We take hydration very seriously here in Texas in the summertime, so my boys always carry an extra drink.
My boys are back at school, now, and brought with them new water bottles.
They love their new water bottles. They're from Klean Kanteen, hold 27 ounces and they're carrying them in these Built bright red neoprene insulated totes. I just pack the drink with ice in the morning and it stays cold for a few hours.
On the back of each carrier, I wrote a son's name with a black Sharpie so there's no confusion about which bottle belongs to which son.
I like knowing I'm keeping my boys safe and healthy, and they like how cool the bottles look.
