Symmetrical, stylish and practical. Carry the TRT 10 sling bag over your left shoulder or your right shoulder - it's just as comfortable either way. Access to the compartments is easy from both sides and, thanks to its innovative 3 point strap attachment system, the bag doesn't swing around when you're riding your bike or running to catch the train.TRT stands for 'tough, rough, technical' - the backpack series for the tech-savvy user who wants a product that's built to last. The bag is equipped with multiple gear loops on the front.The TRT 10's modular gear loop system is a particularly clever feature. The loops are partially concealed behind the slatted panels on the front of the bag and can be pulled out when needed. Each loop also functions as a high-vis reflector. So even when they're tucked away, you'll still be visible in the evening traffic.There's plenty of room in the large main compartment and front compartment for your big city survival kit. Another cool feature is the detachable key tape with bottle opener.
