The Patagonia Regulator® 4/3 Full Wetsuit is a technical full suit designed with a focus on warmth, stretch and unrestricted movement.

The suit is made from 85% Yulex® natural rubber and 15% synthetic rubber by polymer content. The natural rubber comes from Forest Stewardship Council® (FSC) certified sources through Preferred by Nature™.

Instead of traditional neoprene, the suit uses Yulex® natural rubber. Its internal and external face fabrics are made from NetPlus® recycled nylon produced from recycled fishing nets. The fabrics are solution-dyed using a process that uses no water during dyeing.

The unique U-zip entry makes the suit easier to put on and take off while helping reduce flushing. It uses a YKK® #5 stretch-coil zipper with an extended custom pull for easy access.

The Formfitting construction is designed to provide maximum mobility from the upper body through to the ankle cuffs.

All seams are triple-glued and blindstitched, with internal stretch seam tape for reinforcement. The linings are laminated using water-based, solvent-free AquaA® adhesive.

External rubber wrist and ankle gaskets provide a secure fit and help reduce water entry.

An easy-access key loop provides convenient storage for a key while in the water.

Patagonia recommends this suit for water temperatures of approximately 10–16°C, although actual warmth depends on several factors including activity level, wind and individual sensitivity to cold.
