Stay hydrated in style with this Konokyo 20 oz tumbler. It's made of stainless steel with double-wall vacuum insulation, so it keeps your drinks cold for up to 8 hours and hot for about 6 hours—perfect for iced coffee in the summer or hot tea in the winter. The cool matcha green color looks fresh, and the tapered shape fits in most car cup holders. You get two lids: a sip straw lid with a lock to prevent spills (great for on the go) and a simple push-on lid with a slider (handy for hot drinks). Plus, there are two reusable stainless steel straws—one curved for sipping, one wider for smoothies—and even a straw brush for cleaning. The handle is detachable, so you can use it or take it off depending on your mood. It doesn't sweat, so no wet hands or water rings on your table. Take it to work, the gym, camping, or just use it around the house. It's durable, easy to clean, and way better for the environment than disposable cups. A solid, versatile drinkware choice.
