Rab's well-established, award-winning Xenon Jacket now uses the new Gold Active Insulation from PrimaLoft, offering higher levels of breathability and completely eliminating cold spots. This combined with PrimaLoft's ability to retain warmth even when damp makes the Xenon X an extremely versatile piece, perfect for everything from a windy belay at your local crag to spindrift belays high in the mountains.
