re: Latest YETI Ramber knockoff - Ozark Trail tumbler 30oz @ $10 & 20oz @ $8

I picked up a koozie and a 30 oz a few weeks ago. Both work great. I use it for coffee while I'm at work, and it starts warms until noon. It doesn't keep it warm as long as a thermos, but seems to keep it warm as long a my contigo insulated mug, even with the gap in the lid.

The koozie seems to work well. But it's been winter, so it hasn't been fully battle tested. It's loose on narrow bottles, but seals good on cans and Sierra Nevada bottles. A considering in the rope that often accidentally picks up the wrong beer, it's something I'll use.
