Split padding for wide rack bars, with Velcro closures and bungee ties. Protects kayaks, surf skis and surfboards from hard bars and prevents slippage. The 30-inch length will fit most solo kayaks. Made of fade-proof, rugged fabric that will not tear, rot or sun damage. Internal foam tubing cushions cargo from bumpy roads. The Aero Size fits wide crossbars (pad is 1 7/8 inches inside diameter and can open wider. Fits bars up to 10 inches in girth). Other lengths are available, some by special order. Sold as pairs.
