    Rated 4 out of 5 by from Love this pack I love this pack! At first I had some leakage issues, and found others did as well in my research, but was loathe to return, so I carefully examined my process and discovered that I wasn't threading the cap properly, and reconciled that, and also test before zipping it in. Also, the valve that attaches to the bottom of the reservoir can be pulled out, so give it and encouraging shove, to make sure it hasn't dislodged when removing it to refill. It was simply operator error. I've had zero mold issues, unlike my experience other reservoirs. I day hike regularly for 5+ hours and never run out of water. Also, main compartment keeps things cool due to this gigantic reservoir, the only water heated up is in the hose. This is not a light weight pack but the suspension is so well designed, it matters not! I've had this for a year and would purchase it again if I had to.

    Rated 5 out of 5 by from Very happy with this pack It just arrived yesterday, and with the 20% off sale, free shipping, and my dividend, it only cost a bit over $100. That was a good start. I spent about an hour checking it out and fitting it, filling and rinsing out the bladder. I was very impressed with every aspect. I own several hydration packs, and I consider the Manta to be a superior product in most every way. I purchased this pack to do long distance, backcountry, bicycle tours - like The Great Divide. I wanted a pack that would provide loads of space for gear, plus H2O. On a MTB, leaning forward, the load needs to carry well; otherwise the lower back begins to bark. It looked good at first blush. So I filled the bladder (the rigid handle makes this extremely easy), loaded in some munchies and extra clothing, pumped up the tires on my Specialized Carve, and hit the road. Total load for this initial ride was about 15 lbs. At 10 miles out it started to rain, so I threw on the built-in rain cover, and continued on. I never felt any discomfort, everything seemed easy to access, and the fit was great (I am 5'9" and I ordered the S/M pack). The rain cover is quick and easy on/off. I really like the many outside stash pockets. One of them is large enough to stash my helmet, and I can carry 2 additional water bottles, one on each side. New for me was the magnetic attachment for the drinking valve. Attaching it back to the sternum buckle after drinking takes a bit of getting used to, but by the end of the ride it seemed much easier. My only negative comment has to do with how the drinking tube exits the hydration sleeve. My other packs use a nice little opening for this purpose, but the Osprey exits the zippered opening. That just seems funky, but does not have any impact on function. I think this pack will do everything I wanted it to do, and I can heartily recommend it to others. This is a well designed and built product.

    Rated 5 out of 5 by from Amazing pack As of yet I've been able to use this pack on several day hikes and will be doing some overnights soon. I love that it has a 3 liter bladder, which I'll admit can be slightly heavy if you are trying to shave weight but I've only come close to running out of water once on a fairly strenuous 9 mile day hike. Which really impressed me because I was in no way trying to ration my water out. It's also fit all my fall/summer layers with ample room to spare, I'm planning on using it on some overnighters with a tent and bag, I'm sure one of which will need to be strapped into the outside of the bag. Which brings me to my only real disappointment, there isn't really any strap points for larger accessories. I think they did a great job of offering points to strap on smaller gear like bike helmets and hiking poles though. Overall I find this pack to be very comfortable. I never feel chaffing or binding and the airspace that is provided along your back is great, my back hasn't ever gotten hot and sweaty due to the pack reading against it. And with Ospreys guarantee it was an easy, no worry purchase. All in all I'm extremely satisfied.

    Rated 4 out of 5 by from Almost perfect Love almost everything about this backpack, the material, spacious pockets, side access to main pouch, but the chest strap fastener with the magnetic holder broke on the first hike.

    Rated 5 out of 5 by from The only daypack you'll need Upgraded to this pack from a Camelbak and the difference is amazing. Tons of space for gear and an awesome support system, the meshed frame keeps circulation to your back and the lower waist strap has small pockets to store an energy bar or a spare battery for your camera. The reservior is solidly built and the magnetic strap is a handy feature, although it can attract small bits of rock (easily cleaned). The raincover is super handy and saved my camera and tripod after a surprise storm hit Upper Yosemite Falls. I regularly load the pack up with 30+ lbs of gear/water and can go all day without having the pack feel uncomfortable in any way. tldr - Just buy it, you won't be disappointed

    Rated 5 out of 5 by from The best day pack I've owned. Osprey's Manta 36 pack has definitely met my needs and I'm pleased I bought it. Brought pack to Pinnacles National Park for day hiking over 2 days. Walked up to High Peak and hardly noticed the backpack suspended on my back; and I was carrying 17-20 lbs of camera gear and other things...very stable feel. Also, the pack did well when moving around and through the Balcony caves...I didn't have to take it off. Great ventilation, my back was consistently dry, even at 92°F in mid/late spring. (WE 4/27). Great to have all those pockets for additional water bottles and small stuff. Positioning the pack on your back properly is key to having a good experience with any pack and the Manta feels just right when it rides low on your hip so that the lower frame bar is not resting on the small of your back and, instead, sits on the tops of you hip. I've have bad experiences with packs that "dig" into your small of the back causing aching/some numbing and discomfort. Best to get the REI backpack fit when you're looking for the right size. Also, the Manta works just as well on my back when I'm road cycling in Healdsburg/Sonoma riding and wine tasting. There's lots of room for a couple of wine bottles and your packed lunch/picnic stuff and some camera gear. But not all in that order. haha :-) Hands down, a great pack. Very pleased.

    Rated 4 out of 5 by from lightweight, comfortable I bought this for day hikes out in the Colorado 14er's and for training hikes here in MN. It's easy to load this up with 25-30 lbs of weight without losing the snug feeling on the back. I barely sweat on my back due to the breathability. The pack expands to hold quite a bit too. I prefer Nalgene bottles for drinking while hiking, so I haven't tested the hydration bladder yet. It does have a magnet to hold the mouthpiece onto your shoulder strap so you don't keep bumping it with your arm swing.

    Rated 5 out of 5 by from Excellent day pack I picked this pack up before hiking through some of the gulches and canyons in the Grand Staircase Escalante National Monument in May. This pack carries water easily, has plenty of room, is light and is capable of holding a lot of weight comfortably. The carrying system is amazing. My possibly biggest complaint is that there may be too many pockets (although I enjoyed the compartmentalization). There is enough space to carry a sweater and jacket as well as some food. The side pockets on the hip belts are useful for carrying sunscreen and chap stick. Overall, this is a fantastic pack for rigorous day hiking, especially when you need to carry a lot of water..
