Details Osprey Ariel AG 65 Trekking Rucksack Designed for long trips and heavy loads, the Ariel AG 65 trekking pack from Osprey will make light of everything you need for your favourite adventures. The back system is sized and shaped for a woman's body, and because there's really no such thing as an 'average woman' the back is adjustable and the hip belt is heat mouldable, so you can achieve the best possible fit. A sprung mesh lumbar area and stiff load bars integrated into the harness helps to transfer the load through the larger muscle groups in your legs, so you can take the weight evenly. The Ariel AG is also a miracle of organisation and accessibility - Osprey have been making these packs for a long time and they've thought of pretty much everything likely to make your life easier. There are multiple access point, including front panel access into the body of the pack, as well as a sleeping bag compartment with a wide zip entry and an internal divider. The lid also has multiple pockets and can be completely removed if you're trying to save weight - a top cover will protect the contents of your pack. Add an integrated rain cover, trekking pole attachment, compression straps and multiple attachment points  and you can organise your gear any way you like.  For the list of features that you get and for the comfort of the harness system this is one of the very lightest trekking packs available. _ SizeWeightVolumeTorso LengthHip Diameter Small 2180g 62 Litres < 47 cm 68.5 - 79 cm Medium 2280g 65 Litres 46 - 52 cm 76 - 86.5 cm Weight: 2.21kg (Women's M) Dimensions: 85 x 37 x 34 cm AG AntiGravity™ 3D suspended mesh backpanel/hipbelt Adjustable torso length Base zip entry FlapJacket™ top cover for use without lid Detachable/integrated rain cover within lid Internal hydration sleeve Internal key attachment clip J-zip front panel access Pre-Curved IsoForm™ CM mouldable hipbelt Removable sleeping pad straps Removable top lid with dual compartments Side compression straps Wide sleeping bag base compartment with divider Sternum strap with emergency whistle Stow-on-the-Go trekking pole attachment StraightJacket compression Stretch front pocket and stretch mesh side pockets Twin ice axe loops Twin zippered hipbelt pockets // Specifications Ariel AG 65 Trekking Rucksack
