Grab Osprey’s Momentum 32 and get on your bike for a ride to work, school, or around town. Even when carrying heavy loads or on big climbs, the mesh covered shoulder straps and backpanel ensure ventilated comfort. LidLock™ helmet attachment keeps your hands free to dig for change at the coffee shop and the blinker light attachment and reflective details provide low light visibility options for early or late rides. Commuting is not a fair weather sport, but a built-in high visibility raincover keeps your pack and gear dry in the slop and a separate lower zippered shoe compartment stores your muddy shoes until it’s time to ride back. Laptops and tablets stay safe in a dedicated top-zip sleeve, and the main compartment has document sleeves and plenty of room for your commuting, school, and work gear. A smaller zippered front panel pocket features mesh organizers and pockets to keep smaller items in their place. At your desk, open the zippered front panel to access the pack’s main compartment where you’ll find an internal document sleeve, mesh organization pockets, and padded laptop and tablet sleeves. There’s also a pair of stretch mesh side pockets for extra storage options.

Solid pack


I've had this pack for a few weeks now and have taken it on a weekend trip to South Carolina so I wanted to write a quick review. This pack is built with quality and well thought out with respect to the materials, compartments, etc. I use it mostly for daily use commuting on public transit and also some light commute biking. The pack is great for that purpose and has more than enough room for my lunch, gym clothes, and all my accessories. I'm glad I went with the 32 litre, its a perfect size. The pack was also easy to use for a weekend getaway and allowed me to pack all my clothes, toiletries, shoes, etc. and could be used as carry-on for my flight and also fit neatly under the seat in front of me. If I had any suggestions/critiques for this pack, it would be that the straps on either side that allow you to tighten the pack down look sloppy and are annoyingly placed and make it difficult to pull your water bottle out from the holster. Also, unless you're some kind of gymnast, there is no way that you can reach to pull your your water out of the holster on either side to take a sip while wearing the pack and definitely not while riding on a bike. Also, I wish there were some way to lock the settings on your straps so that they don't loosen and occasionally require readjustment. Lastly, although I realize the pack is cyclist oriented and I do like the helmet holder, I think it would have been more functional to have a cross-weave bungie type thing (not sure exactly what it's called) on the back of the pack instead of the helmet holder to allow for more versatility to hold a helmet or a sweatshirt, jacket, or whatever else.

Great bag for a daily bike commute


I received this bag as a Christmas gift last year and I love it. I especially love the shoe pocket (sometimes for a change of shoes, other times for a rain jacket), the rain cover, the sunglasses pocket, and the key ring/elastic (no more digging for keys!) It's super roomy - I can easily carry a change of clothes, a decent-sized lunch bag, and a change of shoes, along with all my daily stuff (phone, keys, wallet, etc) with no problems.



Good, but a few fatal design flaws


Momentum 32 I use this pack for 3 month now, not on a daily basis, but often, and just returned from Germany using as my day pack. Understand this backpack was designed for bike commute, but it should be possible to be used a a day pack while commuting to the office and not as a "messenger" bag. While the main compartment is spacious, with or without the secondary compartment used, the very strange side pockets and compression strap design limits the performance and usefulness of the pack. Due to the compression strap the lap top compartment has a limited opening, the compression strap does very little and can not be called a compression strap and the side mesh pockets seem to smaller, even they look bigger than on the Comet 32. The open mesh/nylon design not only limits the stretch and after two uses the mesh is already broken (a normal water bootle - the Comet has the same problem - the mesh quality seems to be a lower quality standard as the rest of the pack & the pack was not overloaded) but it also limits the use of the very small front compartment. The front compartment is poor - the zipper pocket for wallet etc is very small, the two mesh pockets are deep but the top elastic is too loose an items easily slip out. There is not single pen holder. Change the questionable side mesh pocket construction, and add the front organiser from the Comet and we got a nice 27/7 bag. Not easy to keep the pack standing upright. The top carry handle looks and feels thougher than the one on the Comet - I prefer the Momentum 32 version/construction. The carrying straps with the elastic are nice addition and make a heavy load easy to carry. All in all the main compartment and the elastic carry system are the plus of the pack, laptop and front compartment are an addition, but less useful than on other Osprey packs. The side mesh pockets - not sure if I wanna use them while riding a bike - afraid of things falling out - The don't look convincing
