Thigh guards for Sit-on Top kayaks

I just recently purchased a sit-on top kayak and when I relax my legs, they press into the seat straps and the rivets to hold the seat in place. I typically use an enduracloth to cool off in the water so I can just tuck that under my leg but then I have to alternate between each leg. Are there any types of thigh guards that could go around the seat straps/rivet to keep from digging into my legs? Thanks!

I have pressure points on my lower leg in my SOT. I cover the with a very thin sliced of minicell and wrap with Gorilla Tape.
