Its TECLOFT synthetic insulation is designed to retain heat even when wet, and dry out quickly so you stay warm on your adventures. And when you‚Äôre finished with it, the Lewis can be rolled up and thrown in your backpack with the rest of your gear. We’ve given our Lewis elasticated cuffs and bottom hems, and a hood you can easily adjust to fit a climbing helmet or your favourite woolly hat. We‚Äôve included an elasticated security cord in the pocket to keep your keys secure on the move.
