The Bergen is in my oppinion not suitable for hikes or long walks. Because this pack had to fit over any webbing the soldier might be carrying, the hip belt is small and flumsy. the problem is that you can not properly wear this pack on your hips and thus must carry it on your back, wich will in time.. kill it.
The thing about buying a backpack on the internet is that you can not try it on and see if it fits. yes, just like pants, shoes or hats, a backpack also has to fit. And what really anoyes the hell out of me is that if you are looking for a proper backpack on the internet, they almost every time only show the pack side of the backpack and not the strap side; the side you actually wear.
I don't know what your intentions are with a backpack, but if it's for hiking I would really recommend searching the internet for information regarding to fitting and buying backpacks and going to shops, talking to people and learning how to fit a backpack on you back, so that you can walk 30 kilometers without a sore back instead of 5 with one.
I know the frustrating thing about this is that you see a really nice backpack, good colour, good shape, excellent volume, in fact; the perfect backpack! ya think... because it is crap or just doesn't fit. I had that many times. ( even more so with sleeping bags, but thats a whole diffirent story) Anyway, I might have a few tips how to pick a good backpack and how to strap it to you body the right way. If anyone doesn´t agree or thinks I´m talking rubbish, please tell me. I joined this forum to learn
first of all you have to be able to carry the pack without the sholder straps. just on your hips. The numbers on the picture show in wich order you should strap them on. strap no. 4 is very important while picking a pack, but often forgotten. it should be higher than your shoulder when you put your pack on. Some people say it ideally should be in an 45 degrees angle from your pack. I don´t think it is actually necessary. the most important thing is that it´s well above your shoulders. 5 cm´s is ideal. this strap relieves the pressure on your shoulders, especially the back.
So. make sure every strap that attaches you to the pack is loose. First, strap on the hip belt. make sure it´s tight. ( no 1) then tighten the straps attaching your hip belt to the side of your pack ( no 2) and make sure you can carry the pack just on your hips. then tighten your shoulder straps by pulling strap no 3 down Now the pack should be fastened to you body. after that, tighten the straps above your shoulder straps (no 4) and you will see it will release pressure on the back of your shoulder straps. Finally it should have a snug fit and you can fine tune everything to your needs. I hope this helps anyone who is looking for and trying on a new backpack. Goodluck in the jungle of backpacks!
