We designed the Ultralight Nesting Bowl and Mug with a very low center of gravity and a secure Sip-It top, so you're less likely to spill hot beverages and food. This ultra-stable, personal food and drink solution is designed to nest within our nForm Dualist Cook sets for maximum packability. Low profile/low center of gravity design and Sip-It top work to virtually eliminate spills. EVA foam insulated sleeve and Sip-It top keep drinks hot.
