The Trail Blitz 12 is a lightweight and versatile hiking backpack developed by Black Diamond to support you on all your light outdoor day trips. Whether it's for a trail on a ridge, a light hike in parks and nature reserves in France and beyond, or for use in urban races, this hiking backpack optimizes the transport of your gear without adding unnecessary weight. Indeed, very compact, its 12 L volume offers easy and quick top access, similar to marine bags. Highly functional as well, it features both sleeves for trail poles on fast and light runs, but also 4 connection loops on the back panel, designed to attach it to higher-capacity backpacks for longer runs. Additionally, its BDFlash pocket is specially designed to hold a headlamp for night runs, and also includes an internal pocket where you can secure your keys and phone. Finally, the chest strap and shoulder straps keep the Trail Blitz 12 close to your body in all your movements to avoid hindering your rapid progress.
