CamelBak MULE Hydration Pack 3L Designed for big mountain days, the CamelBak MULE Hydration Pack combines a three-litre reservoir with nine litres of cargo capacity and the ability to carry pads and a helmet on the grind back to the top for the next run down. Five exterior pockets provide plenty of space to stash spare layers and nutrition, with a secure phone pocket for valuables and integrated tool organisation so that essentials are easily accessible. The new CRUX reservoir now delivers hydration even faster and features a lock-off switch to prevent leaks whilst the Magnetic Tube Trap holds the hose in just the right place for easy use. Comfort on warm days and sweaty climbs is helped by the Air Director back panel which channels air between the pack and the rider, and the shoulder straps are also well ventilated. Both the sternum strap and waist belt hold the bag firmly in place whether fully loaded or empty, making sure it doesn’t swing around or ride up.
