ISOfrane dive watch straps
Original ISOfrane straps were manufactured using a compound called isoprene. And just what is isoprene? Isoprene is a, liquid hydrocarbon that is obtained in the processing of petroleum and is used as a raw, chemical material. Isoprene was far more durable, and maintained its looks. ISOfrane has since upgraded their straps to make them non-allergic, non-toxic and added even more durability and softness to rubber WITHOUT using silicon (the dust magnet). It just most likely the best dive strap you’ll ever own.
