Seek Amp 4/3 Front Zip 2026 Wetsuit

ION Seek Amp 4/3 Front Zip Wetsuit

The ION Seek Amp 4/3 Front Zip is the most flexible suit ION makes and you feel it the moment you put it on. For 2026 the Limestone Neoprene with the inclusion of Oyster Shell in most of the suit has changed in density, giving it even more stretch and holding that stretch for longer. This includes Max_Flex Concept across the chest as well as the arms and shoulders. Minimal-panel cut and Hot_Stuff 2.0, the stretchiest thermal lining in ION's range, makes for a very comfortable fitting suit. The 4/3 is the colder water thickness but depending on how you feel the cold, the suit will keep you warm from spring through to autumn.

Our Test Team Thoughts

"We've found the Seek Amp 4/3 is as warm as some 5/4 suits from other brands, and as warm as ION's own 5/4 Element. One of us is happy riding his 4/3 Seek Amp right up to the Christmas break each year."

Performance & Feel

The Seek Amp sits at the top of ION's wetsuit range, built around one thing above all: flexibility. Fewer panels, a continuous run of Max_Flex Concept neoprene across the chest/shoulders/arms and a seam-free Sweep_Cut shoulder mean there's a lot of flexibility. For 2026 the Limestone Neoprene with the inclusion of Oyster Shell in most of the suit has changed in density, giving it even more stretch and holding that stretch for longer.

With 4mm through the core and 3mm in the arms and legs, the 4/3 has the warmth for cold water, and the Seek Amp's linings make the most of it. The i_foam neoprene traps more air in its structure than standard foam, Hot_Stuff 2.0 lines most of the suit with ION's plushiest, stretchiest thermal lining, and the Plasma_Plush 2.0 panel now covers a larger area in the torso for quick-drying warmth. Silk_Stuff lines the rest of the suit and feels soft next to the skin. The neoprene also takes in Oyster Shell Powder and Eco Carbon Black as part of a more environmentally considered manufacture.

The front zip seals across the chest. Dry_Grid lining absorbs up to 30% less water, so the suit stays lighter and chills you less by evaporation. Seal_Tite cuffs keep water ingress down.
