I have an osprey kestral 38L I bought about 10 years ago, I used to be a Canadian Ranger and the pack they issue you is garbage. It's still going strong, it distributes the weight well and it has never left me wanting for space.
I did take a look at the newer ones, it seems like they removed some features, probably to keep the price point down, but it was things like a side zipper for the main compartment, shit that no one uses and is probably a structural weak point anyways.
It's the only backpack I used, it could be trash for all I know, but it's a hell of a lot better than Canadian forces issued garbage.
