Note: Breathable tri-laminate drysuit are not suitable for diving, but because of its light and low-cost characteristics, many brands have launched ultra-lightweight travel drysuit (equipped with inflation valve and exhaust valve) made based on breathable tri-laminate fabric, but it can generally only be used for diving at a depth of no more than 10 meters. In fact, there are also lightweight options for butyl tri-laminate fabric, but the price is more expensive than breathable tri-laminate fabric.

Drysuits Leaking and Maintenance Problems:

All our drysuits are tested for pressure leaks in a test pool before leaving the factory to ensure that the drysuits do not leak when shipped, but the harsh transportation environment (Abnormal collision and squeezing) and incorrect storage (abnormal squeezes) occasionally cause water leaks (rarely found).

Unless drysuits are rarely used, water leakage is practically impossible to avoid. Due to the use environment, strength, habits, matching, cleaning and storage methods and occasions, component life and aging and other factors, many drysuits are used after dozens to hundreds of times, it will happen water leaks.

Leaking does not mean that drysuits can no longer be used, most of the water leakage conditions can be repaired. We provide warranty services (quality problems) and repair services (use problems). Unless the aging material has no repair value, everything else can be repaired.

Under normal circumstances, common simple problems are recommended to customers to repair by themselves (such as small leaks, etc.) to save time and transportation costs. We have optional repair kits when we leave the factory, and various repair kits are also available on the market. If there is a big problem, it is recommended that the customer return to the factory for repair (for example: replacing the waterproof zipper, repairing a large break, etc.).
