Take on any workout, adventure, or volleyball league night with the Hydro Flask Wide Mouth Bottle. Made of stainless steel and double-wall insulation, drinks will stay cold up to 24 hours and hot for 12 so you can go that extra mile, hit that extra rep, and go for one more round. The large, wide mouth opening makes it easy to add ice and you can get yourself that life-giving gulp. Show off your custom design against the vibrant backdrop of the Color Last powder coat that also provides durability and sweat-free experience.
