Thanks all for the responses!
I am thinking of going with the 18 oz for the 2 smallest kids. Would I be ok with a 27 oz for my 8 yr old, or better with the 18 oz?
Can these go into the dishwasher? Do they dent easily?
I am wanting to get some Klean Kanteens for my family.
I am thinking of going with the 27 oz for the adults but am unsure which size for my 8, 6, and 4 year olds. What size should I be looking at for them?
Also, do I need a cover...
