Waging war against weight, sweat, and the one-act pack.
Deuter designed its ACT Zero 50+15 Backpack for fast and light thru-hikes, weekend backpacking trips, and overnight summit attempts. The versatile design of the ACT Zero won awards when it was first introduced, and little has changed as the years have rolled by. Deuter kept the ACT's top-loading design with a height-adjustable lid and spin drift collar, which doubles as a roll-top closure if you decide to shed some weight by popping the lid off. The popular AirContact suspension system remains intact, with breathable mesh-covered hollow-core foam padding that wicks moisture to keep your back cool and comfortable when you're on the trail. Deuter ensured the Vari Quick harness system can be used to adjust the back panel quickly and easily to accommodate different torso lengths, making the pack a great options for folks who run between sizes.
It's not the most gizmod and gadgeted pack out, but the ACT Zero's basic design saves weight, boost usability, and still features two side pockets, an internal hydration sleeve, and a front sleeve pocket for extra layers. The front of the pack is fitted with ice tool loops, trekking pole straps, and side compression straps to keep everything snug and secure when you're on the move, whether your load is giant or ultra-efficient.

ergonomics vs weight
- Familiarity: I've used it several times
I had to replace my Granite Gear Crown VC 60. This pack is more than a pound heavier but it feels much lighter as it very efficiently transfers the weight to the hips. So I had no pain on my back and shoulder, a problem I had with my previous packs and made me consider to reduce my trips. I looked into many other packs but most of them add more depth to the pack and push the weight further away from the torso so less good transfer to the hips and less stability when climbing over rocks or fallen trees.
I had no issues with carrying a bear-box with the added volume and weight. With extended collar the pack becomes quite deep and extracting items less easy but if one does not need it it can be folded inwards and then basically disappears.
