ION Seek Core 5/4 Frontzip 2026 Wetsuit

Revolutionary eco-friendly 5/4 winter wetsuit from ION

The Seek Core 5/4 Frontzip 2026 is the game changer you've been waiting for! ION has completely renewed their Core line and this wetsuit proves that sustainability and top performance can go perfectly together. With brand new eco-friendly materials and smart innovations, this is the most advanced winter wetsuit in its class.

The secret lies in the revolutionary Natural Rubber foam. This neoprene-free rubber is made from oyster shell powder, soybean oil and eco-carbon black. Sounds crazy, but the result is phenomenal! You get the same insulation and flex as traditional neoprene, but without the environmental impact. With 5mm thickness on the torso and 4mm on arms and legs, you have optimal warmth and freedom of movement.

On the inside you'll find two amazing upgrades. The new Hot Stuff 3.0 lining has thicker loops that trap more air for better heat insulation, crucial for cold water sessions. This lining is made from recycled nylon and is the stretchiest thermal lining in the entire ION range! On the lower legs and sleeves, the improved Silk Stuff 2.0 provides ultimate comfort on your bare skin.

The Maki Tape 2.0 seams are a technical masterpiece. This super elastic neoprene tape reinforces the seams on the inside at crucial spots. Glued and blind stitched to keep water out, but with maximum flex. Equipped with practical features like drain holes, this wetsuit protects you against incoming water, even during heavy crashes. The frontzip closure on the chest provides extra freedom of movement and keeps water out better than a traditional back zip.

The coolest feature is the four unique water defenders, two per leg. This patented ION innovation prevents your wetsuit from riding up and keeps you extra warm, without needing straps.

The ION Seek Core 5/4 Frontzip 2026 Wetsuit is your winter wetsuit for cold water sessions. Extra warm, comfortable, eco-friendly and ready for every winter session!
