Wonderful value for money wave-style (used widely by Japanese brands on their divers) silicone rubber scuba diver straps with no-decompression tables, that are soft, flexible and very comfortable. They come in black, black without tables, blue navy, green, orange, red, white and yellow and in 4 sizes (18-20-22-24mm) and with 2 floating keepers. Their overall length is approximately 95/135mm. I will include a pair of good quality spring bars with each strap. Feel free to contact me for whatever questions you might have.
Extra: Try my Localtime FKM Wave straps with Quick Release bars (last photo), listed separately in the store.
