Peak Aspiration

  • Peak Aspiration is our most popular Stronglite. Our Stronglites are designed to take your gear into the world's remotest places comfortably and reliably. They are tough, dynamic, multi-functional.  Fully featured, they allow you to carry a wide variety of adventure tools for diverse conditions and multiple activities. Add Balance Pockets for natural balance, pain relief and load-carrying efficiency. Choose the specific Balance Pockets, Bags or Racks that match your activity and volume requirements. The Stronglites have proven themselves in the roughest backcountry and on the world's highest mountains.


    Our frame architecture combines a 7005 alloy rod hourglass-shaped frame with 1 horizontal hollow 6001 T6 aluminium stay. This maintains the slim profile when the pack is stuffed full yet the stretch back-panels can auto-mould to your back shape when the hipbelt is done up. Backpanel ventilation is outstanding with a suspended mesh backpanel.

“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’”.
Mark Watson, Editor, NZ Climber magazine

"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 Balance Pack 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".
