Grom Race Kit - Grunge Chalk
Description
Built for full-send days and endless laps, the Grom Race Kit is made for young riders who live to shred. Lightweight, tough, and dripping with style, this matching kit brings serious trail energy with a bold White and Black grunge design that hits just as hard as they do.
The Velocity Jersey keeps things cool when the riding heats up. High-performance hex micromesh and a lightweight open-mesh back panel mean maximum airflow, fast drying, and sweat-busting comfort, so they stay fresh from first drop to last lap. It’s made for kids who don’t blend in and don’t want to.
Matched with the jersey, the Shred Trousers are built for all-day riding and full-commitment sends. The lightweight design moves freely on the bike, while the adjustable ratchet waistband grows with them. Big zip pockets lock down essentials, and kneepad-friendly ankle cuffs keep everything dialled when it’s time to push harder.
From first rides to full-on trail ripping, the Grom Race Kit delivers the comfort, durability, and unmistakable style young shredders need to ride faster, send bigger, and shred longer.

Trouser Water Repellency
These trousers are not waterproof but do offer a good level of water spray and dirt repellency due to the nature of the material used. You can increase the lifespan and further enhance the water repellency by using one of our Grangers repell plus spray or repell wash-in care products.
