We added extra insulation for maximum performance in our new and improved Triple Insulation Technology. The Boulder has been tested to keep water cold for 36 hours and retain heat for about 12 hours. Use it for water, tea, coffee, soup or anything else you want to keep with you. Its tight screw on top will keep your drink securely inside, where it belongs. It has a wide mouth to easily accommodate ice cubes and a convenient drinking spout. The Boulder is a sturdy, high quality, stylish bottle for the office, tennis courts, golf course, on the trails... anyplace, anytime. Feel good knowing that our 100% recyclable bottles are BPA-free, made from the highest quality #304 stainless steel and are designed for safety, ease of use, and convenience. Accept no substitutes for an original Eco Vessel stainless steel bottle.
