Does anyone know the dimensions of this?...
Does anyone know the dimensions of this? I need something that is under 55x40x20cm (21x15x7inch). It also needs to be light and hardy.
It is bigger than what you are looking for. Per the Osprey web site its dimensions are:
In: 25.6 x 11.8 x 11.4
I think you are going to have a hard time finding a pack with suspension that will fit the 7 inch dimension. I did find the Manta on Osprey's web site that is close to what you are looking for:
In: 19.3 x 9.1 x 7.5
