Contigo Byron is a thermal mug characterized by a leakproof spout, temperature keeping for a long time and modern design. The snapseal system patented by Contigo provides an effective protection against spills. The mug is handled with one hand, which increases the comfort and safety of use e.g. while riding a bicycle or driving a car. To open the mouthpiece, just move the lid up and to close it - move it down. It's simple and effective - no more spilled tea or coffee! Due to the design with double, vacuum insulated walls, the mug has very good thermal properties. The high temperature of beverages is maintained for up to 6 hours and the low temperature for up to 12 hours. So now your favourite beverages can accompany you during short or long expeditions, even in difficult weather conditions. Another feature of Contigo is durability. The combination of stainless steel and food-safe plastic make the mug resistant to dropping and impact. The rubber band guarantees firm grip.
