REI Flash 50 Pack - Special Buyis rated4.5out of5by8.
Rated5out of5byfromamazing packI bought this backpack after i tried the REI flash 45 and discovered I needed just a tad more room and I did not like the shovel pocket. This pack solved both problems. The shovel or shove-it pocket is solid and has another pocket built in. plus the large size is actually 53liters. I have taken this backpack on many backcountry camping trips including a 40mile, 2 night hike in the rockies. I carry about 22 pounds with food and water. The backpack never gave me any problems. Besides being dirty it doesnt show any signs of wear either. I would recommend REI Flash backpacks to anyone. the packs are solid and light and much cheaper than comparable backpacks. If you tend to carry loads over 30lbs. this backpack may not be for you. the padding is sufficent for lighter loads but could be lacking if your packweight is 30+

Rated5out of5byfromGreat packSo I wanted a new pack for overnight ski mountaineering trips. I splitboard a lot in the Pacific Northwest. Usually 1 or 2 nights, to climb and ride the big volcanoes we have here in Oregon and Washington. So I wanted a comfortable, light 50L pack as my 42L was not cutting it. I looked at the 50L offerings from pretty much every brand. Some offered more ski-specific features, but they were all over $200 and some were over $400. This pack caught my eye, but it didn't have any ski or snowboard carry features. However, I rigged my own snowboard carry with 2 48" webbing straps with buckles. Done. Now I have vertical snowboard carry and diagonal ski carry. This pack, although weighing just over 2 lbs., is by far the most comfortable pack I've used. On a recent overnight trip to Mt. Adams, I was able to carry over 25 lbs of gear plus my splitboard (over 10 lbs) very comfortably. If you're like me, and willing to skimp a bit on bringing extras, this pack could easily carry you through a week or more. So light, so comfortable, so inexpensive. Done! Great job, REI.

Rated5out of5byfromAwesome pack for the moneyBought this pack for my first backpacking trip. Decided on an REI because of their reputation for quality and warranty. Pack was comfortable the entire trip while my friends complained of packs shifting and digging in mine never did. Also several of the "great deals" on packs they found ended up with busted seams and buckles. I intend to use this pack for many trips to come. Buy a good pack like this one to start with (or buy one after the bargain one dies after one trip)

Rated5out of5byfromGreat lightweight packthis backpack pretty much rocks. i own several other multiday packs including other lightweight packs around the same weight and this one is so far the most comfortable. i also own several hydration vests, and daypacks and this pack would prolly be my number one choice for all those situations. the last flash model i tryed which was the yellowish colored one had very uncomfortable padding which was about the only thing i found wrong with it but it was a deal breaker. this updated one has very simple comfortable padding that rides perfectly on my hips in a way no other pack really does. i like the ability to remove the stay and lid for weight savings, however the stay workers too efficiently to justify taking it out, but on most my trips i would prolly do alright with a packcover serving as the lid and can usually cut that weight out. the pack is extremely light yet large and has definantly been an improvment that helps maximize my hiking experience. the material is stong and zippers seem real tough and waterproof. ive taken it on day hikes through the rain and it takes about 3 hrs for the first beads of rain to start soaking in but seems much more water resistent than other softer fabrics ive encountered. im glad they chose to go with 3 different sizes vs a adjustment system cause it cuts out that uneccesarry weight but i probably wont be able to let my friends borrow it like my adjustable pack. the different straps allow for you to really sinch that weight in close to your back when you fully utilize them. so far with about 100 miles under this packs belt i couldnt be happier and will be taking this one on the 220 mile hike i plan on doing this summer.

Rated3out of5byfromNot what I expectedNo doubt its a nice pack, but material looks to me cheap. Too thin and Im afraid it will get torn quite easily in the bush. Some of my hikes take me off the trail, so with its "delicate" construction looks its not going to last long.

Rated5out of5byfromGreat valueThis pack is an absolute steal at the outlet price. I've been using mine for a few years now and have yet to find another that balances weight, features, and capacity so well. The materials have held up great over hundreds of miles of trails, storms, mud, and branches; and the pack has stayed comfortable all the way. I have really appreciated the zippered pockets, which allow me to organize things and provide quick access. Looking at other packs online, I'm always amazed this one has so many features for the low weight.

Rated4out of5byfromExcellent pack for the moneyI love this pack. It is a really well-designed, light, and durable pack. The only nit-picky flaw I could think of is that I'd really like a separate, waterproof (in case it leaks) compartment with a drain hole for the water bladder. However, I'm not aware of any pack that has that feature either. One of the key things I like about it is that the outer pouch can be opened out enough to put my hydration pack w/minimal survival gear into it. That minimizes gear redundancy and gives me the option of hiking away from camp with my hydration pack. I looked at and tried quite a few day pack options and this is, by far, the best one I've seen. REI really did a stellar job on this design.

Rated4out of5byfromFits bear canisterI was trying to decide between the Flash 50 and the Flash 65, so ordered both. I loved their low weight and excellent price. I have not used the packs yet, but did want to pass on that the Flash 50 will hold a Bearvault 500 vertically and also will hold it horizontally, though only in the top third of the main sack. You can close the drawstring almost all the way and the top lid fits with the canister loaded horizontally in the top. Otherwise it looks extremely well made and with some very thick padding in the shoulder and hip straps, as opposed to some models of ultralight packs. Hope this helps your decision.
