Shield 3.3 Zipfree Wetsuit Description

The same Arms Up Design | Zero Shoulder Restriction paddling as the Shield 2.2.  But with an extra mm of warmth. Giving you 4 mm warmth in a 3 mm wetsuit. So you can surf thinner and longer.

It paddles like a dream. It's the easiest wetsuit to get into and out of. The “Arms Up” design provides you with virtually “zero restriction” through the chest and shoulders. If you are tired of sore and aching shoulders after a session, than take a look at the Isurus Zipfree line.

The Zipfree entry has been improved for a better water tight seal.  Still easier to get into and out of than chest zips or back zip wetsuits.

Life is just better surfing in a thinner, warmer wetsuit. Skeptical? Ask out in the line up.

At Isurus, our passion is to build world-class wetsuits that stand up to the harshest conditions the ocean might offer.

Living and surfing in and along the California coast, a frequent topic of conversation was just how much wetsuit innovation had stagnated and quality had deteriorated. It is about designing a wetsuit that improves surfer performance. Click for more about Isurus.
