INSULATED BOTTLE WITH STRAW, HANDLE & SILICONE BASE: The Mesa Loop pairs a covered straw lid with a built-in handle and a silicone base for soft landings, going from car to desk to gym bag without a free hand to spare. Grab and go with just a finger. LEAK PROOF COVERED STRAW: The contoured straw stays covered and protected when you're not sipping, and the lockable lid is leak proof when closed. Not intended for use with carbonated beverages. CUPHOLDER FRIENDLY & EASY TO CARRY: Both the 24oz and 30oz are sized to fit most car and stroller cupholders, with a loop handle that makes it easy to grab on the way out the door or clip to a bag strap. INSULATED & DISHWASHER SAFE: Double wall insulated, food-grade 304 (18/8) stainless steel keeps water cold for hours, from the morning commute through the afternoon workout, and the straw and lid are top-rack dishwasher safe. GIFT-READY FOR EVERYDAY & TRAVEL: A thoughtful pick for birthdays, back-to-school, and everyday gifting - pairs well with our Simple Modern Ellis backpack and Hadley Hard Shell lunch bags (sold separately) for a coordinated set.
