The Pulse 12 backpack from the BBR collection stands out with its original design which reminds the colors of France and its new RIPSTOP 30D material which is even lighter and more water resistant. It has been designed by the feedback of our best athletes for the most demanding traileurs and ultra-trailers. This backpack is worn like a vest next to the skin.

With its large storage capacity, it allows you to keep the essentials close at hand and to carry everything you need for short or long distance races.

It consists of: a large zippered pocket for smartphones, elastic pockets that can accommodate 2 flasks of 500ml and nutrition, a whistle, chest and belly adjustments for better distribution of the load on the back, side velcro to adjust the bag according to the capacity and your size, and the back : quick access to a 4way stretch pocket to accommodate poles or a jacket without having to remove the bag from the back, the main compartmentalized pocket to separate the water pocket and organize the storage of your equipment.

For more security, 4 reflective loops have been placed on the front and back of the bag, allowing you to attach a Mesh net to increase the volume of the bag if needed. The Pulse 12 backpack is water resistant, allowing you to use it in any weather.

It’s the perfect balance of lightness and stability, so you’ll quickly forget about it while running. Its highly breathable 3D Coolmax® fabric boosts thermoregulation.
