The Monsoon is an ultra-lightweight waterproof shoecover. Its seamless design is possible through the use of eVent Spider, a lightweight breathable material that is both waterproof and wind proof. A velcro closure above the ankle helps prevent water from seeping down the leg into the cover. The rear zipper is slightly raised to prevent damage when off the bike and is covered with reflective flaps to increase visibility. There is an independent tab below so you can pull the cover on without putting stress on the zipper. However, there is also a Velcro closure tab on the bottom such that the cover can be opened completely, allowing you to pull it over your shoe before putting it on then pulling it down over the shoe.
