Osprey Momentum 34 Commuter Backpackis rated4.6out of5by10.
Rated4out of5byfromPack Covers All BasesThe difference between my old two section Beaver Tail Style backpack to this one is like night and day and a huge improvement. The expansion zipper allows me to make the pack large enough for towels, shoes and clothes on Monday and then shrink back to everday bike commuting use the rest of the week. I love the front strap pockets although the pockets were not designed with a rectangular iPhone in mind although it does fit. I think an Android phone might be a stretch. The key ring pull inside one of them is a great idea. It's nice to have the pockets and zippers instead of digging through one big open chamber. I can actually find the lights, knife, keys, badge, etc that I stashed away without dumping half the pack out as I did before. I have found the side pocket zippers require two hands to work but that is a minor problem. All in all this a great bike commuting pack.

Rated5out of5byfromGreat packI use this pack to carry workout gear to/from work for lunch time workouts. Also for travel, for packing up all my stuff for driving to a trailhead. Lots of pockets and pouches for the OCD in all of us. Holds a laptop, shoes, and clothes just fine. A little big on the back, though. It's bigger than a camelback, but that's what I have a camelback for. Handle on top and side so I can throw it into the car easily. Shoulder straps can stow away inside so it becomes a clean bag for airport.

Rated5out of5byfromGreat multi-use bagI use this as a carry-on when traveling because you can tuck all the straps in to get it through security or store it in an overhead bin. It works great for that purpose--lots of space and my iPad can slide into one of the protected sleeves really easily. My primary use, though, is as a backpack to commute to work. My ride is only a handful of miles, but it's just long enough that I can't bike in wearing my work clothes (typically business casual)--I got a Pack-It Folder that holds my dress pants and a dress shirt and it slides right into the laptop compartment. Dress shoes, socks, etc. all can go in the main compartment and there's tons of extra pockets for stuff like my wallet, ID badge, U-lock, etc. I keep most of my repair tools on my bike, but there'd be space for those if I needed to--there's enough room that some nights I can stop by the grocery store on the way home to buy a bottle of wine and it fits right down in the middle. I got the bamboo color, which is a nice hi-viz yellow. Added a blinking light to the loop on the back and it's great. I agree with some folks here that the backplate can get a little hot, and I think it rides up your back a bit, but overall it's very comfortable to bike with. I especially like how all the slack ends of the straps loop back onto themselves to keep them out of the way.

Rated4out of5byfromGreat cycling backpackVery spacious commute back pack. My MacBook Pro 15" fits without any problem plus a lot of other things. My only wish is for it to have a place to put a water bottle or my tea mug.

Rated4out of5byfromGreat pack, room for improvementI have had this pack on two trips now and found that the pack is a really well built pack. I love the rain fly built in so much that I find I will never purchase a pack again without one. The Osprey name is the reason I purchased this pack, their warranty is bar none. I travel a lot for work and other packs that did not have pockets for my laptop did ok but I could not fit much in them. This pack makes up for that, there is plenty of room for my large 17" engineering laptop plus my iPad and all the rest of my gear for traveling. Cons: The water bottle pockets are VERY loose and hard to hold a water bottle. Once I get all my gear in the pack is quite heavy and I can not carry the weight on my hips like I would like to due to the fact there is no wide hip belt, instead all it has is a position belt to keep the pack close to your back. This would be the perfect all around pack if it had a wide hip belt that I could use to take the weight off my shoulders. The only other problem I have been having lately (don't know if it is just my pack or not) is the shoulder straps loosen on their own so everytime I put the pack on I have to readjust one of the shoulder straps, this has been very anoying. All in all this is a very well put together pack, the type of quality I have come to expect from Osprey, but there is room for improvement.

Rated5out of5byfromPacked with Features (no pun intended)Great features. I won't go through all of them beacause you can read those yourself, but all perform well. You know how some products you buy have great ideas and thoughts behind them but the execution seems to go wrong. Not with this pack. I commute to and from work everyday and ride a total of 30 to 40 miles per week. I use it to go to the grocery store, to work, to do errands, everything. I love how it opens to a larger size...fits all my groceries. Gallon of milk, coffee creamer, fruits, etc...i will load this thing down...strap it to my back and head out. The load stays put thanks to the cinch points. One issue though... I live in Atlanta and during the Winter I found the bag to be the consummate bicyle commuter pack; however, I have noticed now, since it is getting warmer, that my back sweats like crazy while wearing it. To its defense though...I sweat like a beast.

Rated5out of5byfromNot just a Commuter PackFirst off I am not a commuter and did not get this pack for bike commuting. I was looking for a new weekend trip and everyday backpack that could also double for day hikes and this pack fits the bill. My final decision was between this pack and the Kelty MAP 3500 and it was a difficult decision to make because both are excellent packs but I ended up choosing this Osprey because it looks cooler and more normal to go around with on your back which is what I will be doing 95% of the time. I was looking for a pack to meet a few requirements: able to fit a 17" laptop, hydration bladder compatible, waist strap, at least 32L, double as a school/weekend backpack and also a day trip bag, and lastly be awesome looking. Needless to say this fit the bill quite nicely and then some. Best Features: -You can actually fit a hydration pouch very nicely in the area where the shoulder and waist straps can tuck in. There are loops on the shoulder straps to tuck the tube also. I bought the Osprey hydration bladder because it has a magnetic attachment, simply brilliant. -Straps all tuck away nicely and easily for travel. -Lots of space inside and is also expandable. But the compression straps tighten down so it never looks huge. -outer mesh stuff pocket, perfect for a shell or fleece not just a bike lock. -Included rain cover. Now that is clutch, I wish it was matching color for the carbide pack but oh well. -Dedicated laptop compartment fit my 17" laptop very well with height to spare. Maybe a half inch more on the width but it is pretty snug. You could also fit a nice tablet in the pouch as well with the separate pocket. What it lacks: -I kinda wish it had a better waist strap, padded and bigger. But not a deal breaker. -There's no water bottle pouches on the sides for a nalgene, that really bums me out. -Side pouches dig into the internal space so they are largely useless -The cell phone pocket is pretty small. I don't know exactly which cell phones are supposed to fit in it because it is not square shaped and tapers at the top and bottom. I suppose if your still using your flip phone from 10 years ago it could work. Overall: Very sweet pack and it will be around for many many years. There is not one reason I can see for not getting this pack, it is just fantastic as long as you are willing to compromise on the "cons" like I did.

Rated5out of5byfromGreat packThis is a fantastic pack for more than just biking. I bike everyday and it's great with well thought out pockets/design but the pack is great for a multitude of other things. The only downside is the backpanel gets no ventilation so your back will get very warm and sweaty. On top of the great pack, the customer service is excellent. Osprey is all I'll buy for backpacks after dealing recently with their customer service. Fantastic pack but better service.
