Leatt 3DF 3.5 Kidney Belt — CE Certified Lumbar Protection

Your lower back is the zone you forget about, until you can't. The Leatt 3DF 3.5 kidney belt protects your kidneys and lumbar region with Leatt's 3DF AirFit impact foam: soft and flexible all day, firm when it counts. Certified to EN 1621-2 Level 1 for lumbar protection, it checks the safety box without adding bulk.

The thermoformed 3D structure builds ventilation channels directly into the foam, keeping air moving even when you're pushing hard. Wide elastic bands hold the belt in place without digging in, and the double-strap closure lets you dial in the fit for your build and riding position.

It disappears under your jersey, until the moment it doesn't have to.

Sports DRC Expert tip
Wear this belt directly over your base layer, under your jersey or jacket. For riders in pants without built-in lumbar protection, it's the simplest way to cover the exposed gap between a back protector and the pant waistband.
