The Deuter ACT Zero 50+15 Backpack is an award-winning Deuter backpack that boasts a new, ultralight design for 2011.
Great for the experienced backpacker/mountaineer who needs to carry it all, without the added pack weight.
This 3950-cubic-inch, 65-liter pack can carry up to 45 pounds, yet weighs only 3 pounds 5 ounces.

Contoured shoulder straps and hip fins have 3D-AirMesh lining for added ventilation.
Hip belt stabilizer straps increase load control, and pull-forward buckle is easy to fasten even with a full pack.
Height-adjustable lid is removable, with a 15-liter resupply extension collar.

Storage includes a large, compressing front stuff-it pocket, top and bottom lid pockets, interior valuables pocket, mesh side pockets and hip belt pocket.
Ice axe and trekking pole loops.
Hydration compatible (reservoir not included)
Durable, double-layered base panel.
Alpine Emergency SOS guide printed on interior to refresh your memory on aircraft signals and emergency contacts if you're in a bind.

Nice lightweight pack

This is a classic internal frame pack: clean, uncluttered design with minimal outside pockets, a floating/removable lid, and a traditional suspension. It isn't an ultralight pack, but it is light at just over 3 pounds. It's a single compartment top loading pack, with no other zippered access, so you need to use some thought when packing. However, lack of zippers helps save some weight. The pack is highly functional in use, with enough outside storage for the things you need during the day. The weight saved by eliminating gimmicky features (stow-on-the go trekking pole storage, unneccessary zippers and outside pockets, etc.) is used to beef up the suspension. The hipbelt is very well padded, and it stays put once you tighten it (no more hitching it back up as it slides down on your hips.) The weight is easily kept on the hips and off the shoulders (unless you want to take some weight on your shoulders), and it's easy to balance the load with the load stabilizer and load lifter straps. Torso length is very easy to adjust. One of the nicest features of the pack is that you can move the point where the load lifter attaches to the shoulder strap, to really fine tune the fit; most packs use a fixed connection point, with the result that the load lifter is too far forward or too far back to work effectively. All of this results in a very balanced, comfortable carry. I find that the 50 liter basic capacity is perfect for my summer load, and the 15 liter extension collar is near-perfect to hold the volume of the warmer sleeping bag and extra clothing I carry in the winter.

I wish it came in green or gray, but the blue isn't as bright as shown in the picture; it's more of a dusty blue, so it's not too off-putting.

All in all, there are no dazzling, glitzy features that make the pack "pop" (to borrow one of my wife's favorite HGTV words); it's just a well-designed pack that performs well day after day, and does all that is asked of it. I highly recommend it.

Comfortable and light

I have been very happy with this pack, it feels lighter than it's advertised weight of 3lb 6oz. Unlike the other reviewer, my pack (ACT Zero 50+15) is one large compartment and does not have a separate compartment for sleeping bag. I prefer the single large compartment, which I line with a compactor bag and it fits fine. There is quite a bit of space in the removable lid as well.

It is very comfortable and has good adjustability, although I am 6' and have set the adjustable length to the longest setting. This is less about height, however, and more about torso length.

My complaints about the pack are minor:
- the waist belt pocket is rather small-- too small to hold my Nikon Coolpix point and shoot camera without having to squeeze it in there with both hands.
- The side pockets are deep and not easily accessed when wearing the pack. Although the pack has a hydration holder and port, I prefer to drink from a bottle and it makes it hard to grab it without taking off the pack.

Great bag

I got this for backpacking trips, shorter ones. It is great. Super comfortable and durable so far. It adjusts easily for inclines and declines. I love the separate pouch in the bottom for my bag and pad. It also has a hole in the top to feed your bladder line through and a pouch to hold the bladder in the main pouch. The only thing I would make different is ways to attach stuff on to the front of the bag and the side pouches could be a bit better. Other than that I can't complain because this bag feels great mile after mile.

Wear issue

Ive had the pack out twice in a year for a total of 5 days, travelling high and light in the Sierra Nevada. Unpacking from the second trip I noticed two "wear-throughs" on the heaviest, durable fabric on the bottom of the bag. Im pretty careful with my stuff and don't drag it around, and I pack lighter softer things in the bottom of the bag. Also, each trip the pack was 35 lbs or less. I know there was some minor butt-scooting to get down granite ledges the last trip, but holes on the bottom of the bag after two short trips is very disappointing. Also, the pack could be just a little roomier to accept a bear can easier.
