Bio Seal Wrist

The Apollo Bio-Seal Wrist is a stretchable thermal wrist seal system engineered to reduce water ingress and heat loss at the wrist interface of wetsuits and drysuits. Manufactured from high-elasticity sealing material, the Bio-Seal Wrist creates a close-contact barrier between the diver’s skin and suit cuff, significantly reducing flushing and improving overall thermal efficiency.

Designed for military, commercial and professional diving applications, the Bio-Seal Wrist enhances cold-water performance and diver endurance during extended maritime operations. Its low-profile and flexible construction ensures compatibility with gloves and exposure systems without restricting dexterity or circulation.
