Rated 5 out of 5 by from Comfortable and fits everything for a dayhike For dayhikes, this pack fits everything I need and is a pleasure to wear. My previous daypacks hung off my shoulders and made my back hurt. This pack is easy to adjust so that it balances squarely on my hips. One minus is that it's difficult to squeeze my 3-liter Platypus in the back external reservoir; it does fit, though. I've gotten the hang of widening the opening with one hand and pushing the bladder down with the other. At home in the city, I take the pack to the supermarket when I go out on foot or take the bus. It fits a lot of groceries, and I can feel like I'm training for my next wilderness adventure. Absolute right purchase for me.

Rated 4 out of 5 by from Great without hydration bladders I loved this pack in the store. I had it fitted by an REI salesperson and it felt great. The hip pockets are a perfect size, I can fit my Iphone in the pocket with room to spare (the smaller 6, not the phablet size). But the external pocket for the hydration bladder is really tight. When I squeezed the bladder inside, it deformed the back panel so it didn't fit well. Trying to fit one inside in the inner pocket is okay, but it is a little too small to fit it well. I think this is a great, very comfortable pack if you aren't looking to use the hydration bladders. One of my favorites. But if you are going to use hydration bladders, I would consider another pack.

Rated 4 out of 5 by from Perfect hip belt! Needs side compression straps. I bought this for an upcoming 2 week trekking trip in Nepal. I packed it with a sleeping bag, fleece, puffy vest, toiletries, microfiber towel, iPhone/charger, external battery, SteriPen, and DSLR camera and batteries. It came out to about 15 pounds. One of the reasons I chose this pack was the hip belt pockets. They are big enough to hold an iPhone 6 and case. The other pockets provide adequate organization as well. The only downside to the pack and the reason I will most likely return it is that it has no side compression straps. The load pulls down instead of carrying close to my back. When fully packed, the load dips below the hip belt and onto my tailbone.

Rated 3 out of 5 by from Good pack for the cost I purchased this pack for a recent hiking trip and was very pleased with its storage, features and cost. My only complaint with the pack is that the hydration pocket is extremely difficult to use. I tried every possible angle of wedging my 2L bladder into the pocket but it was impossible (even when the bladder was empty). I ended up putting my bladder into the back-most inner pocket and weaving my hose through the main zipper. Then, I connected the two zippers spanning the zipper gap with a carabiner to ensure that the backpack didn't come unzipped while hiking. Even with this flaw, the backpack was a great value and offered a lot of storage space.

Rated 4 out of 5 by from A perfect pack for multi day lodge walking I bought this pack for a 4-night 35 mile trek on the Milford Track in New Zealand, and it was wonderful for carrying my layers, a change of clothes, lunch and other necessities for hiking four days while staying in lodges. It was easy to organize, and was very comfortable on my shoulders and back. It was also perfect to use as my carry on luggage for the rest Of our NZOZ trip. The reason only 4 stars is that the included rain cover is almost useless. It rained a lot, and if we hadn't uses a waterproof bag liner, all our dry clothes would have been drenched. I would buy this pack again and would recommend it to a friend, but REI really should redesign the rain cover.

Rated 2 out of 5 by from Designed by the devil himself. Good: lots of pockets, zipper access to the bottom of the bag, and plenty of space. Bad: -It was a pain in the butt to get my 1.5 liter camelbak bladder into the space for it--and I know that size is on the smaller end so I can't imagine trying to get a bigger one in it. And this is when the pack was empty. When it was full, it was near impossible. -Maybe it's just my body but I hiked with a not-so-full pack and my less meaty parts were definitely sore for a few days following (collar bones, lower back, hips). -When the top is cinched down, it is a pain to zip and unzip in that area. I gave it a few chances. Boo, it's going back.

Rated 5 out of 5 by from Perfect for Traveling I chose this pack because it works for both traveling or hiking. I just got back from two weeks in Asia with only this pack and a purse and it worked amazing! Although it felt like a normal sized backpack, it fit quite a bit of stuff in it and was comfortable the whole time. Not to mention it fit in the overhead bins of the airplane with no problems (I also checked it a couple times with the straps cinched down and it was fine). I really liked that you can unzip the pack open flat and load it like a normal suitcase. I have yet to take it hiking but I have a feeling it is going to work just as well.

Rated 5 out of 5 by from Love this pack I bought this pack a month ago for day hikes and weekend backpacking trips. I'm 5'3" and a lot of bags overwhelm me in the 40 L size, but this one doesn't (I bought the small size). I like the color, light weight feel, multiple compartments and the material on the back of it doesn't get too hot while hiking in the summer. I've used the rain protector 3 times in the last month and it has kept the pack dry as well. It's comfortable to wear and I especially like the side pockets on the hip straps for easy access for my small camera, chapstick, and inhaler. The only issue I had was some of the tassels that attach to the zippers were missing when I bought it so it's not as easy to pull closed (easy fix, but I haven't got around to it yet). I definitely recommend this bag.

Questions & Answers

I have a question about the oregano color. On my screen it looks like what I can only describe as baby poo. Is there a chance that it's really more of an army green or a kakhi? Also: how often/at what time of year do you typically switch up the colors?

Asked by: Slidemars44
I'd say it's a mix btwn army green and khaki. It's definitely in army family of colors though. My husband wants one!

Will this fit under the seat in front of you on an airline. Jet Blue let me shove it under, but will Frontier?? I don't want to pay $70 to travel to Vegas this weekend. Meed gambling $$

Asked by: Scooterpam
This pack measures 21 x 13 x 10.5 inches, or 44.5 linear inches. Most airlines require a piece of carry-on luggage to be no bigger than 45 linear inches (L + W + H) to meet carry-on size restrictions. This can vary, so please check with your airline to confirm their luggage requirements and to check if it will fit under the seat.

Can this bag be used as a carry on for most major airlines?

Asked by: christtm
This pack measures 21 x 13 x 10.5 inches. Most airlines require carry-on items not to exceed 45 linear inches (L + W + H). The Tail 40 pack measures at 45 linear inches and should work for a carry-on. We highly recommend checking with your airline prior to your trip.

I'm looking for a lightweight backpack for day hikes with my dog. Is this too big for that purpose? I want something light, tough, and doesn't stick out too much from my back because I'd like to be as streamlined as possible. This or the 25?

Asked by: mskim
It's too big. I've taken it on a few day hikes and it's less comfortable when it has a light load. It rides too high. On a weekend backpacking trip it was great. I bought it for a week long hut to hut.
