Women's Helium II Jacket

Built for flash storm protection, the Helium II is 6% lighter and 10% more breathable than its predecessor. An ultra compressible piece you'll never leave behind, it offers 30% more waterproof protection than the original. The Helium II is so light and packs down so small, you'll forget it's stuffed in your pack or clipped to your harness until you throw it on to ward off a sudden mid route downpour. Compressible to the size of a granola bar and completely waterproof, the Helium II doesn't waste space or add more than a feather's worth of weight.
