COMPRESSPORT Ultrun S Pack EVO15 L Size 15 Liters Trail Running Backpack Trail Running I made an impulse purchase after trying it on and liking the fit, but I'm selling it because the Salomon I'm currently using still seems usable. Comes with two soft flasks. Thank you. ~From the website~ A large-capacity 12+3L trail running backpack. With plenty of pockets to securely hold your belongings and an ergonomic fit, it's suitable for long mountain trips. The two front mesh pockets for soft flasks are easily accessible and have dedicated loops to prevent the flasks from bouncing while running. Near the shoulder blades, there are small pockets convenient for storing keys, energy gels, and wrappers from consumed food, and at the bottom, there's a large Velcro-closure compartment for gloves, headbands, food, etc., which can be easily accessed by pulling the tab. The diagonal zippered pocket on the left side of the abdomen is also easily accessible, making it convenient for storing a mobile phone when you quickly want to check your route or contact your support crew. A zippered pocket is also located on the back to store ID, money, emergency blankets, and other essentials that are not usually taken out. Furthermore, the back has a pocket to securely hold a hydration bladder and a dedicated loop for the tube. A large elastic pocket is also provided at the bottom of the back for storing necessary clothing and equipment. Jackets and rain covers can be secured to the elastic straps on the back surface, and poles can be secured to the silicone toggles on the outside, so they don't get in the way. Like other COMPRESSPORT products, the vest body is highly breathable and ergonomically designed, with soft seams for a very comfortable fit. Foam inserts are placed on the front to prevent chafing on the chest that can occur during long periods of wear. In technical sections, pull the side straps tightly to increase stability, and in climbing sections, open the front zipper to further increase breathability for comfort.
