Great multi-purpose pack

  • Familiarity: I've used it several times

We are getting back into BPing after quite a few years and this time going light weight. The one thing about packs, it is essential to get one to take the load properly on your body with comfort. Any weight you save with a super light pack that will not comfortably carry the load will haunt you each and every mile. We tried everything and chose (2) of the 40-10's because of their superior suspension and extremely comfortable hip belts and shoulder pads. The pack conforms to the back very nicely which keeps the load inward toward you center of gravity, not hanging off pulling at your shoulders like many packs such as the trampoline style suspensions. The pack has minimal features which keeps overall weight down but still retains a few nice luxuries like a nice USABLE sized hip pocket, double pocket top cover and nice sized side mesh bottle pockets. The materials used are quality without going overboard in weight. No pack cover is no problem. We use a pack liner instead to keep gear dry as a pack cover is simply not as reliable. We do many fly away vacations where the pack will do double duty as a carry on and daypack in backcountry areas. The 40-10 is perfect for these more serious day hiking outings in the mountains and high plains area where more gear is needed for unpredictable severe weather conditions. At first the only thing I didn't like about the pack was the lack of a left side hip pocket. That's until I found I could tuck my map inside the material that wraps around the hip belt there or attach my binoculars when hiking and birding. Now I don't miss it a bit. Every pack is a compromise but in this one we have found little to complain about. Try one. I don't think you will regret it.

Travel backpack

  • Gender: Male
  • Familiarity: I've used it several times

I had a Deuter ACT 50+10 for years and traveled with it all over BUT I carried a daypack jammed into the 50+10 and threw the whole assembly into a duffel at the airport and checked the pack.
I ditched the daypack and duffel to carry just one pack with me; the ACT 40+10. I use a foam insert for my camera gear (a Nikon DSLR and a couple lenses). This way I carry it all on the airplane with me. The 40+10 fits into overhead compartments when you do not extend the pack.
I strip out the camera gear insert when boarding and the pack looks like a daypack and I am carrying a handled foam box.
The 40+10 is that perfect crossover size, fit and comfortable - small enough to carry as a daypack, small enough to fit in overhead compartments, comfortable enough to carry in the tropics loaded with 30lbs (I rarely carry more than 18 pounds). I carry it on trains, buses, tuk-tuks and of course, my back.
The only thing I question is the long term durability of the stretch fabric. I try not to use the back pocket because of that. Oh, and that I had to locate a suitable silicon nylon rain cover. They should include a cover for a pack that works so well in the tropics.
Lastly, I am 50, 6' and 210 and this pack ( and the other Deuters I own) is a truly comfortable pack for all sizes. They figured out the suspension system that works for nearly any back length or body. My wife, who was using my 50+10 has now picked up one of these AND my son wanted his own new 50+10 (he will check his)! I have a lot of backpacks in my usage collection, from daypacks to my Bora 80 and Lowe SAR pack - and this pack wins, hands down for everything from a daytrip to overnight to, well, a three week trek in SE Asia. Expect to see it on the Camino Santiago in the near future!

Comfortable, but questionable quality

I got this pack and used if for about two weeks and ultimately returned it. It is really easy to adjust the shoulder straps to match your torso length and after you get over the weirdness of how the shoulders feel it works really well. The waist belt is super beefy for the size of the pack and makes the load feel really secure. I ended up returning it because it was not sturdy enough for my taste. I noticed that the straps to hold down the lid were stretching at the stitching where the webbing meets the lid (it seems to be some sort of synthetic leather). Additionally I was tightening one of the side straps and the clasp snapped. The only way to fix it would be to cut it off and sew on a new one.
I ended up getting the Osprey Exos 46 which is lighter and seems more durable even with smaller straps.

Excellent overnight or winter pack

Light weight, comfortable with convenient pockets, solid construction and great cooling. The "one-sizing" of this pack would be my only complaint, at 6'1" I find that I'm at the extreme end of fitting this pack. The addition of a rain cover would have been a nice touch too, as I had to buy one separately.
