The incredible light weight and compactibility of the Vela Vest comes from leading sailmaking fabric from America’s Cup racing. This wind- and waterproof fabric uses Dyneema® yarns for near-bulletproof strength. You’ve seen Dyneema® as the white core yarns in rock-climbing ropes, and it’s also used in bulletproof vests. This fabric comes straight from sailing, where ultralight weight and extreme tensile strength come together in a sport where cost doesn’t matter. Only winning matters. We finish off the vest with water-repellent DWR-coated 50-gram stretch woven inserts for breathability. You get front wind protection and significant water protection in a piece that folds down to almost nothing when you stash it in your pocket.
