The Vertex Jacket is the lightest zero degree (0oC/32oF) down jacket we’ve designed – for adventure racers, lightweight backpackers, bike-packers, multistage ultra-runners, lightweight campers and wilderness trampers and anyone who needs the lightest. Incredibly, it weighs less than a base layer and packs down into a teeny tiny pack. The long body length and high collar work to cut cold air ingress making for even warmer performance. Not bad, when you consider the 170g/6oz weight!

This astonishing zero degree (0oC/32oF) down top uses our whisper-light 18g/m2 Vertex fabric to provide total windblock, and rare 950 fillpower down ensures superbly weight-efficient insulation. A lightweight front zip, hand warmer pockets, and optional down-filled hood make this an outstanding piece with an incredible warmth-for-weight performance.

For the midsummer months we're launching our Vertex Collection: the lightest Down Vest, Jacket, Shorts, and Sleeping Bags in their class. Only available May and June at never to be repeated prices.
