The Seals Kayak Cockpit Drape X Universal Cockpit Cover is the larger of the two drapes, made to fit kayak cockpits from 45 - 60 inches. The Cockpit Drape X is also useful for protecting the seat on Sit-on-Top kayaks. Seals Kayak Cockpit Covers are constructed with medium-weight coated nylon pack cloth to keep the critters out of your kayak during storage. The cover uses bungee style cord to secure it to the cockpit. This cover is not watertight and will allow seepage if water pools on it. For a tighter, watertight fit and for a cover that can be used during transportation, check out the Seals Cockpit Seal.
