But the best insulated bottle the brand makes is the MicroLite 500 ($28). GSI Outdoors dedicates an entire section of its website to all things insulated. The Hydro Flask’s Standard Mouth is easily the bottle we reach for the most often as we head out the door. While it also comes in 18- and 21-ounce sizes, we like the 24-ounce best for most activities. Also, being on the skinnier side, it fits in most cup holders and pack pockets. Our testers raved about this bottle for its great insulation and lineup of more than 12 fun colors. We will note that even the best has a limit, and dropping the Standard Mouth bottle from a good height is liable to lead to some dings.

The brand’s double-wall vacuum insulation and pro-grade stainless steel are designed to maintain drink temperatures for hours without altering taste - an impressive 24 hours of cold and 12 hours of heat retention.Īnd we found during testing that this bottle is pretty durable as well, thanks to its powder-coated exterior. There may only be so many ways to craft an insulated bottle today, but Hydro Flask hits the nail on the head with this one. Hydro Flask’s Standard Mouth bottle($40) won out as the best insulated bottle, with a massive following both in the GearJunkie offices, as well as with adventurers abroad. Sometimes you don’t want to mess with the OG.

And we evaluated each on factors like insulation, shape and volume, durability, and price. For this review, we looked at water bottles that have some form of insulation (whether stainless steel construction or otherwise) and a good-sealing cap or lid. Plus, having a reusable water bottle is great for the environment. Insulated bottles are designed to keep cold liquids colder longer (and hot liquids hotter) and are usually higher quality and more durable than their plastic counterparts. If you’re looking to purchase a water bottle for outdoor adventures, an insulated bottle should be high on your list.
