The Cello Beatle 1000ml is a double-walled, vacuum-insulated stainless steel flask explicitly designed for an active lifestyle. It features Thermo-seal technology that provides excellent heat retention, keeping beverages hot or cold for up to 12 hours. The flask stands out due to its integrated carabiner loop lock built directly into the cap, making it exceptionally easy to secure onto backpacks or carry during outdoor trekking, gym sessions, and daily travel.
