Whether you're commuting, hitting the beach for the final waves of the season, or taking a two day bus tour of Amish settlements, take the trip's essentials in the Osprey Momentum 30 Backpack. For your cycling craze, this pack has a Lidlock Helmet Clip, U lock storage pocket, and blinker light attachment tab. If you prefer flip flops and sand, 30 liters of storage holds your towel, sunscreen, water bottles, and snacks with room to spare. When you're off for the weekend, put your toiletries and clean undies in the bottom, and leave maps and your camera on top. This pack keeps going until you've collapsed, and even in your prone position, this daypack is still super comfortable. The EVA foam padded shoulder straps and ridge molded foam Airspace make wearing this backpack downright dreamy. Compression straps, a nylon waist belt, and the adjustable sternum strap help bring down the bounce factor when you're launching your bike off of curbs or traveling over scree fields. If your excursions are more air travel or urban oriented, the dual zippered tech pocket holds both your laptop and tablet, making it easy to access or store your electronic devices once the front boarding door has closed. From a different perspective, this pocket lets you access your technical ties to the outside world without sharing your dirty laundry from the weekend in Vegas, ahem. A zippered top slash pocket features a combination of mesh and fabric organizational options, including an attached key clip. Both the pack and included rain cover have blinker light attachment tabs. Come rain or clear skies, light up the night with your own source of luminescence. The integrated rain cover hides in a bottom zipped compartment when not being used. Side mesh pockets hold your water bottle or tire pump. With this beefy backpack, you can bike, hike, and travel with everything you'd ever want at your fingertips.
