Meet the Simple Modern Trek Pivot - the 30oz and 40oz insulated stainless steel water jug we designed for the gym bag, the trail, and the outdoor days that need more than a sip of water to keep up. We made it for the daily grind. Food-grade 304 (18/8) stainless steel keeps water cold for hours, from the morning workout through the afternoon errands, and the comfort handle makes it easy to carry from the car to the trail to your desk. Interchangeable straw and chug lids mean you can sip on the go or pour fast after a workout - one bottle that adapts to however you drink. Sized to fit most car and gym bag cupholders, it goes wherever your day takes you. A silicone boot helps protect the base from the dings and dents that come with tossing a water bottle in and out of a gym bag, truck bed, or locker. The bottle, boot, and both lids are all dishwasher safe for easy cleanup and made without BPA for a safer daily choice. The Trek Pivot comes in a wide range of on-trend colors and multiple sizes, so you can pick the capacity that matches your day - a 30oz for the desk or gym bag, or a 40oz for the long outdoor days and workouts when refills aren't an option. A practical, thoughtful pick for birthdays, New Year fitness goals, and gifts for the gym-goers, hikers, and outdoor lovers in your life. Pairs well with our Rally Protein Shaker and other Simple Modern drinkware for a coordinated set. Every Simple Modern product is thoughtfully designed for the way your day really looks - with care put into the everyday details and on-trend style. So you can feel good about your purchase and maximize what your budget can do. Patent Pending.
