Hydro Flask says

Keep life moving with our 21 oz bottle and Standard Flex Cap. It stashes easily into a small shoulder bag, your pack’s side pocket, or your car cup holder, and holds enough ice cold goodness to keep you going for hours without weighing you down. No wonder it’s one of our bestselling water bottles.

Our Verdict

Hydro Flask’s 21 oz Standard Mouth with Flex Cap is great for both hot and cold drinks. With a capacity of 621ml this is a decent sized flask that will keep drinks warm for up to 12 hours. In summer it can work for up to 24 hours keeping your drinks cold too. The TempShield insulation allows the bottle to retain a slim design, making it practical and versatile.

The slim design makes it easy to slide into the side pockets of your pack or to place in a bag when you’re commuting. The simple, effective screw top lid makes it really easy to use.
