Been doing open water swims in Southern CA the past few weeks and with the water temps dropping into the high 50's its time to get an insulated cap.

I tried my old surfing hood, but the neoprene strap really chaffed my neck. Barracuda, Orca, DeSoto, and TYR all make insulated caps. The TYR Warmwear cap is the only one that doesn't have a strap. Any recommendations?
