Radial 34L Backpack

You're the type of commuter that's a biker and, out of necessity, a walker (maybe even a sprinter when that meeting is in five minutes). Panniers just don't do it for you, and you need a lot of space, but you want a backpack that's comfortable and can keep your stuff organized. Cue the Osprey Radial 34 Backpack. When you're commuting on your bike, the Airspeed backpanel and perforated EVA foam harness keeps your shoulders cool while you're pedaling with a loaded pack. The Lightwire framing system gives this pack some backbone for a more comfortable fit. If you're riding over road rubble, the removable nylon waist belt adjusts via the modified ErgoPull system to supplement pack stability.

A top-access, dual-zippered tech compartment stores your laptop and tablet in separate padded sleeves. The main compartment offers document sleeves for lab reports or EBIDTA spreadsheets as well as mesh organizers for your calculator, gum, erasers, and pencils. The LidLock helmet clip holds your helmet when you're not on the bike, and a discrete compartment holds your U-lock when you're in transit. Both the pack and the integrated rain cover have blinker light attachment tabs and a bit of reflective material. Regardless of the weather, clip on your favorite flashing light so motorists have a chance of seeing you.

A hiking/biking family of 7 love it

I've used it several times
6' 4"

Every feature is great and well designed to accommodate a variety of gear and activities. However, only suggestion would be more color choices so we can each identify our own bag at a glance! We also bought a larger Osprey backpack last year, which is a favorite with our son. He has had it through hikes in Montana, Wyoming, Colorado, Arizona, Idaho, California Sierra country and home again in North Carolina. He LOVES HIS pack. Our son-in-law is getting a biking Osprey Raptor 14 with the hydration system for his birthday. He already had an Osprey Daypack plus. Thanks for your great innovations!!
