There's a lot of choice in the "commuter" market and much of it consists of hybrid packs that double up as day sacks, but the Osprey Momentum is an out and out pack for bike commuters. Yes it would be perfectly acceptable as a commuter bag for use on the trains or tube but its feature list is based around cycling. From a high-vis rain cover to an LED light attachment point to the reflective graphics it's at its best cycle commuting, and on arriving at your destination the LidLock that visually dominates the front of the pack gives you a place to stash your helmet.

To date we've found no less than 9 zips and 10 pockets, and that's excluding the 5 main pockets! There's one for the rain cover, a bottom pocket and a front panel "organiser" pocket with, yes you guessed it three internal pockets. Then there's the main compartment pocket with another three internal pockets, or 4 if you include the mesh pocket hanging down but accessed via another zip on the top of the pack. Finally there's another large pocket closest to the back with its own internal zipped pocket capable of taking a full size tablet. Oh, I forgot the two elasticated mesh pockets on the sides and a well hidden zipped side pocket containing a key attachment clip that resembles the pull cord off a talking Action Man.

Holding the collection of zips and pockets together a spacemesh harness, durable fabric and Osprey's characteristic build quality. The AirScape backpanel with its foam ridges is designed to provide ventilation while the expertise Osprey have in making large packs comfortable to carry is evident in the layout, design, and construction of the shoulder straps. At 1.21kg there are almost certainly lighter alternatives but on first impressions it would be hard to beat the comfort and convenience of the Momentum. Whether empty or fully loaded it's comfortable to wear and just in case you want to carry it, say on the tube, rather than wear it there's a perfectly positioned grab handle on the top.

We've yet to put it through a sustained series of commutes but on first impressions it looks like Osprey really have thought of everything with the Momentum. With a list price of £100 and a street price around £90 it's reasonably priced when you look at the build quality, comfort and the sheer number of features.
