ISOfrane is one of the foremost dive watch straps on the market. Originally developed in the 1960s, these rubber straps are designed to be both comfortable and durable. In addition to being super soft, the strap has large ventilation slots to both allow the skin to breathe, and for water to drain away.

The strap is made from a proprietary isoprene rubber that’s been developed to be both non-allergic and non-toxic. The compound recipe has been improved over the original ISOfrane material to provide even more durability and softness to rubber. What’s more, this was achieved without using silicon, which is known to attract dust particles.
