Say Goodbye to Plastic With These Portion-Perfect Stainless Containers

Klean Kanteen doesn't just make water bottles. The brand also makes vacuum-insulated containers ($30 for 8 ounces; $35 for 16 ounces) to keep contents hot up to four hours and iced up to 12. The silicone seal locks in liquids so you can feel good packing stews or smoothies. If you don't need your foods to stay hot or cold, the brand also offers single-wall containers ($18 for 8 ounces; $22 for 10 ounces).
