The Helium Jacket may be one of Peak Performance lightest down jackets, but don't be fooled into thinking it's a lightweight; no matter how low the temperatures go, it will always make sure you don't get left out in the cold. They've combined ultra light, resilient fabric with 700-fill feather down and Thermocool® padding for premium warmth and breathability. Cosy enough for snowy action, yet cool enough for urban adventures.
