Clark Full Wetsuit - Reef 4/3mm
Clark 4/3mm is designed for cold water and serious sessions. Full sleeves, full-length legs, and a thermal lining through the chest and back panels deliver the warmth you need to stay in the water longer without compromising movement or comfort.
Made with Yamamoto limestone neoprene, sourced from calcium carbonate, not petroleum. Softer, lighter, and more heat-efficient than conventional neoprene. Glued and blind-stitched (GBS) seams minimise water entry and maximise thermal retention in cold conditions. A back-zip entry makes it easy to get in and out before and after sessions.

Warmth & conditions:
A 4/3mm wetsuit is ideal for water temperatures between 50–58°F (10–14°C). This covers cold coastal conditions — California winter, Pacific Northwest, northern Europe, New Zealand winter.
Need less warmth? → Clark 3/3mm (58–66°F / 14–19°C) · Clark 2/2mm (64–72°F / 18–22°C). Need more warmth? → Clark 5/4mm (below 50°F / below 10°C)
Choosing your size
Clark fullsuits are designed to fit snugly for warmth and performance.
- Choose your usual wetsuit size
- 2/2mm: very stretchy — a close fit is recommended
- 3/3mm, 4/3mm & 5/4mm: slightly firmer — if between sizes, consider sizing up
- A snug feel when dry is normal and softens once wet
Choosing your thickness
Clark is available in 2/2mm, 3/3mm, 4/3mm, and 5/4mm, offering progressive warmth.
- 2/2mm → mild water, warmer sessions
- 3/3mm → cooler water, everyday use
- 4/3mm → 50–58°F (10–14°C) — cold water, winter surf, GBS seams and thermal lining
- 5/4mm → very cold water, long winter sessions
Choose lighter thicknesses for flexibility, thicker options for maximum warmth.

Need help?
If you’re unsure about size or thickness, our team is happy to help.
Which thickness is the Clark 4/3mm for?
The Clark 4/3mm is designed for water temperatures between 50–58°F (10–14°C). It provides serious warmth for cold water, winter surf, and extended sessions where staying warm is the priority.
What is Yamamoto neoprene?
Yamamoto neoprene is made from calcium carbonate derived from limestone, not petroleum. It is softer, lighter, and more flexible than conventional neoprene, and has a lower environmental impact. Abysse uses Yamamoto #39 limestone neoprene across the Clark range.
What is ECOPRENE?
ECOPRENE is Abysse's proprietary material system combining Yamamoto limestone neoprene with recycled bottle linings. It is designed as a lower-impact alternative to petroleum-based wetsuits without compromising warmth or flexibility.
Does the 4/3mm Clark have thermal lining?
Yes. The Clark 4/3mm features a thermal internal lining through key body panels to maximise warmth retention during cold water sessions. Combined with GBS seams, it is designed for extended time in cold conditions.
What seams does the 4/3mm use?
The Clark 4/3mm uses glued and blind-stitched (GBS) seams. GBS seams create a watertight seal that minimises water entry and improves thermal retention during cold water and winter surf sessions.
Does Clark feel restrictive in thicker versions?
Clark is designed to maintain comfort and mobility across all thicknesses. High-movement areas, shoulders and arms, remain flexible even in the 5/4mm.
How do I care for my Clark wetsuit?
Rinse with fresh water after every session. Dry away from direct sunlight. Close the Velcro tabs before storing to protect the lining and seams.
Is Clark suitable for activities other than surfing?
Yes, Clark is designed for surfing, SUP, kitesurfing, windsurfing, wakeboarding, foiling, open-water swimming, snorkelling, and scuba diving.
The Clark wetsuit is built with ECOPRENE, Abysse's material system combining premium Japanese neoprene with recycled fabrics.
