Demon United Zero PLUS RF D3O® Unisex Ski/Snowboard Vest
Demon United Zero RF D3O® Ski & Snowboard Vest — EN-Certified Back Protection. Recycled D3O®. Fits Under Anything.
The Zero RF Vest is the back protection you put on and forget about — until it matters. Recycled D3O® RF foam and RZ Labs certified back guard team up for full-back coverage that complies with EN1621-2 Level 1, wrapped in a construction soft enough to wear under any jacket all day. Spine protection that doesn't ask anything of you except to wear it.
Back injuries end seasons. Spine injuries end careers. And yet most riders go out every single day with nothing between their back and the ground. The Zero RF Vest is built for those riders — the ones who want real back protection without the bulk, the heat, or the wrestling match of getting a full impact top on and off at the lodge.
The protection stack starts with a RZ Labs Foam back guard certified to EN1621-2 — a durable, pliable panel that runs the length of your spine, absorbing and dispersing the force from edge catches, backward slams, and the kind of flat-back landings that nobody plans for. RZ Labs foam is engineered for repeated impact absorption across a full season without losing structural integrity — this isn't padding that compresses once and calls it done.
Layered with recycled D3O® RF foam as the soft underlay, the back zone gets the combination of smart impact response and all-day pliability that defines the Zero RF lineup. D3O RF rate-stiffens on impact and returns to its flexible state instantly — no stiff panel locked against your spine between runs, no restriction through the full range of back movement you need for riding.
At the chest and ribs, soft air foam padding provides lightweight coverage and comfort without adding the bulk that makes full impact tops feel like armor. This is the vest for riders who want spine protection as their priority and a bit of frontal cushioning to go with it — not a full six-pad impact system.
Available in youth through adult sizing, it layers clean under any ski or snowboard jacket without a visible outline or movement restriction in any direction. Built from recycled D3O® Zero foam, it's back protection with a conscience. The mountain you're riding on deserves the same care you give your spine.

The RZ Labs back guard is a durable, pliable panel certified to EN1621-2 Level 1 — engineered for repeated impact absorption without losing structural integrity across a full season.
The Zero RF Vest isn't a snow-only piece. The ultra-soft, lightweight build breathes well enough for mountain biking, trail riding, and snowsports — any sport where a slam onto your back is a real possibility.
Full torso coverage in a single lightweight layer — flexible rib padding that bends with every turn and landing, and soft chest cushioning for the falls you don't plan. Every angle, every impact, one vest.

Frequently asked questions
What is the difference between the Zero RF Vest and the X V7 Impact Top?
They're built for different levels of protection and different types of riders. The Zero RF Vest is the everyday option — EN1621-2 certified RZ Labs back guard, recycled D3O RF underlay at the spine, and soft air foam at the chest and ribs. It's slim, lightweight, and designed to be worn under any jacket without thinking about it. The back and spine are its priority. The chest and rib padding is comfort cushioning, not CE-certified impact armor. The X V7 Impact Top is the full protection system — six CE EN1621-1 certified D3O® pads covering shoulders, elbows, back, ribs, and abdomen, with ACF compression fit and X-Connect compatibility. If you're riding park, hitting big features, or want certified protection at every upper body zone, the X V7 is the right tool. If you want reliable certified spine coverage in the slimmest, most wearable package, the Zero RF Vest is built for that.
Can I wear the Zero RF Vest for mountain biking and other sports, or is it snow only?
The Zero RF Vest is built for all-season, multi-sport use. The lightweight, moisture-wicking construction handles body temperature well enough for mountain biking, trail riding, and shoulder-season sessions where a full impact top runs too hot. The RZ Labs back guard and D3O RF foam respond identically to impacts regardless of season or surface — a backward slam on a mountain bike trail puts the same demands on your spine as one on a ski slope. Riders use the Zero RF Vest across snowboarding, skiing, MTB, and any discipline where spine protection matters and bulk doesn't work.
Will the Zero PLUS RF Vest fit under a ski or snowboard jacket?
Yes — fitting cleanly under a jacket is the entire design brief. The Zero PLUS RF Vest uses an ultra-soft, lightweight construction that sits close to the body without creating visible bulk at the back, shoulders, or chest under outerwear. The vest profile is significantly slimmer than a full impact top, making it the preferred choice for riders who want spine protection without any noticeable change to how their jacket fits or moves. Most riders wear it directly over a base layer under their shell or insulated jacket. Size according to the Demon chart — a correct fit should feel snug but not compressive, with no bunching at the shoulders or waist.
