KEY INFORMATION
ION SEEK AMP 5/4 FRONT ZIP MEN 2027 - 5/4 mm Winter Fullsuit
What we like
- Graphene_Plush 2.0 on the back panel: This season's innovation for the Amp series is a lightweight, heat-conducting, and recycled lining. It works in conjunction with Hot_Stuff 2.0, which covers the rest of the body.
- Hot_Stuff 2.0 throughout the body: This is ION's most flexible, quick-drying thermal lining, made from recycled materials.
- Recycled Max_Flex: On the chest, shoulders, and neck, the Max_Flex outer lining provides 30% more flexibility, according to ION. This is precisely where you need movement for paddling and pumping.
- I_Foam Neoprene: ION chose this low-density foam, infused with oyster shell powder, for its insulation.
- Glued and taped seams: These are blind-stitched, with flexible tape on the entire interior. You'll find reinforced stress points and fused edges at the arms and legs.
- One-hand front zip: This new zipper opens to the left and closes to the right with a single hand. A soft cord adjusts the flap.
- Waterproof silicone prints on the front zip, arms, and legs minimize water entry.

DETAILED DESCRIPTION
What's new with the Seek Amp 2027
ION offers three Seek fullsuit series: Select for maximum warmth, Amp for elasticity, and Core as an all-rounder. The ION Seek Amp 5/4 Front Zip is the 5/4 front zip version of the Amp series, and ION is jumping directly from the 2025 to the 2027 collection. The innovation lies in the lining: the lightweight, heat-conducting, and recycled Graphene_Plush 2.0 covers the back panel, complementing the Hot_Stuff 2.0 that lines the rest of the body. ION states that both materials are made from recycled content.
Elasticity: Max_Flex, Eco_Stretch, I_Foam
The recycled Max_Flex outer lining covers the chest and shoulders. It also covers the neck. ION states it delivers 30% more flexibility and quick-drying properties. The rest of the wetsuit features Eco_Stretch, a fabric made from recycled nylon waste. Beneath these linings, the low-density I_Foam neoprene contains oyster shell powder, a filler ION uses for insulation. The shoulders are without a seam, and the reduced number of panels is immediately noticeable with your first arm movement.
Front zip, watertightness, and seams
Entry is via a diagonal chest zip, new this season. It opens to the left and closes to the right with one hand, and a flexible cord adjusts the flap. The back remains completely free for paddling and pumping. Silicone prints on the zip, arms, and legs limit water entry. The seams are glued and blind-stitched, taped with a flexible strip across the entire inner surface, with reinforced stress points. The arm and leg edges are fused. Reinforced drainage holes are located on the legs and chest. A key pocket with a loop, a replaceable cord, and separate leg straps are also included.
For what conditions
ION rates the Seek Amp 5/4 Front Zip for cold water conditions. This fullsuit moves effortlessly. On the Atlantic coast, this is the winter fullsuit, from December to March, with a hood, boots, and gloves as additional gear when the northeast wind sets in. For icy waters, the Seek Amp 6/5 Hood Front Zip adds an extra millimeter and an integrated hood, with the same construction. It comes in two colors: Black and Green Seek, which is a deep grey-green. Black is available in all fourteen sizes, while Green Seek is available in thirteen, excluding 46/XS. With twenty-seven variations, it offers the widest size range in the 2027 Amp lineup.

FAQ - ION SEEK AMP 5/4 FRONT ZIP MEN 2027
This wetsuit is for riders who kite from December to March on the Atlantic coast. They want a flexible winter wetsuit, not a restrictive one. For truly icy water or long, static sessions, the Seek Amp 6/5 Hood Front Zip has the advantage of its extra millimeter and its hood.
The front zip lets in less water and frees up the entire back for paddling. It requires some flexibility to get your head through the first time. The back zip is quicker to put on and take off, and it leaves the chest seam-free. ION offers the Seek Amp 5/4 in both versions. We recommend the Front Zip for those who spend long sessions in the water and want the least possible water entry.
The ION size guide higher on the page provides height and weight measurements for each size, along with chest measurements. Short cuts 25/MS to 28/XXLS have a wide bust on shorter legs. Long cuts 94/ST to 106/XLT have a slim bust on longer legs. The Green Seek color starts at 48/S. The ION photo model is 1.85 m tall and wears 52/L. A wetsuit should fit snugly when dry, without air creases. If you are between sizes, call us.
Rinse it with fresh water after each session, inside out. Dry it in the shade on a wide hanger. Never dry it in the sun or on a radiator. Never fold it wet in a bag. Close the zip before hanging it to avoid deforming the chest.
We are a Kite and Wing shop in Pornichet, on the Atlantic coast, and we also sell Surf gear. We ride all year in water that drops below ten degrees in February. We wear ION wetsuits before we sell them. If you have a doubt about the size or hesitate between two thickness options, call us or visit the shop.
