Self-adhesive closed mini-cell foam contoured hip wedges that can be further shaped and customized with the supplied sandpaper.
These work well in my play boat. The pre-applied glue seems to be holding up very well. The included sandpaper allowed me to shape the pads very effectively to fit how I wanted. Just as an FYI, once sanded the pads become much grippier, which can make it hard to slide yourself in your boat if you want a really tight fit. I may sand them down a little more or put some duct tape on them to so I will slide in the boat more easily. I'd buy these again in a heartbeat.
Exactly what I was looking for. Hip pads on my perception were getting wore out. Kayak fits me like a glove now!
