Cheers for that. Decided to stick with the Nebula for an extra £3/4 as that holds 34 litres as opposed to this holding 26l.
Osprey have a guarantee that's solid. no idea if NF has one worth checking
http://www.wiggle.co.uk/osprey-womens-palea-26-rucksack/ Use code summer17 and get it for £40.66. Or if you get your basket over £50, use code summer11. It maybe the womens version but there is no outward looks to suggest that, would be fine for most people as the only difference is slightly shorter shoulder straps and a back length which is 2cm shorter, if you were relying on a hipbelt to take the weight then it would be important, but as the waist strap is just there for stability I don't think it makes any difference. The advantage is it has the trampoline type back so less sweaty, and it also has the 'kickstand', the man's Pandion version is £80 and the new Osprey version of this, the Radial is £100+
This or the Nebula that's posted on here for 44 quid?
