The Travel Flask collection has been upgraded to meet every need during your daily activities. Travel Flasks are an essential accessory on the way to work, for a walk and to the gym! With a compact design and curves that make it easier to hold and offer a unique design. The 18/8 stainless steel construction inside and out offers maximum protection and unchanged flavor of the drink in every sip. The double-wall, air-vacuated insulation keeps the drink cold for up to 24 hours and hot for up to 12 hours, while the outer wall keeps a constant temperature without "sweating" for a comfortable grip. The 100% leak-proof cap protects against any leakage, while the variety of sizes (350ml, 500ml and 750ml) and the unique designs with high-quality printing and renewed shades cover every preference. The Travel Flasks are part of the Save the Aegean collection, supporting their ecological message through packaging made from 100% recyclable cardboard, BPA-free. Each purchase contributes to the efforts of the Archipelagos organization to protect the Aegean seas.
