Each flask, regardless of the size, has a heavy weight cotton canvas cover with a BPA free, leak proof, and airtight liner within.
These canvas canteens and flasks are USA made using rugged cotton canvas construction and expel oxygen to preserve the flavor and quality of fine wine (just in case that's your drink of choice!)
The ‘Flask and Shot Glass’ can be easily tucked into your purse, backpack, or back pocket. Just remove the shot glass, pour yourself a sip, and sit back and enjoy. Perfect for just about any occasion!
The larger canvas canteens can hold up to 750 ml (a full bottle of wine) or 25 oz of water or your favorite beverage and include an aluminum carabiner so you are able to attach your canteen to your belt, backpack, bike, purse or market bag!
Care for canteen/flask: Rinse the liner or use a bottle brush with warm water and a bit of dish soap. Wash exterior with soap and water and let air dry completely.
