Product description

Hydration on the Go

The 21 oz vacuum insulated Hydro Flask is our most versatile medium-sized water bottle and one of our most popular. It is the perfect go-anywhere companion on your busiest days. It fits nearly any size ice cube and is easy to drink from on the go. With a convenient 21 oz capacity and a moderately wide mouth opening, it's great for sports drinks, juice, smoothies or water. It stashes easily in a small shoulder bag, your pack’s side pocket or your car cup holder, and holds enough to keep you going for hours without weighing you down. This flask is as diverse as you!

All Hydro Flasks are made from 18/8 food-grade stainless steel, and the double wall vacuum insulation provides top notch insulation power, keeping cold liquids icy cold for up to 24 hours and hot liquids steaming hot for up to 6 hours.

Hydro Flask is proud that all their products are BPA-free. Look for the H-guy and Hydro Flask logo to ensure you’re getting the market’s premium insulating beverage bottle.

We are Hydro Flask

We’ll keep water icy cold on a hot sunny beach. And serve up a hot coffee on the chairlift ride. We’ll sit patiently by your camp chair with frosty cold beer while you gather wood for the fire. Or keep you hydrated on a hike: ice, water, go. And five hours later, after driving to the trailhead and climbing  2,000 feet, you’ll still have ice and water while you enjoy the view. We’ll bring you hot tea on misty riverside mornings when the steelhead are running, hot cocoa to coax your kids along a snowy trail, and a refreshing sip of “all-about-you” during Saturday afternoon yoga. We’re not just along for the ride. We’re along to help make the ride awesome.

We are Hydro Flask.
