Disclaimer: I received an Amphipod PureRun™ Minimalist Hydration Vest to review as part of being a BibRave Pro. Learn more about becoming a BibRave Pro (ambassador), and check out BibRave.com to review find and write race reviews.
There is also no need to stress about properly cleaning the liquid containers like one does with a typical bladder hydropack, as the two 12oz bottles are so easy to clean. The bottles (flasks) also stand up straight in the refrigerator. Please note: If the bottles are left unattended, small humans may end up packing them in their school in lunchboxes without permission.
The vest is very light and breathable with a mesh fabric and a Lateral stabilization system, which provides bounce-free stability. The bottles are very easy to use, while running, so long as both hands are free (must open the jet-squeeze cap).
I am a huge fan, so expect to see more selfies with me in this vest!
