The Nukeproof Blackline Short Sleeve Jersey is fully updated so it's better than ever. The jersey blends two Italian made performance fabrics to ensure the jersey performs where needed - when you're ripping along mountain bike trails.
The front body and sleeves of the Blackline Short Sleeve Jersey are constructed from a lightweight fabric (115gsm), highly breathable yarn that is super soft against the skin. Its mono stretch piquet fabric allows unrestricted movement and the increase wicking moisture alongside minimised drying manages your riders core temperature. It’s also abrasive resistant to ensure the Blackline Jersey stays looking fresh.
The super lightweight (110 GSM) warp-knit back panel regulates body temperature by maximising the airflow out of the body and is both quick wicking and fast drying. The jersey is a trail fit, so designed to be worn loose against the body. Lastly, with its natural UV protection and an anti-bacterial finish, this is a jersey ideally suited to hitting the summer trails.

Based on Innerleithen High Street in the Tweed Valley our shop lies in the shadows of the infamous Golfie. An Enduro World Series venue and legendary in the UK mountain bike scene as one of the most prolific and exciting mountains to ride in the UK.

Our business began as Dirt School in 2006, a mountain bike coaching company set up to deliver the best learning and support a mountain biker could ever want. From World championship wins to the award winning BASE college course, we've experienced and forged it all. Our evolution led to the formation of Tweed Valley Guides and now Tweed Valley Bikes too, allowing us to help you buy the right equipment, and be able to ride with you on the best trails and help you learn how to get the most out of it. Our shop has genuinely grown from the trail.
