There are backpacks you can use on a bike and there are backpacks designed specifically for use on a bike. The Osprey Radial 26
is definitely the latter.
If you’re serious about getting gear from home to work and back home again, daily, on two wheels, you can’t go far wrong with this little gem (probably should call it an ‘emerald’ though due to its bright green color).
The team at Osprey
really seem to have drawn up a list of the most important things you need when commuting on your bike, then nailed each and every one of them..
