The Rab Airox 24 feels right at home on hiking trails, even in warm and hot conditions: the Aerofit back panel helps keep you comfortable when you start to sweat. The Airox 24 is of a very traditional daypack size class, and suits many occasions. The long zipper opens the pack up in a big way. A detail borrowed from running packs: the easy-access pockets on the shoulder straps make it convenient to carry separately sold soft flasks and items like energy bars within easy reach. - Integrated rain cover included - Back length range: 4651 cm, measured along the back from the top of the hip bone to the most prominent cervical vertebra - Compatible with hydration bladders up to 2 liters - Small upper pocket for small items - Stretch front pocket - Stretch mesh side pockets for bottles - Shoulder straps with open pockets for soft flasks - Adjustable sternum strap - Trekking pole attachments - Zipper in the front panel for quick access to gear - Side compression straps
