Freedivers Marseilles Weightbelts are a great choice when it comes to durability, quality and flexibility. These are made from synthetic rubber weight belt for longevity - guaranteed to outlast rubber weightbelts for UV and ozone resistance.
These dive belts are super durable and light weight, with non-reflective, glass re-inforced nylon buckle. Belts have enough elasicity to adjust in size as your wetsuit compresses with depth. Synthetic rubber meterial helps to grip to the wetsuit, reducing sliding around and slipping during ascent and descent.
To increase elasticity, simply stand on the buckle and stretch belt as hard as you can. This changes the molecular structure of the synthetic rubber material and provides greater stretchiness.
