Another vote for the Aarn bodypacks.
It’s the only lightweight pack system that works from a different principle – distributing the weight between the front and the back of your body so you can walk with a natural center of gravity. It’s unlike any other type of pack.
It’s been proven in the ergonomics lab to enable a more natural posture, and in the field many people with bad backs have found it transformational.
Personally, I find I can walk for weeks without a single ache or pain in my shoulders, back and hips – something I have never experienced with other packs. I also find it reduces fatigue and improves balance.
I do have some reservations about the detail of the designs – I think they could be made lighter and simpler. But if you’re walking with back-pain you really should give the bodypacks a try and see if they help.
My only advice would be to give them a fair try – at first they feel a bit unfamiliar and it can take you a little time to get the fit dialled in.
