Demon United Zero RF D3O® Ski & Snowboard Knee Pads

The everyday knee pad you put on and forget — recycled D3O® smart foam, no bulk, fits under anything.

Recycled D3O® RF foam and thick comfort foam inside a soft neoprene body, with silicone grip bands and soft-touch Velcro that lock it in place. Slim enough to disappear under any pants, and smart enough to take the hit you didn't see coming.

Features

Recycled D3O® RF smart foam — Non-Newtonian foam that moves with your knee through crouches, jumps, and edge catches, then stiffens on impact to absorb the hit and resets. Built from 100% recycled D3O® Zero material.
Thick comfort foam layer — Cushions the constant low-level knocks of all-day park laps and resort riding, layered under the D3O®.
Soft neoprene body — Wetsuit-style neoprene conforms to your knee and flexes through every degree without bunching, twisting, or riding up — breathable enough for long sessions.
Stay-put fit — An elastic Velcro closure plus internal silicone grip bands hold the pad in place without pressure points or a circulation-cutting squeeze — no reaching down mid-run.
Low-profile — Layers cleanly under any ski or snowboard pants.

Frequently asked questions

Yes — low-profile under-pant wear is the entire point of the Zero RF. The soft neoprene body sits close to the leg without creating a visible pad outline under outerwear, and the slim D3O RF and comfort foam stack doesn't add bulk at the knee cap the way hard-shell pads do. Most riders wear them directly over a base layer under their ski or snowboard pants and report them as easy to forget about once they're on. Size according to the Demon chart — a pad that's too large will bunch under the pants and create exactly the bulk you're trying to avoid. When properly sized, they should feel snug but not compressive, with no bunching at the top or bottom edge.

Two different pads for two different jobs. The Zero RF is the everyday pad — recycled D3O RF foam inside a soft neoprene body, slim enough to disappear under any pants, light enough to forget about between crashes. It's built for riders who want reliable daily knee protection without armor bulk. The Hyper X V7 is the full-send option — D3O Range (a higher-performance grade), a ballistic Kevlar front shield that resists abrasion from rails, concrete, and ice, and a triple-layer construction built for riders taking serious hits in the park, on technical MTB terrain, or anywhere the consequences of a slam are real. If you're cruising, progressing, or just want coverage every day — Zero RF. If you're sending it and need the protection to match — Hyper X V7.

The Zero RF uses a two-part retention system specifically designed to prevent the mid-run sliding that makes most riders give up on knee pads. Internal silicone grip bands run against the leg and create passive friction hold — they lock the pad against the skin without compression, so the pad stays put through crouches, jumps, and hard landings without you doing anything. The soft-touch Velcro closure at the top adds a secondary mechanical lock, adjustable to your leg circumference, without the scratchy bite of standard hook-and-loop closures. If you've ditched other knee pads because they ended up around your ankle by noon, the grip band system is the fix.
