Impact shorts marketing loves to promise "maximum protection," so I went straight to Demon United's actual X V7 D3O A.I. Men's Impact Shorts listing — including its 53 verified reviews — to see whether the triple-pad system actually holds up to real slams.
The X V7 is Demon United's flagship lower-body protection, built around three integrated D3O® impact pads covering the tailbone, hips, and thighs. Pricing starts around ~$110 (2.936.000₫) for the base Small size without suspenders, scaling up by size, with a 4.79 out of 5 rating across 53 reviews.
Rather than protecting one zone with one material, the X V7 uses three independently-responding D3O pads. The centerpiece is an upgraded T6 tailbone protector, CE EN 1621-1 Level 1 certified — Demon's highest-rated tailbone pad. D3O stays soft and flexible during normal riding, then instantly hardens on impact to spread force across a wider area, before returning to its flexible state immediately after.
Demon's new A.I. (Air Pad Integrated) Plush Padding™ system uses zone-mapped air-channel architecture that varies softness and airflow depending on whether that zone is flexing, compressing, or absorbing impact. The T.P.S. (Total Padding System V2) is an industry-first modular insert giving 2 inches of multi-directional adjustability, letting riders position coverage exactly where their body and riding style demand rather than relying on a generic sizing template.
The Cross-Belt Integration System (C.B.I.S.) uses dual overlapping tension straps to lock the waist and stabilize the entire pad array, preventing sagging or shifting mid-run without cutting off circulation. For riders who also wear a Demon top, X-Connect Technology links the shorts directly to the top, closing the gap between upper and lower body protection and adding a low lumbar pad. The shorts are also cross-generation compatible with Demon V4 through V7 systems.
Built from a ventilated Lycra/mesh blend, the shorts are lightweight, moisture-wicking, and low-profile enough to sit cleanly under snow pants or ski pants without adding bulk. Reviewers consistently describe the fit as comfortable enough to forget you're wearing armor — until the moment it's needed.

For park riders, freeriders, and mountain bikers who've already taken one bad tailbone slam too many, the X V7's triple D3O pads, adjustable T.P.S. V2 insert, and C.B.I.S. strap system — backed by a 4.79-star track record across 53 reviews — make it a legitimately serious upgrade over standard padded shorts.
