Up to 36+ Hours Cold Yes, our hydo bottles are extremely good looking, but they are also slightly heavier than others, to keep our liquids the COLDEST. We use real, true-stainless steel, vacuum insulated, powder coated, and perfectly crafted for an entirely new experience. Rumor has it that we use mythical craftsman mastery while perfecting the flask, and that is why they stay so cold. Quality is everything. Built by Engineers Most hydro bottles do not use high quality stainless steel, the flask punctures easy, they leak, rust quickly, dent easier and most importantly do not stay cold as long. You demand so much. We know. We do too. We've built our bottles using True Stainless Steel Grade Metal, thickest of its kind. Whether you need a gym bottle, bike bottle, or the best sports bottle, this bottle is built to be your last bottle, The Coldest Water.
