The Boulder Insulated Water Bottle is our flagship thermal hydration vessel that will keep your beverages hot or cold all day long. Made from food grade 18/8 stainless steel and featuring our signature TriMax® ® triple insulation technology, it’s vacuum insulated and tested to keep liquids cold for 36 hours and hot for up to 10 hours.
The Boulder features a food grade stainless steel removable strainer for tea and fruit infusion. The strainer will also work well as an ice dam to keep your ice in the bottle instead of your teeth. The Boulder includes a multi-lid top with a wide opening for filling and a narrow mouth for drinking and is interchangeable with our coffee and flip straw tops. The two-piece lid includes an integrated carrying strap and its secure leak-proof seal will keep your drink inside the bottle where it belongs. It’s available in a variety of colors and styles in our durable powder coated finish or in a stainless steel finish. Your bottle won't sweat and will fit most cup holders. Toss this insulated bottle in a tote bag, bring to yoga or hit the trails. Whether you are at your desk or running errands around town, the Boulder will keep you hydrated.
