Editor's Notes

September 05, 2019:

They may cost a pretty penny compared to many standard water bottles, but Hydro Flasks are guaranteed for a lifetime, or 100 years, so you can purchase yours with complete confidence. They come in many sizes and lid designs, so you’re sure to find one suitable for a day at the office, a day hike, or a morning cup of coffee. Their insulated design keeps cold drinks chilled for 24 hours, and beverages like coffee, tea, and cocoa hot for up to six hours.

Joining the selection in today’s update is the 64-Ounce Wide Mouth, which conveniently can hold your full daily water intake, eliminating the need for refilling every couple of hours. Its wide mouth accommodates most backcountry water filters, so it’s a good choice for taking camping or on a day hike where you might need to fill it up again. Its cap features a flexible strap with stainless steel pivots, so it’ll move easily with you.

For a selection that’s certainly great for holding water – but also well suited for keeping carbonated drinks fresh – look to the Wide Mouth Growler, which comes in 32- or 64-ounce sizes and features double-wall vacuum insulation and rust-resistant materials. If you prefer a selection with a straw, you can’t go wrong with the Sport Cap S21ST001, which can easily be used one-handed and is great for use when you’re jogging or cycling.
