    wow what a great bottle! I put ice and room temp water in it at 8 am. drove to Manteca, ca and left it in the car (104*), till 5 pm and the water AND ice were still in it and was sooooo ice cold my fingers were freezing! not kidding either. my service dog, eli was loving the ice cold water after a HOT day in Manteca. cap was leak proof and closes and opens with no problem.
    thank you,

    Bought one for me and really enjoyed it. Makes me drink more water while doing life. This bottle made my wife jealous so I just purchased her one. Make sure you get the half twist cap too!

    Same GREAT Thermoluxe quality and performance, but I’m loving the extra space! These bottles can’t be beat and the bonus for me is they are dishwasher safe, (I’ve been cleaning mine this way for almost 2 years!)…no more late nites at the sink or early mornings rushing to clean my bev bottle!

    I will be so thankful when the following enhancements to the 20 oz. bottle arrive:
    *white bottle
    *half twist caps in more light colors..
    I use my bottles 24×7 and lighter colors and the half twist cap in light colors, incl the new lavender are so helpful when it’s not bright and sunny where I’m using the bottles.
    ABBA!! (Absolutely the Best Bottles Around!)
