VaporAir 2.0 7 Liter Hydration Pack Vapor Grey/Blue Me Away / XS-M

Used this for my first marathon and loved it. I was using a camelbak (not the vest kind) which worked fine but left my shoulders feeling sore on long runs. I love how the vest hugs your body. I had plenty of room for my gels etc. the only thing I like better about the camelbak is the quality of the bladder. But I’m not complaining. I can always switch the bladder out.
