A Hydro Flask often conjures up images of campfires or cross-country skiing. But let's face it: sometimes these hard-working stainless-steel water bottles are often just parked on your desk keeping your water cold through that huge morning project or making sure your coffee's hot deep into the afternoon. As much as they love a good adventure, these insulated water bottles, coffee mugs and more make excellent partners in your daily grind. Need to focus on a pile of work? The 40-oz. or 32-oz. Hydro Flask means you have to make fewer trips to the water cooler for refills. The 18-oz. and 21-oz. Hydro Flasks beautifully hold all things caffeinated. But all these sizes, plus our 24-ounce size, are excited to hit the trails with a backpack on the weekend too. If you're looking for a great gift idea, we love wrapping up a Hydro Flask with some women's activewear for the adventurer in your life.
