Women's Sizing

Size chart based on the current Sooruz pattern. Older year codes (E22, H22, H23 etc.) used very similar sizing but cut and stretch may vary slightly — Sooruz sizes typically run slim through the chest, so if you're between sizes, sizing up is usually the right call. For sizing advice, call us on 01492 588001.

About Sooruz

Sooruz is a French watersports brand founded in 1999 in La Rochelle, building wetsuits and accessories designed by riders for riders. Innovation and environmental responsibility sit at the core — Sooruz pioneered Oysterprene® neoprene (made using recycled oyster shells and bio-based components), alongside recycled fabrics, water-based glues, and circular initiatives for used wetsuits.

The Guru+ is Sooruz's warmth-focused flagship — sitting above the Guru Pro in the warmth direction. Where the Guru Pro offers premium flex and warmth in a balanced package, the Guru+ trades a small amount of flex for additional Storm Dry lining coverage and warmth retention. The right choice for cold-water-focused paddlers and surfers.
