Keep your fluids cool with the Amphipod Hydrafoam Jett-Lite Thermal 12 and 20 oz Handheld.  The insulated removable sleeve holds an ergonomically-shaped 12 and 20 oz bottle, while a small zipper pocket on the handstrap provides space to hold gels, keys, or phone (iPhone5/5S and similar-sized phones).  Perforations on the sleeve and soft materials against both sides of your hand make this handheld a great choice for comfortable and quick hydration on short to medium runs.
