The Under Armour hydration bottle line from Thermos was built with the active athlete in mind. Athletes need to perform their best, and that starts with proper hydration. The Under Armour 64-ounce hydration bottle features double wall foam insulation to keep drinks cold for up to 12 hours. The carrying handle has integrated fence hooks and also folds down to conveniently nest in place when not in use. The push button lid is easy to operate with one hand and includes a locking ring to keep the lid secure during transport.
