Seek Amp 5/4 Front Zip 2025 Wetsuit

Performance & Feel

The Seek Amp sits at the top of ION's wetsuit range, built around being flexible and warm. The 5/4 is ION's full cold-water suit. A continuous section of Max_Flex neoprene across the chest, shoulders and arms, front and back, together with the seam-free Sweep_Cut shoulder, means there's a lot of flexibility. The lower-density foam adds more stretch again and, just as usefully, holds that stretch as the suit ages.

With 5mm through the core and 4mm in the arms and legs, the 5/4 has serious warmth for cold-water sessions. 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 covers a larger area for quick-drying warmth. The rest of the suit is lined with Silk_Stuff 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.
