Scupper. It's hard to say it without smiling, or even chuckling a little to yourself. It's just one of those fun words. But more to the point, scuppers help block the holes in the cockpit of your sit-on-top kayak so your paddling shorts stay a bit dryer in the spring and fall. Grab the Ocean Kayak Scupper Stoppers and extend your season a bit. Check what size your kayak needs, and keep in mind that sometimes your kayak will need more than one size.
