SISSTR 7 Seas 5/4 Chest Zip Wetsuit - Black - UK 10

This 5/4mm suit is optimized for cold water conditions between 44°F and 53°F (8°C - 12°C).

Limestone-based neoprene is a synthetic rubber derived from limestone rather than petroleum, offering higher heat retention, flexibility, and a lower environmental footprint.

No, never machine wash your wetsuit. The agitation and heat will destroy the neoprene and the stitching. Only use fresh water and hand washing.

The suit should feel like a 'second skin' with no large air pockets or bunching at the joints. It should be snug, but not so tight that it restricts your breathing or full range of motion.

Chest-zips provide a much better seal against water entry at the neck compared to back-zips and allow for more flexibility in the back panel for paddling.

Yes, it includes an easy-access key cord located inside the suit for secure storage.

Ensure the suit is pulled completely up to your hips and waist before attempting to put your arms through the sleeves. Use a plastic bag on your feet if struggling to slide them through the lower legs.

Check that the chest-zip flap is laid flat against your chest and the toggle is fully cinched. Ensure cuff seals are sitting flush against your skin without folds.

This is often caused by salt buildup. Soak the suit in fresh water for 30 minutes to dissolve the salt and ensure it is stored away from heat sources.
