21 oz Standard Mouth

Double-insulated stainless steel, to banish lukewarm drinks forever. Designed for everyday adventures, the 21 oz Standard Mouth bottle from Hydro Flask is their mid-range and most versatile product. Small enough to fit in a rucksack side pocket - or your car’s bottle holder - but carrying over 600 ml of liquid, the 21 oz bottle is the perfect companion for your daily travels. Plus, since it’s made without BPA chemicals, you can keep re-using it worry-free.
