On technical climbs in freezing conditions, you need the warmth, but you don’t need the weight. Loaded with 800-fill ProDown™ insulation, the Summit Breithorn Hooded Down Jacket offers both. It delivers high-level warmth and compressibility while retaining its loft, even in wet conditions. There’s an attached, helmet-compatible hood and raglan sleeves for full arms-up mobility. We’ve also added underarm gussets for freedom of movement on the ascent. And if things get too hot and sweaty, you can pack this lightweight jacket into its pocket to keep it safely out the way. That’s not all – recycled materials make it better for nature.
