NEX Underwater Products Leatherback Bladder

Better Trim Starts with Better Wing Design

A wing isn't just there to provide lift.

Where that lift is distributed can change the way your entire system feels in the water.

The NEX Underwater Products Leatherback Bladder brings together a distinctive Golden Ratio-inspired wing design with your choice of 1000D Cordura TPU or Knight Shield construction, giving divers options for both performance and durability.

Developed in collaboration with Knight Divers in Malta, the Leatherback wing is designed to provide superior trim and comfort throughout the dive, from floating at the surface to maintaining position underwater.

Designed Around the Golden Ratio

The Leatherback isn't simply another traditionally shaped wing.

Knight Divers developed the wing using a design based on the Golden Ratio, with the goal of creating better trim and comfort across a wide range of diving conditions.

The shape affects how buoyancy is distributed around the diver, helping create a system that works differently at the surface and underwater.

Because where the air goes matters just as much as how much lift you have.

Head Up at the Surface

Waiting at the surface shouldn't mean fighting your BCD to stay comfortably upright.

The Leatherback design provides exceptional lumbar support at the surface, helping the diver maintain a comfortable head-up position before descent.

Whether you're waiting for your buddy, preparing to descend or simply spending a few extra minutes on the surface, that additional support can make a noticeable difference.

Get Underwater - And Get Horizontal

Once you descend, the job changes.

Now you want trim.

The tapered upper portion of the Leatherback wing is designed to help prevent excessive buoyancy around the diver's upper body from pushing the head upward.

That helps support a more natural horizontal position and assists with buoyancy control throughout the water column.

Surface comfort when you're waiting to descend.

Trim and balance when it's time to dive.

Choose Your Armor

NEX offers the Leatherback Bladder in two construction options.

1000D Cordura TPU

The Cordura version uses Cordura 1000 TPU, a thermal polyurethane-coated material that provides a rugged option for divers looking for durability without stepping up to the Knight Shield construction.

Knight Shield

Then there's Knight Shield.

NEX describes Knight Shield as military-grade and bulletproof, creating a premium option for divers who want an exceptionally rugged exterior for their Leatherback wing.

For divers who are tough on equipment, explore demanding environments or simply want the highest level of protection NEX offers for the Leatherback, Knight Shield is the option that demands attention.
