Q36.5 Gregarius Grid Skin Bib Shorts Info

The Q36.5 Gregarius Grid Skin Bib Shorts build crash protection directly into the fabric rather than adding it as a separate layer. Q36.5's proprietary GRDXKN^® technology uses 4D printing to embed a protective grid structure into the material itself, distributing impact force and absorbing energy on contact with the road. Q36.5 states the structure has been tested in crash simulations up to 100 km/h, delaying the point at which the fabric gives way and reducing the risk of road rash in a slide-out. The pattern is cut to minimize seams throughout, and the fabric itself is made from 100% recycled UF Knit44 ECO yarns.

In the saddle area, Q36.5's C-Interface shaping removes the center seam entirely, using a high-tech Dyneema material at the saddle-bib interface for durability without sacrificing breathability or freedom of movement. A lumbar support panel, built from a proprietary high-density woven fabric, adds graduated compression through the lower back and glutes — Q36.5 credits that added stability with helping riders maintain power output later in a ride. The chamois is Q36.5's Super Molded Anatomic pad, paired with the brand's Democratic Fit for a supportive, all-day fit on long rides.

The Gregarius Grid Skin Bib Shorts are available in Black, sized XS through XXL. They're built for riders who want genuine crash protection in a bib short that doesn't compromise on the compression, support, and seamless comfort expected from a performance-focused pair of bibs.

The RA Perspective

The Grid Skin is Q36.5's attempt to solve a problem most bib shorts don't even try to address: what happens to your skin in a crash. The GRDXKN printed structure is a genuinely different approach from padding or reinforcement panels — it's built into the weave itself, so it doesn't add bulk or change how the short fits day to day.

The 100 km/h crash simulation figure is Q36.5's own testing claim, not something we've independently verified, so take it as the brand's framing of the technology's design intent rather than a guaranteed outcome in any specific fall. What we can speak to is that the short doesn't feel any different from a standard high-end bib in terms of comfort or compression — the protection is invisible until you need it.

The C-Interface saddle panel is the detail that stands out in everyday riding. Removing the center seam entirely makes a real difference over a long ride, and the Dyneema material at the saddle interface has held up well to repeated use without breaking down the way some contact panels do.

We'd point these at riders doing long solo rides, descents, or group rides in traffic — anywhere the odds of a fall are higher than average — who want a bib that treats crash protection as a real design consideration rather than an afterthought.
