I purchased this pack for winter snowshoeing and shorter backpacking trips. I find I have plenty of room and the fit is very comfortable as with all Osprey packs for my body size. I like the arrangement of the bladder fitting next to the back and easy to access without having to go into the pack itself. The side hip pockets are great for keeping snacks, lip balm, my monocular and a few other items. It is a little too small to carry most smart phones. The one problem I had at the beginning was the sternum strap kept coming off on one side. It was fairly easy to put back on but a nuisance when hiking. I see that I had it too low on the catch side on the left as this is the pinch point to attach it. So now I am mindful not to have the strap too low and it is working okay and I am getting the correct fit still.
Originally, I bought an Ariel 65, but realized that pack is overkill for someone that is only 5’3 and 100lbs. I’m not going to carry that much weight at any given time. Then I bought an Aura AG 50, which is smaller capacity, but the sizing was strange and the hip belts felt stiff. The Tempest 40 seems carry almost the same amount of items as those other bag and can handle my somewhat bulkier sleeping bag due to the opening in bottom being much larger than the pre-mentioned bags. The Tempest straps aren’t as heavily pads as the others, but it’s a very comfortable bag. Just for reference, I bought the M/L due to having a 17” inch torso and even though I’m very thin, the hip belts adjusted perfectly to my small waist. The other two bags limiting in this aspect. The Aura fit great to my torso, but had a huge hip belt that I couldn’t use. So if you like comfortable, reasonable sized, packs that accommodate longer torsos (especially if you are thin with a longer torso), this might be the perfect bag for you. I love it and plan on taking it on an extended backpacking trip in California later this year. Also, I’m excited to see if this bag might pass as a carry-on since it’s only 40L.
I love my osprey tempest. It’s easy to adjust for a great fit. Comfortable so far on hikes 6-7 miles long. I’m working up to harder and longer hikes and I’m positive this will still be a great pack. Carries everything I need.
Osprey packs carry better than any brand I've tried in 50+ years of hiking. This one is perfect size & design for cold weather day hikes that call for larger puffies.
I purchased this bag recently as I wanted something smaller than my 55L pack for quick overnighters and up to 3 day trips. This pack fit perfect and I really do love all of the features. I took it on 2 back to back trips, and it fit everything perfectly with space. However, the purple dye bled EVERYWHERE and ruined multiple shirts. The whole back of the pack bled a reddish purple dye as soon as it was the slightest bit wet. I thought maybe I missed a garment dye warning somewhere on one of the labels but after checking there and the online description I did not see anything. Super disappointing because the pack really does function well and was exactly what I was looking for.
Strike One: I was unable to get a 2 liter hard spine Osprey bladder into the external hydration pocket when the pack had gear in it (not stuffed). Strike Two: Couldn’t get water bottles into the forward pockets because they were too hard to reach and the compression straps block access. Strike Three: Hipbelt pockets too small for a phone. Strike Four: Suspension system felt like a kid’s backpack. Not sure how this pack got such high ratings! I still love my Aura AG 65 for big trips!
This pack was overall very comfortable. The adjustments that can be made are nice. The back panel feels really comfortable while moving around and doesn't rub. When adjusted to your needs the weight stays pretty evenly distributed throughout the back. Doesn't put too much pressure on the waist area. The harness mesh was really comfortable on the curves of the body. My only downside to it was that it was not built for a girl with a football player stance in the shoulders, and it felt tight. Great bag, and I can see why this line of packs is popular.
This is a perfect smaller pack for shorter or lightweight treks. I’ve used it for shorter trips (2-4 days) in the Sierras and it fit all my solo backpacking gear, including my ridiculously large and heavy bear canister, perfectly and comfortably. I also used it for 10 days on the Haute Route in the Alps and it fit all my gear plus a couple days of food with room to spare. I’ve loaded it with 25-40 lbs of food/water/gear and it always sits comfortably on my body. I’ve owned quite a few backpacking packs and this one is my #1 fave at the moment. Because it’s a lighter weight pack, the back frame and hip belt are more minimal and it doesn’t have all the bells and whistles of a heavier-duty pack. But I don’t need all that and I appreciate the saved weight. The only negative, as other reviews have mentioned, is that the water bladder is difficult to fit in the external space, especially when the pack is loaded. I was able to use my 2.5 L Osprey bladder, filled to the brim, by inserting it before I loaded my pack… this would not be very convenient if you have to refill the bladder mid-hike, but I rarely need more than 2.5L of water during my daytime activities. Overall, if you are looking for something that is lightweight (not ultralight) and versatile, this may be a good pack for you! I think packs are like shoes, and our preferences vary as much as our body shapes and sizes. I always recommend that you go to an REI store and try on the pack loaded with 20-30 pounds of weight… adjust the straps and walk around a bit to get a feel for what fits you right! A good fitting pack can make or break a trip! Good luck!
I needed a light-weight backpack to carry my work gear (lunch, snacks, work clothing, packed down puffer insulated jacket, toque, and often a lap top computer) back & forth. My old pack was quite dated and was starting to hurt by back and neck (carrying 10-15 pounds of gear). The Rep at my local store was extremely helpful and encouraged me to size up to the 40L, which I'm so glad I did. I rarely always need all this space, but it's super handy to have if needed and for most times I can just cinch in the straps to easily adjust for a smaller load. I absolutely LOVE this pack!!! It's light-weight, and the women's specific design ensures a great fit instead of trying to get into a man's oversized version. I also bought the waterproof cover for wet, rainy days. Only con is that in next version I would include a few more zippered pockets on the outside (and inside).
I used this pack for years working for the Park Service. Several other rangers bought them because they liked mine. Simple and minimal.
