I'm going to retire my 15 year old Sheetz travel coffee mug. Slick callused hands make it hard to hold now, and I'm sure years of drinking hot coffee from the plastic liner haven't been good for me. Plus, I dropped it and now it wobbles. New mug has to have a handle I can actually fit my hand in (my hands are not small) and fit in the LC cup holder. What are you using? Yeti wants a kidney and rtic seems to be made for alien hands. This is highly important stuff right here.
