The Salewa Rienza Thermo Stainless Steel 0.75L Bottle in Steel is a double wall vacuum flask that holds drinks hot for up to 24 hours and cold for up to 30. A twist and pour cap lets you serve without unscrewing the lid, and the outer cap doubles as an insulated cup.

• 24 hours hot, 30 hours cold: the double wall vacuum insulation covers a full day on the mountain and an overnight in the car park after it.
• Twist and pour cap: the top pours with a twist rather than a full unscrew, which keeps heat in and gloves on.
• Insulated cup lid: the double walled steel outer lid works as a cup, so a hot drink can be shared without extra kit.
• 18/8 stainless steel: the food grade steel is taste neutral and corrosion resistant, with no plastic or aluminium in the drinking path.
• No exterior condensation: the vacuum wall keeps the outside dry, so cold drinks do not wet the inside of a pack.
• Powder coated grip finish: the textured exterior stays secure in wet or gloved hands.
• 750 ml at 469 g: the flask stands 31 cm tall and carries three quarters of a litre, sized for a day out rather than a desk.
• Free of BPA and aluminium: the flask is fully recyclable stainless steel throughout.
• 24 hours hot
• 30 hours cold
