Waterproof SD Neoflex 7mm Semidry: The Ultimate Guide to Waterproof Semi Dry Wetsuits
For divers exploring cold and temperate waters, choosing the right exposure suit is essential for comfort, safety, and extended dive times. The Waterproof SD Neoflex 7mm Semidry is one of the most advanced semi-dry wetsuits available, combining the warmth of a drysuit with the flexibility of a premium wetsuit.
What Is the Waterproof SD Neoflex?
The Waterproof SD Neoflex is a high-performance waterproof semi dry wetsuit designed for divers who regularly explore cooler waters. Unlike traditional wetsuits, the SD Neoflex features advanced sealing systems and a flexible dry zipper that dramatically reduce water entry while maintaining exceptional comfort and mobility.
Its premium construction bridges the gap between a standard wetsuit and a drysuit, making it an excellent choice for divers who want enhanced thermal protection without switching to a full drysuit.
Waterproof SD Neoflex 7mm: Built for Cold-Water Performance
The Waterproof SD Neoflex 7mm is the flagship model in the Neoflex semi-dry range. It is engineered for divers who require reliable warmth during extended dives in cold environments.
Key Features
1. Neoflex Limestone CR Neoprene
The suit is constructed from premium 100% microcell limestone CR neoprene, offering superior insulation, flexibility, and durability compared with many conventional neoprene materials.
2. YKK Aquaseal Dry Zipper
One of the standout features of the Waterproof SD Neoflex 7mm Semidry is its ergonomic YKK AQUASEAL® #10 dry zipper, designed to minimize water ingress while remaining flexible and comfortable.
3. Extend Thermal Lining
The super-stretch thermal lining helps retain body heat and provides a softer, warmer feel during long dives.
4. Double Wrist and Ankle Seals
Smooth Glide Skin seals at the wrists and ankles work with corrosion-resistant YKK zippers to reduce water flushing and improve insulation.
5. Anatomical 3D Fit
Pre-bent arms and legs, along with ergonomic panel construction, improve flexibility and reduce diver fatigue.
Waterproof SD Neoflex 5mm: Is It Available?
Many divers search for the Waterproof SD Neoflex 5mm, but the SD Neoflex line is primarily offered as a 7mm semi-dry model.
If you need a thinner wetsuit for warmer conditions, Waterproof offers other wetsuit collections in 5mm thickness rather than a dedicated SD Neoflex 5mm. The SD Neoflex platform is specifically designed for maximum cold-water insulation.
Waterproof 01 Neoflex Overvest 5/7mm Women’s
The Waterproof 01 Neoflex Overvest 5/7mm Women’s provides extra warmth and comfort for your diving. Extremely soft and flexible due to the comfortable four-way super stretch neoprene. It features a front zip and a fixed 7mm ventilated hood.
O1 is part of our new Neoflex series, a great complement to wear over your regular wetsuit during cold dives. The inverted front zipper ends on the chest to achieve a closed-face seal without an annoying zipper. This solution makes the hood more comfortable and makes it easier to move the head.
The O1 vest has a detachable beaver tail with double Velcro locks. Thermal lining adds a softer, warmer, and more comfortable feel. Anti-slip surfaces at the shoulders and waist keep the BCD and weight belt in place.
The zipper is equipped with an EasyGrip puller for easy opening and closing. The elegant black colour looks great with all your other dive gear. O1 is manufactured with the best high-grade materials and technologies available for maximized durability and extended use.
