My insulated mug came back from a canoe trip actually COLD inside
Last weekend I took my usual Yeti mug on a 6 mile paddle down the Rogue River and left it sitting in direct sun for like 4 hours while I fished. When I opened it, the ice cubes were STILL there and the water was frigid. I honestly thought insulated mugs were marketing hype until I saw that. Has anyone else tested their gear in real conditions like that, or do you just trust the lab numbers? I'm curious if cheaper brands hold up as well.
That tracks with what I've seen. I dropped my cheap Walmart mug off a rock into the river once and it sat on the bottom for like 40 minutes before I fished it out. Water inside was still cold. The outside was scratched to hell but who cares about that. I stopped paying attention to lab numbers a long time ago because a cooler full of ice in a parking lot tells you nothing. Real sun and real heat are the only test that matters.
