Taking beverages on-the-go is an important part of a busy lifestyle but it can be frustrating when a travel mug leaks leaving a stain on a favorite shirt or blouse. The New Contigo Snapseal Travel Mug gives confidence that stains won't slow down the day. With a quick snap of the lid the mug seals for 100% leak-proof performance. Simply push up slightly on the tab to open for drinking. Press the tab back down to completely seal the mug against leaks. The Contigo Snapseal Travel Mug is designed for an easy one-handed drinking experience. All you need to do is pop the top to drink. There's no lid to unscrew or remove-just make sure to snap it closed after you're done sipping to seal the leak-proof lid. However you prefer it your coffee stays hot up to 7 hours or cold up to 18 thanks to Thermalock vacuum insulation.
