Qwetch and designer Lou Ripoll have collaborated to create an exclusive "Arty" model with a colorful and artistic pattern inspired by Lou's creations. This vacuum flask is perfect for taking your favorite drinks with you during your daily activities, from the gym to the office and outdoor walks. The double-layer 304 stainless steel (18/8) and silicone cap ensure total leak-proofing and optimal thermal retention for up to 12 hours for hot drinks and 24 hours for cold drinks. The model is also BPA-free and easy to clean thanks to its BPA-free PP5 structure.
