Designed with cold water adventures in mind, the Hydra Drysuit is made from High Density Neoprene compressed from 7mm to 4mm, providing warmth whilst maintaining freedom of movement. Fitted with high-end Apollo Bio-Dry Valves, YKK AQUASEAL® dry plastic zipper and the Hydpro Smooth Pro low pressure hose, the slimline cut of the suit means easier air management and all round supreme performance.

The Hydra Neoprene Drysuit is designed with cold water adventures in mind. With a close fitting, streamlined style, the Hydra is warm and flexible. High Density Neoprene (HDN) is used in critical areas throughout the suit. Compressed from 7mm to 4mm, HDN fuses the thermal protection of neoprene with a greater consistency of buoyancy throughout the dive. HDN is laminated with hardwearing fabric on the outside for excellent abrasion resistance, and smoother linings on the inside to increase comfort and aid donning.

Supratex linings protect critical wear areas in the crotch and underarms without limiting freedom of movement. Parts of the suit normally exposed to additional abrasion such as shoulders, waist and knees have a tough Durawear print.

Seams are fused and blindstitched before being taped on the inside and external plasma seams prevent abrasion from your equipment or environment.

Mobility is often the trade-off when opting for neoprene drysuits. The Hydra maximises this mobility with underarm gussets and the same composite YKK dry-zipper used in the Argonaut drysuit which is much more flexible and lighter in weight than the traditional brass zips. Our experience has shown that these zips, if looked after properly, will give extended, excellent performance.

Our 4mm compressed neoprene dryboots are fitted as standard. With double layer reinforcement, good grip and our ergonomic footbed, these boots are comfortable and reliable.

Fitted with Apollo Bio-Dry inflate and dump valves, the specification of this suit makes it your ideal companion for many cold water adventures. The Hydra is supplied with a Hydpro Smooth Pro low pressure hose. This braided hose is encased in a polyurethane coating which ensures low friction, flexibility and excellent durability even in cold temperatures.

Included with every Hydra is a 5mm Neoprene hood and Hydra Changing Bag.
