iLifer Insulated Double Wall Stainless Steel Narrow Mouth 750ml Bike Water Bottle Red

I Bought two, and these water bottles insulate wonderfully. Living in Texas it is HOT, but these babies kept the drinks cool for several hours with ice still in them. I've had to moderate how much ice I put in for my kids because it won't melt...definitely a good thing. The only reason they are not getting five stars is that the color finish on the blue bottle started peeling off after a few runs through the dishwasher, also the caribeaner is cheaply made and broke within a week, but that wasn't what we were looking for anyway.
