It pains me to write this review. First off, I own what I would consider to be a good amount of Osprey gear. I absolutely love the brand and I have been through the warranty program with a backpack and it is truly the best warranty program I have ever dealt with, period. I buy all things Osprey and tell everyone! Issue#1 I ride motocross and have owned a Camelbak Thermobak 3.0L hydration pack for about 3 years. I was not having any problems with it other than it did not have any storage whatsoever. Going on motocross trail rides, I need a place to store keys and other items. I have looked at purchasing the Raptor 10 for quite sometime. The pack was recently gifted to me and I have been carrying it around work for 12 hrs. a day for about 5 weeks now. Although I hate to say it, compared to the Camelbak Thermobak, the Raptor 10 is not comfortable. When the hydration bladder is full of water, the area that rest against your back becomes convexed and rests uncomfortably on my spine which causes a very irritating pain as the day goes on. As the bladder empties, the shape becomes flatter and more tolerable, however at this point the nerve is irritated and still hurts. I have an Atmos 65 with the Anti-Gravity suspension system and can wear the pack all day long without issue. This hydration pack could use the same suspension system. I have not been riding with this pack yet, but if it is just as uncomfortable riding with it as it is walking around, I will more than likely revert back to the Camelbak Thermobak and have a pack that I don't use. Issue#2 The other issue is one that I've seen discussed on the internet and that is the strap length. I am 6' 185 lbs. and the belt straps are all the way pulled in and you are left with these weird loops at the front. It makes it harder to tighten the straps with the c-clip and still leaves you with an extreme amount of excess. Suggestions to Ospery R&D: Put Anti-Gravity system on this pack Use Boa system Include bite valve cover

Ive had the Raptor 10 going on 3 years now. This is the best item (other than a night light) that I ha ve purchased for mountain biking. I fill the water bladder at the 1.5 liter mark the night before a ride. I like the magnet hitch and the bite valve. This unit gives me peace of mind when going on long adventures in the middle of the forest or rail trails. The 10 is the perfect size for me. Very thoughtful engineering went into this back pack. I like all the compartments. It is a little pricey but it is expected to last a lifetime.

This backpack is quality, comfortable, and all the compartments in it are well thought out and useful. It is built for mountain biking, and it feels like it was designed by a mountain biker: the glasses pouch, the tool pouch, the minimalist compartments, the stretchy pocket in the back for gloves, the helmet holder... I had a problem with my bite valve almost immediately (it tore), and that's a problem. I wrote to osprey about it, and they responded saying they were sorry about that and it shouldn't have happened --they actually stood by their product-- and sent me multiple replacements immediately.

This bag is a constant companion. Walking in big cities, 20+ mile bike rides, long car rides, extended day hikes in the bush, or a full round of disc golf with 3 discs, my Raptor 10 fits the bill. Let me say why: First and foremost, it is a comfortable pack i can put on and forget about with no body complaints by sundown. Like most Osprey packs the Raptor spends its time, whether empty or overloaded, on your hips and wings, not simply your shoulders. It feels like it working with my body intead of hanging off of it. The mesh/foam back and straps are supple and supportive and the bag is very adjustable as well. Secondly(but seriously great), is the water reservoir. Ingenious design! From its ridgidity, to its ergonomic back cradling shape, to its freakishly simple and easy accessibility when refilling it, Osprey's design here should be the industry standard. If you have ever had a hydration pack you know how finicky the reservoir can be with regards to removing and inserting, as well as where the valve lay on your chest accessible but still needing to be out of the way. Osprey solved all the common problems with a simple and obvious solution. The zipper access to the reservoir begins on the right shoulder strap just above your sternum strap. It unzips up and around the lid of the pack easily and fluidly to expose the reservoir. It seriously takes me two seconds to remove and empty reservoir and four seconds to insert a full one! Yes. I said that. Then you add a magnetic attachment for the valve on the sternum strap, a valve that locks closed to prevent leakage, a helmet carrier, a zippered compartment in the outside bottom of the pack accessible when full that hides an included tool roll for flats repair, AAAND a mesh stetchy pocket on the outside to stuff a rainshell or some wet shorts? This is the most thought out hydration backpack ever made. My only con is that it cant sit upright on its own and wants to topple forward without help. Add the kickstand feature!

Got this pack a year ago, and use it for mountain biking. It fits all my tools and tubes, as well as some food in it. It has plenty of water to get you though those long hot rides. I was riding the other day and the bag ripped, as a tree grabbed it. I sent it to osprey and they fixed it at no coast to me besides shipping it there. It is a little bit expensive for a pack, but the customer service and pack are well worth it. I was wishing I had it every ride it was gone, and I was supper excited when I got it pack. If you are questioning whether or not to get it because of price you need to know that it is well worth every penny! One of my best purchases yet! I also use it for hiking now and then which it dose an excellent job at too!

Love this product, took it to Lollapalooza this yea (yes I know not the items intent) but I tell you what, I was jumping, running, and everything in between and didn't even know I had it on. The pack stuck to your back and the water bladder was very conferrable and easy to refill. I have not taken it out hiking or biking but I do highly recommend it. I was able to put a rain jacket, poncho, regular sized water bottle, snacks, 2 cell phones and a charger pack it in. Great item, love Osprey.

I have been mountain biking for 25 years I have used many other brands of hydration packs. This is the best thought out pack I have ever had. Full to the top with water and gear for me and my dog I forget i am wearing it.

I use this as my go-to cycling pack. For years, I used a fairly large Camelbak model, which worked 'ok,' but this pack is light years more advanced. The cycling specific features, like the built-in tool compartments, pockets for my bike pump, shock pump (and even my hand saw), and easy to get to smaller pockets make it extremely useful. The reservoir slides in nicely, the magnetic secure mechanism for the hydration hose is like magic, and the suspension couldn't feel better. It's super comfortable and all the great precision adjustability that Osprey is known for in their larger packs is clearly employed with this pack. I'd recommend this particular model (even at this volume) to anyone.
