About the U-Zip
The U-Zip is Sooruz's new wetsuit entry system — a curved YKK SOFLEX® zip replacing the traditional straight chest zip. It gives you a wider entry (easier on/off), a curved path across the chest that flexes better when paddling, and a tighter seal that reduces flushing on duck dives and wipeouts. It's discreet and almost invisible from the outside — the suit looks cleaner than a traditional chest-zip. Sooruz's own team say it's their new preferred entry system going forward.
About Sooruz
Sooruz is a French watersports brand founded in 1999 in La Rochelle. They were one of the first to put sustainability at the centre of wetsuit design — Oysterprene uses oyster-shell powder as a limestone replacement in the neoprene foam, cutting the petroleum content substantially. 25+ years in, their suits are worn and tested by a team of serious European surfers and wind-sport athletes.
Honest advice from us
The 5/4/3 is the right pick for UK autumn/spring surf, or for anyone running warm who wants a bit less bulk than a 6/5/4. The W6 refresh brings the new U-Zip plus Storm Dry 2, Dry Cuffs and the Black Diamond back — this is the most feature-rich non-hooded suit Sooruz have made. If you need a hood for proper winter sessions, step up to the Guru+ Hooded 6/5/4 U-Zip. 01492 588001 for sizing advice.
