MyLarky takes hydration seriously, so she's brought you the perfect water bottle! It's portable, fits in most cup holders, and is just the perfect size without the bulk (17 ounces). Thanks to double-wall insulation, it keeps cold drinks cold for 12 hours and hot drinks hot for 6 hours! Its stainless-steel screw-on lid creates a vacuum seal, and the carry handle lets you grab it on your way to your next adventure.
