Food grade stainless steel double walled vacuum water bottle (500ml).
Main advantage over plastic bottles is that this doesn't have BPA or those other gender bending chemicals found in plastics which can leech into the drink over time.
Bottle can be used for water, fizzy drinks, hot drinks or mixing protein shakes. It keeps the drink cold on a hot day, or hot on a cold day, as the case may be.
I use this during sports and gym workouts.
Lid is very secure and doesn't leak even when thrown around in a sports bag.
These are normally £9.95, so this is a good price.
Free delivery for orders over £20.
