“These are wonderful bottles however if you have small hands, they are too big for you. Go for the 750ml. These bottles need a grip- dent in the side of them for smaller hands as i have to rest mine on my little finger so it doesn't slip through my hand! But keep drink very cold for over 12 hours.”
“A little heavier than my previous bottle but this is outweighed by the fact that at the end of a 10 mile walk in 25°heat the drink was still as cold as at the start.”
