Part of the Gul Flexor collectionView full collection

The Gul Flexor 5/4mm Yulex Junior Steamer is designed to keep young surfers warm, flexible and comfortable while reducing environmental impact. Built using YULEX® FSC® and PEFC® certified natural rubber, this wetsuit provides reliable insulation and stretch while supporting more sustainable materials compared to traditional neoprene.

Engineered for growing riders, the Flexor combines durable construction with flexible panels to allow easy paddling, swimming and movement in the water. RevoFit 3D pattern technology creates a comfortable, ergonomic fit that moves naturally with the body, helping junior surfers stay confident and comfortable during every session.

ThermoSpan thermal lining improves warmth without adding bulk, while the Micro2Flex internal lining offers a soft feel against the skin and dries quickly between sessions. Blindstitched seams combined with G-Tape internal taping in key stress zones enhance durability while helping reduce water entry.

The S-Lock flush barrier back zip entry makes the wetsuit easy to get on and off, while reducing flushing when in the water. A PK stainless steel blackout zipper ensures reliable performance in saltwater environments. Pro GlideSkin collar and S-Seal wrist and ankle cuffs help keep cold water out and warmth in, while reinforced PowerTex4 knee pads protect high-wear areas during kneeling and pop-ups.

Ideal for:

  • Kids learning to surf
  • Bodyboarding and beach days
