Ultraspire 500ml Soft Flask Straw Bite Valve Handheld

This is a collapsible SoftFlask that carries 500ml of fluid.  The unique shape allows this SoftFlask to slide easily in and out of a hydration pocket.  Comes with a larger diameter top to fit ice cubes in and keep fluids cool.  Features a silicone Sheath Bite Valve.  This flask gives me lots of ideas!
