Why does this water bottle do its job the best? It has triple-walled vacuum insulation, which is why it can keep your liquids hot and cold for so dang long!! But no matter the temperature, your bottle won't ~sweat~ on the outside. It also comes with two lids: a stainless steel lid with a carry handle and a black sports cap that lets you conveniently drink water one-handed while working out. It has a wide-mouth opening, which is great for loading in ice and/or lemon slices. The powder coated bottle finish provides a slip-free grip. All caps are BPA-free! Hand wash only though!
Promising review: This bottle is AMAZING! I got the 17 oz one and I am so happy with it. I tell everyone to get one, and I'm purchasing another. I left ice cold water in this bottle in my car when I arrived at work at about 8 a.m. It was a sunny, hot day and my windows were up. At 4 p.m. when I left, I got stuck in traffic and was thirsty. I assumed that it would be hot or at least warm, but in desperation I tried anyways.
The water was STILL ICE COLD! After about eight hours in a sweltering car! I couldn't believe it. I'm sold! The outside is also perfect for decorating with fun vinyl stickers." —Stacey Lynn
