Why should I buy a Hydro Flask?

Hydro Flask's insulated products keep your hot drinks hot and your cold drinks cold all day long. This means you can sip hot coffee after making sunrise powder turns in the backcountry. Or have hot tea waiting for you when you return from a cold run or nordic ski adventure. You can also have ice cold water after several hours in the hot sun! Keep your beer cold while you raft the river. Enjoy crisp, cool lemonade after shredding your favorite mountain bike trail. Pack a picnic and keep your wine chilled until you find the perfect place to settle down and watch the sunset. With Hydro Flask keeping your favorite drink at the perfect temperature, the opportunities for adventure are truly endless.

Hydro Flasks are made with 18/8 food grade stainless steel, so the flavors of your current drink won’t linger or contaminate your next drink. All you need to do is rinse your flask with hot water and it's ready for a refill. There are no linings or coatings that will leach into your drink or give it a metallic taste. Hydro Flasks are BPA-free and recyclable, and they come in a range of sizes and bold colors, with accessory lid options for a refreshing and enjoyable drinking experience.
