The Gill Dynamic Youth Long John is built for young sailors and watersports athletes who want to move freely, stay warm and push their limits on the water. Designed for performance and comfort, it delivers reliable insulation and flexibility in changing conditions.
Made from 3mm BIO foam – a next-generation natural rubber blend created from renewable materials – this non-neoprene wetsuit provides excellent warmth and impact protection without relying on oil- or limestone-based rubber. The closed-cell construction traps heat close to the body, helping young athletes stay comfortable during long sessions on the water.
A YKK front zip allows for easy on and off, while the 4-way stretch fabric ensures unrestricted movement for sailing, paddling or training. Reinforced Di-Guard panels at the seat and knees add extra durability where it’s needed most, standing up to every tack, launch and wipeout.
Soft, flexible and responsibly made, the Dynamic Youth Long John combines sustainable materials with high-quality construction — keeping young riders focused on performance, not the cold.
Ideal for: Youth sailing, paddle sports, training and multi-sport watersports use
