What Our Gearhead(R) Experts Are Saying:"The Mayen Quilted Jacket has become my go-to between-effort layer on cold Nordic days because the compact synthetic insulation warms up fast and the stretch underarm panels never restrict my movement when I need to get moving again quickly. It works just as naturally on a cold trail run as it does at the start line."The Swix Mayen Quilted Jacket is built for the kind of winter that demands versatility from every piece in your kit, whether that means wearing it as a standalone layer on a cold Nordic ski outing, throwing it over a base layer for a chilly morning run, or using it as an insulating mid-layer when the temperature really drops. Compact synthetic insulation with a unique quilted pattern traps warmth efficiently and prevents the after-chill that sets in when effort levels drop, while stretch panels under the sleeves keep movement unrestricted when it is time to push again.
