Pull them out of a pack, dig them out of your RocektBox... wherever you stash your Hurricans, when you need them you'll be happy they're at hand. Two-layer waterproof-breathable Hurricane fabric sloughs off tire spray from your mountain bike or wind-lashed rains on a ridgeline. PVC-free seam taping is weatherproof as green as it gets. Fourteen-inch ankle zippers help pull them on in a hurry and protect them from dirty boots.
