Demon United Spine Guard X D3O® Slim Profile.

Certified D3O® spine padding slim enough to disappear under any jacket — the back piece you'll actually wear every day.

A D3O® BP3 spine insert certified to EN 1621-2 Level 1 in a low-profile neoprene shell, cold-tested to -20°C — certified spine coverage with no bulk, no heat, and no reason to skip it.

Features

D3O® BP3 spine insert (EN 1621-2 Level 1) — D3O® smart foam certified to the back-protector standard: pliable while you ride, rate-stiffens on impact to disperse energy along the spine, then resets instantly.
Cold-weather tested — Rated to -10°C (Optional Cold Test) and -20°C (Snowsports Test), so it performs the same on a January powder day as a warm spring afternoon.
Low-profile neoprene shell — Conforms to the curve of your spine and lower back, sitting clean under any jacket with no pressure points, air gaps, or movement restriction.
Adjustable shoulder straps + removable hip belt — Dial the fit to your torso and riding position; run the hip belt for a locked-in feel or remove it for a cleaner, minimal profile.
Lightweight and breathable — All-day wear on snow, dirt, and street without heat buildup.

Demon Spine Guard X D3O® — EN 1621-2 BP3. Slim Profile. Disappears Under Any Jacket.

D3O BP3 is a non-Newtonian smart foam — completely pliable through every twist, crouch, and landing during riding. On impact it rate-stiffens instantly to absorb and disperse energy at the spine. Then it resets. Certified to EN 1621-2.

The thermoformed body contours to follow your torso — that bridges air gaps and digs in at pressure points. It sits flush through every position: crouched, reaching, absorbing a hard landing.

The most effective back protector is the one you wear every day — not just on your biggest days. Slim with a neoprene shell, the Spine Guard X D3O removes the bulk excuse. Put it on. Forget it's there. Let it work when it needs to.

Frequently asked questions

The Ghost D3O covers your chest and back — the front and rear of your torso. The zone it doesn't cover by itself is the midsection: your floating ribs, obliques, and the gap between your sternum and spine on the sides. That's exactly where the Demon Ghost Rib Protector fills in. The Ghost Rib wraps around the midsection with high-density Dura Foam and a hard deflection shell, creating a full-wrap cocoon from your spine to your stomach. Together, the Ghost D3O and Ghost Rib Protector cover the entire torso — front, back, and sides — with no unprotected zone. Both are sold separately and can be worn together or independently depending on the level of protection you need on a given day.

Yes — low-profile under-jacket wearability is central to the Ghost D3O's design. The thermoformed lightweight body is contoured to follow your torso, sitting flush rather than creating the pressure points and air gaps of flat-panel protectors. Combined with the athletic construction, it adds minimal thickness under outerwear and doesn't restrict breathing, torso rotation, or arm movement in any direction. The fully adjustable shoulder and side straps let you dial the fit to your specific body shape — tighter for a locked-in feel under a close-fitting jacket, slightly looser for layering over a thick base layer. Most riders wear it directly over a moisture-wicking base layer under their shell or insulated jacket and report no noticeable change to how the jacket fits or moves.
