Demon United FlexForce Pro Spine Guard — PE Flex Panels + Hard Shell + Air Shield. Spine to Kidneys. All Day.

Most back protectors protect your spine. The FlexForce Pro protects your spine, lower back, and kidneys. PE Flex Control panels move with every flex and twist of your torso. Performance foam and a hard outer shell layer absorb and deflect impact. The Air Shield kidney protection zone extends coverage below where most protectors stop. Backpack-style swivel straps, fully adjustable length and waistband, youth through adult sizing. Full-coverage spine protection built for serious riders who want every zone covered — not just the obvious ones.

The spine is the obvious zone. Every back protector covers the spine — the question is what they do about everything below it. The lower back and kidneys are impact zones that most protectors leave exposed, and they're zones that riders hit hard on backward slams, compression landings, and the kind of low-back impacts that come from catching an edge on ice. The FlexForce Pro closes that gap.

The protection stack starts with PE Flex Control spine panels — segmented polyethylene panels that run the length of the spine and articulate individually as your back flexes. Unlike a single rigid shell that fights torso movement, PE Flex panels move with you through every crouch, jump, and landing while maintaining structural integrity on impact. They don't bend when they should be rigid; they flex when you need them to and lock when the hit comes.

Over the PE Flex panels, a combination of performance foam and a hard outer shell creates the two-stage impact sequence: the foam absorbs and cushions the initial energy, the hard shell deflects and distributes the remaining force across a wider area before it reaches the spine. Neither layer alone handles the full impact spectrum as well as both together — this is the multi-layer construction that separates a serious spine protector from a foam sleeve.

Below the spine zone, the Air Shield kidney protection extends coverage to the lower back and kidneys — the zone most back protectors end. The Air Shield is specifically shaped for the kidney area, providing structured protection at the flanks while maintaining the flexibility needed for full range of torso movement. If you've ever taken a lower-back slam and wished your protector was 3 inches longer, the FlexForce Pro is built for that exact moment.

The backpack-style swivel strap system distributes the weight of the protector across the shoulders rather than relying solely on a waistband or single strap — making it significantly more comfortable for extended wear than protectors that put all the tension at one anchor point. Combined with the adjustable length and waistband, the FlexForce Pro fits every torso from youth through adult with consistent pad positioning at the spine and kidney zones regardless of size.

Low-profile under any jacket, full range of motion in every direction, sized from youth through adult. The FlexForce Pro is the spine guard for riders who want complete lower back and spine coverage in one piece of gear — and who plan to wear it every day rather than leaving it in the bag when the terrain gets serious.
