The Hydro Flask Water Bottle is one of the best-selling products in its category on Amazon and REI. That’s no surprise, either. It has a sleek, simple design and is made from high-quality materials. The Hydro flask comes in both standard-mouth and wide-mouth options, plus a vast variety of sizes, designs, and colors. I have four: a hydro flask wide-mouth in 32oz, two 24oz standard mouth bottles that slide easily into cupholders, and a small 16oz bottle. All of these options are made from 18/8 food-grade stainless steel and have a slip-free powder coating that stops the bottles from sweating and makes them dishwasher safe.

The double-wall vacuum-insulation design ensures that the liquid you put in stays at the same temperature for a long time, whether it’s ice-cold or piping hot. This technology is called TempShield and is unique to the Hydro Flask Water Bottle.

I found the EcoVessel The BOULDER Water Bottle during my time as a retail buyer in a climbing gym. I fell in love with the BOULDER because I simply adore loose leaf tea. Instead of packing my tea leaves in a strainer, I could throw them into this reliable water bottle, pop in the strainer, and add my hot water. Voila! I’ve had this bottle for years and alternate it with my YETI Rambler, depending on whether I’m drinking bagged or loose leaf tea. The 18/8 stainless steel double-wall vacuum insulation keeps iced drinks cold for up to 60 hours or coffee hot for 12 hours.

The entire lid opens up to a wide mouth bottle size but there is also a small screw cap that unveils a small mouth drinking spout lined with silicone so you don’t burn your lips on piping hot liquids or freeze them with an icy drink. The slim three-inch diameter bottle fits most cupholders making it a great travel bottle. Mine goes with me to work, the gym, the slopes, and all over. If you ask me, this might be the best insulated water bottle available.
