The Seals Sprayskirts Tandem Cockpit Drape Cover fits securely to the cockpit area of your kayak and works well with sit-insides without pronounced rims. Another great use of this drape cover is for Sit-on-Top kayaks, and their seats. Constructed with a medium-weight coated nylon pack cloth, this cockpit cover will keep your kayak from becoming a house for unwanted critters between paddle sessions. The Seals Kayak Tandem Cockpit Drape is fastened to your kayak using bungee style cord. This cover is not watertight and will allow seepage if water pools on it, making this a good cover for an indoor or covered area.
