The Hydro Flask 21oz Standard Mouth Insulated Bottle with Sport Cap is a stainless steel bottle for bringing a drink along on your adventure. The insulated bottle keeps cold drink cold and hot stuff hot (24 hrs & 6 hours, respectively). With the sport cap version, I definitely recommend water or sport drink inside. Hydrate to keep yourself going.
