FAQ

▸ What is the difference between the Infiniti 5/4mm and 4/3mm?

The 5/4mm is built for colder water between 6–12°C, where the additional thickness provides meaningfully more thermal protection than a 4/3mm. While slightly less flexible than the thinner model, Channel Flex and Nanoprene Lite ensure the 5/4mm remains one of the most mobile cold-water suits in its class.

▸ What is Radiant Rebound technology?

Radiant Rebound is XCEL's metallic interior lining that works in two directions — blocking cold water from penetrating the suit while simultaneously reflecting the wearer's own body heat back inward. The result is a noticeably warmer experience during long cold-water sessions without adding bulk or stiffness.

▸ What does the magnetic zipper closure do?

The semi-dry magnetic closure allows for a quick, one-handed seal that snaps securely into place — making suiting up faster and more reliable than traditional zip toggles. It also creates a tighter water-resistant closure to reduce flushing at the entry point.

▸ Is the XCEL Infiniti 5/4mm suitable for kiteboarding and windsurfing?

Yes. The Channel Flex exterior and engineered anatomical fit are specifically designed to support unrestricted upper body movement — making the Infiniti 5/4mm equally capable for paddle-based and wind-driven water sports in cold-water conditions.
