Our StrapHabit Rubber straps are extremely durable, and comfortable. The deep colors look fantastic! Quick release springbars allow you to quickly swap straps in seconds without tools. These straps are NOT silicone, they are genuine FKM rubber. They feel nearly as soft and flexible as silicone, but are much stronger, and resistant to picking up fuzz, or cracking. In the photos, you can see how flexible that they are, and that they can be completely folded without stretching or cracking. Compared to traditional vulcanized rubber, FKM adds increased durability, chemical and heat resistance.
