Seek Amp 4/3 Front Zip 2024 Wetsuit

Performance & Feel

The Seek Amp sits at the top of ION's wetsuit range, built around one thing above all: flexibility. The 4/3 is its cold-water version, the same flexibility-first suit with the extra warmth for autumn, winter and spring. Fewer panels, a continuous run of neoprene across the front and back, and the seam-free Sweep_Cut shoulder mean there's a lot of flexibility. For 2024 the foam density is more consistent, which adds more stretch again and, just as usefully, holds that stretch as the suit ages.

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 lightweight 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 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.
