Simpel Men's 4/3mm Hooded Wetsuit

The Development Edition runs Yamamoto #39 and #40 limestone rubber throughout. #39 brings exceptional warmth and buoyancy through its closed-cell structure. #40 adds a lower elastic modulus for less resistance in the paddle and cleaner return to shape. A layered wetsuit performance profile across warmth, float and flex.

The back panel and hood feature our hydrophobic Windshield laminate. Its water-repellent outer surface helps shed water and reduce wind chill across exposed areas. Unlike conventional smoothskin materials, Windshield can also be stitched, allowing us to reinforce the seams for improved durability without sacrificing flexibility. A considered combination of warmth, performance and construction designed to last.

Yamamoto SCS tape reinforces all upper body seams internally. Made from thin, flexible rubber with Yamamoto's Super Composite Skin surface treatment, it provides additional reinforcement without the bulk of heavier seam materials. The smooth SCS surface has low friction against the skin and dries quickly. Its high-stretch construction reinforces the seams without compromising flexibility across the shoulders and upper body.

Lightweight, super-stretch lower leg linings by design. We've selected a soft, flexible lining that runs from behind the knees to the ankles, reducing resistance and allowing greater freedom of movement. It's a small detail that makes a noticeable difference. All the warmth you'd expect from a 4/3mm, with the flexibility and feel of a lighter suit.

A new floating bib template offers increased mobility and symmetrical feel through the shoulders, reduces material across the upper chest at the point of greatest restriction through a paddle stroke. Combined with the easy synch Bib cord, it keeps the seal tight while returning range of motion across the chest and shoulders.

We've redesigned the chest toggle with a double bungee system for a more secure seal. The dual cords distribute tension more evenly across the bib, helping keep it firmly in place and reducing water entry. The adjustable cord lock and extended pull tab make it easy to tighten or release, even when wearing gloves. A small detail that makes a difference in cold water.

Yamamoto limestone neoprene throughout. #39 for warmth and float. #40 for lower-resistance stretch. Lighter, more flexible and longer lasting than petroleum-based neoprene, with closed-cell structure that holds heat independently.

Our hydrophobic Windshield laminate on the back panel and hood sheds water, reduces wind chill and allows reinforced stitching for improved seam durability.

Integrated hood with thermal lining throughout. Revised facial opening for improved peripheral vision and increase comfort in the water.

Durable, abrasion-resistant knee pads provide protection in high-wear areas while maintaining flexibility and allowing a natural range of movement through the knees.

Flexible, lightweight outer jersey for durability, comfort and performance.

Soft, flexible liquid seals at the wrists and ankles sit comfortably against the skin, helping reduce water entry and flushing to maintain warmth in cold water.

Our rubber panels are glued together and reinforced with blind stitching. The stitching penetrates only partway through the rubber, helping reduce water entry while maintaining seam strength, flexibility and warmth.

Upper body seams reinforced internally with Yamamoto SCS tape. Holds the seam without restricting the neoprene's natural stretch.

Lower body seams taped with Xtend Thermal and tape for seam strength and warmth continuity from thigh to ankle.

Easy neck entry with updated chest toggle for fast one-handed cinch and release.

Our new floating bib design follows the natural movement of your upper body, providing greater flexibility and comfort through every paddle stroke.

Thick EVA foam peak consistent with the Simpel Cold Water Collection. Protection from spray, rain and sun.

Durable metal zipper with a locking mechanism designed to help prevent accidental opening while the wetsuit is worn.

Lightweight and fast-drying, the recycled outer jersey adds durability and comfort without the weight.

High-pile internal lining from chest to ankle traps warmth and dries fast between sessions.
