After some internal debate (mostly due to the price), I finally broke down and bought these S’well bottles from Amazon last month. It was worth it. The left bottle is stainless steel, it holds 17 ounces, and it’s Aquamarine. The right bottle is stainless steel, it holds 16 ounces, and it’s Teakwood. The Aquamarine bottle keeps cold stuff cold and the Teakwood bottle keeps hot stuff hot, so you won’t need to throw away half of your drink everyday because it lost it’s intended temperature (speaking from personal experience). Aside from their exceptional functionality, they also look amazing; especially when bought together. The Teakwood really brings out the Aquamarine doesn’t it? I have them displayed in my room when I’m not using them. If you’re interested here is where you’ll find the Aquamarine and here is where you’ll find the Teakwood. Stay hydrated.
