the Fjord 4.0 represents the next evolution in wetsuit innovation and performance development by deboer. building on the success of its predecessor, the Fjord 4.0 incorporates cutting-edge advancements...
why it feels tight: on dry land a right-size wetsuit feels firmly snug — like a handshake everywhere. In the water it eases and disappears. It’s only too small if you can’t breathe deeply or raise your arms overhead.
what buoyancy means: built-in float. This suit lifts your hips and legs so you stop dragging them — for most first-timers that’s worth more than months of training.
putting it on: dry skin, go slow, and use fingertip pads — never nails. Nail nicks are the #1 wetsuit injury.

get the fit right.
a wetsuit should feel snug on land and it eases the moment you're in the water. any looseness becomes a fold, and every fold scoops water and adds drag.
not sure on size? our fit team will confirm it from two photos before your first swim.
The moment you push off, the suit disappears. That's the whole point.

what swimmers say.
First open-water race in it and I forgot I was wearing a wetsuit. Hips sat higher the whole swim.

The shoulders are unreal — zero restriction on the catch. Came out of the water faster and fresher.

Sizing help over email got me into the right size first try. No fold, no flush, no drama.
