"What Our Gearhead® Experts Are Saying: ""I’ve worn the Solution 1. 0 Hoodie on big approaches and cold belays—it breathes well during high-output missions but still keeps me warm when I stop. It’s a perfect mix of insulation and mobility, and the stuffable chest pocket is a nice bonus when I’m trying to save space."" The Black Diamond Solution 1. 0 Hoodie is built to handle the varied demands of the mountains with versatility and technical performance. Lightweight PrimaLoft® Gold Eco insulation keeps us warm when temps dip, while stretch-woven fleece panels allow for dynamic movement on the wall or under a shell during alpine missions. Whether we’re chasing fall temps at the crag or layered up for a summit push, the Solution 1. 0 blends warmth and breathability for comfort across a range of pursuits. Its 20D nylon shell with PFAS-free DWR helps repel light moisture and wind, and we love that it stows neatly into its own chest pocket—ready for transitions or when weather shifts. Helmet-compatible hood and stretch-knit cuffs mean it’s ready to move with us, not against us, when the terrain gets technical."
