The ULTRUN S PACK, designed by trail running legend Sébastien Chaigneau and manufactured in collaboration with Compressport, is the result of more than 10 years of experience in ultra trail running combined with Compressport's technical expertise: From this collaboration came the 100-mile backpack - intuitive and the lightest in the world, weighing only 80 grams! Designed for maximum comfort to conquer the highest peaks without restrictions. The Ultrun S pack is designed in the form of a waistcoat that adapts to your body like a second skin and is the main focus of your freedom of movement and breathing. The Ultrun S Pack is intuitive, the storage spaces are organized so that they are easily accessible even while running, and you can easily grab your water bottle or energy bar. Every piece of equipment has its place and the layout offers optimal room. Carry up to 1.2 litres of water, food, gels, bars, vitamins, all the mandatory equipment for ultra trail running races, sticks, personal items, etc. The weight is perfectly distributed to maintain a good balance during the race. Face the steepest slopes with speeds of more than 20 km/h without your equipment jumping!
