I don't remember ever riding a jet ski in the winter, and I've only worn this once, so it might be unused. The rubber parts around the neck, both hands, and both feet seem to be fine, but I haven't done a water resistance test, so please purchase with no claims and no returns. A G FORCE drysuit from mobby's, known for its excellent waterproofness, with socks. Perfect for marine sports (PWC, jet ski, boat fishing). The total length was approximately 165cm when laid flat (excluding socks). - Brand: mobby's - Color: Black - Type: Drysuit - Features: Excellent waterproofness and durability - Model Name: G FORCE Front zipper type For jet skis and marine jets Thank you for viewing.
