This is a vacuum insulated stainless steel water bottle designed for the days that don't slow down, from the morning school run or commute to the gym bag, the desk, and everywhere after. Available in 16oz, 24oz, 34oz, it's sized to keep up with however your day looks. Double wall vacuum insulation keeps water and sports drinks cold for hours, so it's just as refreshing at the end of a workout as it was when you filled it that morning. The straw lid stays leak proof when the nozzle is closed, so you can toss it in a backpack, gym bag, or tote without a second thought. The 16oz and 24oz also fit in most cupholders, but the 34oz is not cupholder friendly. Not recommended for hot or carbonated beverages. The lid is top-rack dishwasher safe, and most bottles are too (check your color's specific care instructions on the base of the bottle) - easy to clean and refill for tomorrow. The food-grade 304 (18/8) stainless steel interior is made without BPA, lead, or phthalates, so it's a bottle the whole family can trust, from school mornings to weekend workouts. A practical, thoughtful pick for back-to-school, birthdays, Father's Day, and everyday gifting - especially for the students, gym-goers, and on-the-go parents in your life who want a water bottle that actually fits their routine. It pairs well with our Fletcher backpack, Hadley lunch box, or Getaway Bags (all sold separately). 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. Pat/Pat Pending.
