unnoticeable the whole walk."""
