Compressport Ultrun S-Pack

Designed by Sébastien Chaigneau, trail running legend, and co-directed with Compressport, the UltRun S Pack is the result of more than 10 years of experience in ultra trail running combined with Compressport’s technical expertise. From this collaboration, this 100 miles backpack was born, intuitive, the lightest in the world, 80 grams only! Designed to be extremely comfortable to conquer the highest peaks without constraint. The vest conforms to your body like a second skin, prioritising freedom of movement and breathing. Its storage spaces are organised for fast access even while running, so you can easily grab your water bottle or energy bar. It has an allocated pocket for each piece of equipment - space is optimised to the maximum. Carry up to 1.2 liters of water, food, gels, bars, vitamins, all the mandatory equipment for ultra-trail running races, sticks, personal item! The weight is perfectly distributed to maintain a good balance during the race. Attack the steepest descents faster than 20km/h without bouncing! Sold with 2x 500ml flasks - allows for carrying 2 x 500ml ergo flasks on the front for direct and easy access while at the back 1 x 600ml flask can be placed horizontally.
