Shield 3/3mm Zipfree Fullsuit

Isurus Shield 3.3 Zipfree Fullsuit Wetsuit

The Shield 3.3 Zipfree Fullsuit delivers 4mm warmth in a lightweight 3mm wetsuit, giving you the perfect balance of insulation and unrestricted performance. Designed for surfers who want more warmth than the Shield 2.2 without sacrificing mobility, the 3.3 is built to keep you paddling faster, surfing longer, and feeling lighter in the water.

With Isurus’ signature Arms Up Design for zero shoulder restriction, this suit provides unmatched freedom of movement—ideal for long paddle-outs, heavy sessions, and surfers who struggle with shoulder fatigue. The improved zipfree entry offers a secure, watertight seal that’s still easier to get into and out of than traditional chest-zip or back-zip designs.

Life truly is better surfing in a thinner, warmer wetsuit.
