The Typhoon Hypercurve Drysuit reinvents the design and shape of drysuits, using the 3D panel to fit the zip into the back of the suit. This design significantly reduces the stress in the fabric at either end of the zip, meaning it lasts much longer. Additionally, this style of zip improves the overall shape and comfort of the suit, and makes it easier to get on and off than other styles. As with all Typhoon drysuits, the Hypercurve is built to last, qualifying it for a 3-year manufacturer warranty. The Typhoon Hypercurve 4 uses Typhoon’s quad-ply breathable fabric for extreme waterproof durability, with reinforced knees and seat to increase the lifetime of this suit. All of our Typhoon Hypercurve drysuits come with an underfleece to provide additional warmth and insulation, meaning you can stay on the water for longer.
