The Waterproof W5 3.5mm men’s wetsuit is a full-length scuba suit for divers who want a lighter neoprene layer with useful storage and easy dressing features. Its shaped cut and flexible CR neoprene let you bend, reach and swim naturally, while glued and blind-stitched seams help limit water exchange.
Features and benefits
- 3.5mm microcell limestone CR neoprene: a flexible insulating layer for conditions where a lighter full suit suits your needs. It retains full arm and leg coverage without the bulk of a thicker wetsuit.
- Shaped for movement: pre-bent arms and legs follow the diving position. Wave Flex panels at the joints reduce resistance when bending your limbs.
- Back zip and zipped cuffs: a YKK #10 Vislon main zip provides a wide opening, while wrist and ankle zips make it easier to pass your hands and feet through the suit.
- Gusseted neck comfort zip: open it on the surface to ease collar pressure, then close it before diving. The moulded collar tab allows further adjustment.
- Integrated hip storage: two stretchy pockets provide space for small dive essentials. Drain valves release water and internal loops allow suitable items to be secured.
- Protection where the suit gets used: Duratex reinforcement at the seat, elbows and knees helps resist abrasion without making the whole suit stiff.
- Computer retention: anchors and polyurethane anti-slip print on both arms help keep a wrist computer in position as the neoprene compresses.

Gear Care and Washing
After every use, rinse the suit inside and out in cool fresh water to remove salt, chlorine, sand and other residue. Gently hand wash when needed using mild soap or a cleaner specifically authorised by Waterproof. Rinse thoroughly after washing.
Let both sides dry completely in the shade with good airflow. Support the suit on a broad wetsuit hanger, or drape it over a wide support to avoid stretching the shoulders. Store clean and dry in a cool place away from direct sunlight, heaters, hot cars and sharp folds.
Rinse sand and salt from the zip and close hook-and-loop tabs so they cannot snag the fabric. Never force a jammed zip. Use only the zip maker’s specified lubricant and storage position; ordinary wax or silicone is not suitable for every specialist zip.
Do not machine wash, tumble dry, iron, bleach or use solvents. Follow the supplied care instructions for this suit and its zip before using any cleaning or maintenance product.
