Oh perfect for my hubby's drinks I send in his lunch.at 69 he's still working a full time physical job at a recycling company that reclaims air conditioning gases, refigerant gases and they also recycle metals. Very labor intensive work for my hubby.I make sure he stays hydrated by sending gatorade or powerade, Arizona grapeade,tang and coolade,sometimes a soda as well. I looked at one of these chilly lunch bags at Sam's Club, it was more than $18!I'm going to bid, I hope I win it for my hubby's lunches! Tukismom
