A very cleverly designed hip pack for runners or walkers who need to carry their phone, and a bottle of water with a little room for a snack and some cash for a post-run pub session. Engineered to fit the female form, the Osprey Duro Dyna Belt with Flask Trail Running Pack, the Duro Dyna Solo for short, is built to provide bounce-free stability and comfort. This little pack carries enough water for a training run, and works great for staying hydrated between aid stations on citizen races. Walkers and runners will appreciate that in addition to featuring just enough storage for the necessities, this has a touch-compatible phone pocket... no need to fish a phone out of your bag to check a map, change a playlist, or check a timer, touch compatible with visibility while still stowed in its pocket! A comfortable and elastic hipbelt, a women's specific size and fit, and an included 570 ml BPA-free bottle, this little running pack is designed to keep you moving, whether you're running around town or hitting a more challenging trail. And if you're looking for the holy grail of hands' free mobility, something that allows you to tote water, wallet, and phone when you're out and about? This neatly fits that travel and errands niche, not too big, not ridiculously tiny, just the right size for town and trail.
