18 oz Callie Tallboy Tumbler

Poor lid design. It drips down my chin when I drink from it. Also, lid is a pain to get off because you have to tighten it sooo much to prevent liquid from seeping out at the lid seam. Doesn't keep liquid hot for as long as advertised.

Keeps my drinks cold for a long time

I loved the size and how it keeps things hot or cold.. i will also start my trip tomorrow and i can’t wait to use my Water cantina!
