About Sooruz
Sooruz is a French watersports brand founded in 1999 in La Rochelle. 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 Guru Pro 4/3 is Sooruz's top performance 4/3 — balanced warmth and stretch, with the newest Ö8 Oysterprene foam. For UK, this is a solid spring / autumn / early winter suit. If you ride through deep winter, step up to the Guru+ 5/4/3 U-Zip or the hooded Guru+ Hood 6/5/4 U-Zip. 01492 588001 for sizing.
