The Byron are travel mugs from Contigo. Byron is a sturdy, vacuum-insulated double-wall drinking mug for hot drinks (up to 7 hours) and cold drinks (up to 18 hours). The stainless steel Byron mug is leak proof thanks to the patented SNAPSEAL technology and comes with a special reservoir so you can sip your hot drink. Also, drinking is conveniently one-handed thanks to the easy lever (slide up to open or down to close).
