Made from food grade 18/8 stainless steel and featuring our signature TriMax triple insulation technology, this vacuum insulated water bottle is tested to keep liquids cold for 90 hours and hot for up to 18 hours. The Boulder insulated water bottle 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 Reflecta Insulated Lid which keeps your drinks insulated for longer and ensures your drinks don't touch plastic, and features a dual opening lid design with a wide mouth for easy filling and cleaning and a narrow removable soft silicone lip for comfortable and hygienic drinking. The Reflecta Insulated Lid is also interchangeable with our coffee and flip straw lids. The dual opening lid includes an integrated sturdy, silicone 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 colours and styles in our durable powder coated finish or in a stainless steel finish. This insulated water 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.
