JOBE Knox Floatable Glasses — Black Polarized
The JOBE Knox are purpose-built watersport sunglasses that tick every box for kiteboarding, foiling, SUP, and time on the water. The rubber frame is genuinely floatable — drop them off your board and they’ll be waiting on the surface when you swim back. Polarised UV-400 lenses cut the glare off flat water so you can actually see what’s around you, and extended side coverage blocks peripheral wind and sun during high-speed runs.
Lightweight at 180g with an adjustable flexible strap that locks them to your head, the Knox are designed to stay on through wipeouts and come off easily between sets. One size fits all.

Construction
The Knox frame is moulded from rubber that sits lighter than water, so the glasses float rather than sink when dropped. The polarised lens filter blocks horizontally-reflected light — the type that bounces off flat water and causes the squinting glare familiar to any paddler or kiter. UV-400 certification means full-spectrum protection across the entire ultraviolet range, not just the visible end. The flexible rubber strap replaces the rigid ear hooks of standard sunglasses, conforming to your head shape for a secure, comfortable fit during active use.
Why We Recommend It
If you’re spending time on the water — kiting, foiling, SUP, or just out on a boat — you need sunglasses that won’t disappear to the bottom if they come off. The Knox solve that problem without sacrificing lens quality. The polarised lenses make a genuine difference on the water versus standard tinted glass, and at under $70 they’re an easy addition to any kite bag or board bag.
