Reviewed by Lee-Anne Fox - 23rd May, 2021 The backpack itself is... The backpack itself is great but be warned, from Go Outdoors you will not be able to get the WS advertised, it says WS but then says one size, and the size which will arrive is medium. They will tell you their system shows that they have smalls in stock, but on the shelf and for despatch it is only mediums. They tried to tell me that WS was an abbreviation for Women's, not women's small - which would be an unusual choice in a backpack that comes in WS and WM but there you go! But if you need the medium, the price is great and Osprey don't offer this pack any more with the anti gravity frame, it's Air scape now. Go outdoors did refund me both the mediums though, even though the first was quite an old order because of the lockdown, so I can't complain.
