On most mountain adventures we take at least 32 oz of water. This bottle is perfect for our big mountain adventures where light packs are key, but hydration needs are high. We especially loved the large capacity insulated bottle that kept our water cold as we’ve come to expect from our Hydro Flasks after a long, hot approach to rock climb. There is nothing quite like a drink of ice cold water after a long sunny hike. Compared to the warm or even hot water that we’d normally get with the plastic bottles normally used on longer hikes. Compatible with most backcountry filters you’ll be set once summer backpacking season hits. Hydro Flasks makes a few different lids to suit your needs, we like to swap between the standard and straw lid depending on if we are at the desk or in the backcountry.
