Rated 5 out of 5 by from function meet form When I needed a bigger pack for multi day hiking, my top two concerns were weight and my collarbone. This pack is stiffer than the other packs I tried on, with a lot less cushioning. I have lower back problems and I found the tight stiff fit to be more beneficial for my back, almost like a back brace. The packs up lift strap system, when used correctly, also greatly helped my lower back by lifting all the weight higher. In addition, since my pack fit tighter against my back, there was less shifting of the pack overall, which helped prevent any chaffing on my collarbone. Also, I really liked the bungee clips that hold your poles/ice axe. They have a plastic hook that hopefully holds up. Plus, you can hide them when not in use. Such a pretty backpack!! My biggest problem is overpacking. Not the packs fault. :/

Rated 5 out of 5 by from Comfortable and Convenient I have a petite frame (15" spine, 24" waist) and this pack fits like a dream. With Osprey packs I've always found them to pinch at the shoulders and the waist straps be too stiff to manage. This pack's straps are positioned far enough apart to be comfortable and the waist straps bend at just the right spot to not be annoying trying to get into. Plus, that zipper across the bottom is the best thing I've found in a long time.

Rated 5 out of 5 by from First Backpack Performed Well I wanted to start taking some weekend long backpacking trips and decided it was time to invest in my own pack. I spent about 2 hours at my local REI having different ones stuffed and adjusted to me. Ultimately it came down to the Osprey Aura and this pack. Hoping to save a little I chose this pack because of price. This weekend I took it on a trip and it performed amazingly. I definitely overpacked, to the point I had to squeeze things in tight to zip it up, but it felt light as a feather. Over the 30 miles it barely felt like I was carrying anything. There are plenty of adjustments to make it form right to your back. One thing I liked better than the Osprey was the hip belt pockets. The ones on this pack are made of stretchy breathable material which allowed me to put more items I wanted within hands reach. Overall I am extremely happy with my purchase. Bottom line though, go to the store and find ones that fit you because no two bodies are the same.

Rated 5 out of 5 by from Great pack for long distance hikes I bought this pack halfway through my thru-hike of the AT and loved it. I did not like my Osprey and wanted something smaller and more convenient. It fit all of my gear perfectly, the waist belt pockets were great for snacks and holding my phone, and I loved being able to access my water in the side pockets with little effort. The pack also lets your back breathe more than a lot of other packs so I ended up being more comfortable in the summer heat than my companions. The pack can put a lot of pressure on your lower back when I didn't pack it correctly but the compression straps allow you to adjust the weight a little higher. The only big issue I had was things would fall out of the side pockets pretty easily so I had to check the ground whenever I set it down or fell. After 1100 miles it does not show too much wear and tear and I will definitely keep using it.

Rated 5 out of 5 by from So comfortable! I just wore this pack hiking the Wonderland Trail ( 93 miles around Mt Rainier). It is so comfortable, the hip belt fits well and really does its job of taking weight off the shoulders. (I recommend watching the REI video on how to put on a pack - it really makes for a good fit). I also liked the pocket arrangement and lovely color

Rated 5 out of 5 by from Very nice pack!! I went for a two day 36 mile hike and this pack was amazing!! All the very accessible compartments are quick and easy to get to your things. My pack weighed in at about 30 lbs and it was still comfortable and easy to pack!! I highly recommend this pack to any woman. Not to mention how pretty it is;)

Rated 4 out of 5 by from Light and I bought the medium size of this pack (the largest available) to lighten my "base weight" on three-season multi-day trips. It weighs a pound less than my Osprey Aether 85. On a 7-day backpacking trip in Wrangell-St. Elias National Park the first week in August, the pack held my personal gear, food (in an Ursack), and some group gear - the two-person tent and a pot. I am 5' 4" tall and weigh around 130. For me, carrying the tent under the top flap worked best in terms of how the weight rode. The small pockets on the hip-belt were useful for snacks, sunscreen etc.. I like being able to access the main compartment from the front as well as the top. Two negatives - First, the side pockets on the pack are cut at an angle and are therefore shallower.. I found that when using a water bottle, or the Sawyer squeeze-water filtration system, the bottle or container would fall out when I bent forward - for example to climb over obstacles or to tie my boot. That said, you can buy a small fake carabiner to clip the water bottle in, and the Sawyer filter is tall enough to be shoved under the cinch strap. If you are using a camel-back for water, there is an internal pocket for the pouch, but of course this reduces the amount of packing space you have. Second irritation - when the pack and the top pocket are fully loaded, the strap that flips over the top of the pack to click into the top of the front pouch is several inches too short. Of course this can be fixed by tying in some extra webbing to lengthen the strap - I have not checked to see if REI sells the right size webbing. Overall, I am pleased with this pack and plan on using it for many years.

Rated 4 out of 5 by from My second backpack I love the bag. The color is great and design is good. The only things I don't like about the bag is that the compartments/pockets on the waist belt are too far back on the side. It's very difficult to get in and out of those pockets. The other thing I was a little confused about are the straps on the bottom where you would put your sleeping mat or sleeping bag, they just aren't very long so depending on how big your item is, it may or may not fit.

Asked by: tarastogi
The dimensions of the Flash 60 Pack are approximately 27 X 18 X 14.5 inches. Typically carry-on size bags and packs will not exceed 40 liter sizes, so this would not be a suitable carry-on pack.
