Thankfully, the folks at BikeParka know exactly what you want in a reliable bike cover. They teamed up with a tent manufacturer from New Zealand to create a bike parka that stays put in wind, keeps your bike bone-dry in the wet, and packs down to the size of a water bottle when you're ready to roll.
The XL Cover is supersized to protect bikes with wider handlebars (up to 100cm), a child seat, or full touring panniers. The ripstop nylon is hard-wearing and seam-sealed to keep the heaviest summer rain off your bike, and its UV protection keeps your paint looking fresh under the hottest sun. A thick elastic keeps the cover secure around the bottom of your wheels - adjust the fit in big winds with the plastic toggle near the top. Enforced brass eyelets at the bottom of the bike add extra insurance for monster storms.
