Harmony Flat Canoe Knee Pads are extremely versatile. They are more than adequate for periodic kneeling, these pads are ideal for padding everything from kayak seats to roof racks. They also work with other outfitting components such as tightening the fit of hip pads or adding a little more height to a pedestal. Camping/tripping paddlers prefer flat pads, as they are less obtrusive than 3D contoured or shaped kneepads and insulate against cold as well. Mondo-Bond Adhesive recommended, follow all instructions carefully. Sold in pairs
