“The Peak Aspiration is the most comfortable pack I have ever worn—period. Not long after I left the car the first time I used the pack I was heard to say ‘I don’t even feel as if I’m wearing a pack’. Later, I lent the pack to a friend for a trip—his feedback to me was: ‘you don’t carry that pack—you wear it’”.

"Peak Aspiration with Sport Balance pockets has opened up a whole different world of backpacking. I can actually hike all day without upper body fatigue. Walking in a natural, balanced posture while carrying weight is absolutely amazing and light years ahead of all other packs. I don’t understand why such a basic, fundamental concept as balance hasn’t caught on. I tell anyone who is interested on the trail that once you experience a balanced load you will never go back to a traditional pack. Too many people worry about weight and not at all about balance - which is fundamentally more important. The whole system has been so well thought out and executed in terms of attention to detail and quality. Just the slight cupping of the hip belt makes a huge difference in terms of all day comfort. The idea of a Bodypack is one thing, but if the design and execution aren’t there, all else is futile. In this regard, Aarn has succeeded by far. I’ve wanted to tell you this for the past two years, but have been too busy actually enjoying hiking".
