The Harmony Wilderness Systems Commander Bow Cover is designed specifically for the Wilderness Systems Commander 140 kayak. The Commander Bow Cover will shield you from waves, splash, spray and the sun. Constructed of heavy-duty 410 denier urethane coated nylon with double stitched seams, the Commander Cover securely connects to the SlideTrax rails via deck sliders and thumb screws. Its 4 wide implosion bars keeps the cover taught while creating more space for your legs underneath and ensuring water quickly beads off.
