StrapHabit Our Sailcloth and FKM Rubber Quick Release Hybrid Watch Straps combine the best elements of two of our most popular styles of watch straps. They feature the high-end appearance of our Sailcloth straps combined with the numerous benefits of our FKM rubber straps. These two-piece watch straps feature quick-release spring bars for easy, tool-free strap changes. Available in 20mm and 22mm. Two keepers hold the end of the strap securely in place.  Thirteen adjustment holes mean that these straps should fit well on any size wrist. Available with silver, or black PVD buckles. The inner lining is genuine FKM rubber. They feel nearly as soft and flexible as silicone, but are much stronger, and resistant to picking up fuzz, or cracking, plus it is waterproof and sweat-proof.  Compared to traditional vulcanized rubber, FKM adds increased durability, chemical, and heat resistance. It is also anti-allergenic, and scent-free.
