This eco-friendly 700mL borosilicate glass drink bottle for cool liquids has a soft neoprene insulating sleeve, carry handle, and flip out drinking valve with a straw. Drinks keep cooler for longer. The borosilicate BPS- free glass is strong and shatter resistant. Carbonated liquids are not recommended and hand-washing is best. Our Trust logo is printed on the neoprene sleeve in green with a grey top (the colour of brain cancer).
