Even the world’s clumsiest person couldn’t drop this mug enough times to break it. Chuck it in your bag with peace of mind that it won’t leak or get damaged by any bumps along the way. With a handy self-sealing trigger action, you can sip away as much as you like without having to open or close the lid. If you want to keep it open, there’s a locking button on top of the lid.
