CozyCasa HeatGuard Travel Mug Sleeve

I've been through three of these in two years because I keep giving them away and then buying new ones. The first one lasted through daily use at my desk job for about eight months before the neoprene started to fray at the seam. The second one I accidentally left on a radiator and it shrunk about 20% but still worked on a smaller mug. The third one is currently on my winter thermos and has survived a week of below-freezing car commuting. My only real complaint is the colors are not as saturated as the photos—the 'midnight blue' is really more of a dark slate. But the heat retention is genuinely good. I can pour boiling water at 7 AM and it's still uncomfortably hot at 10 AM. The elastic band holds firm without stretching out. For the price, it's a workhorse. Would buy a fourth if they made a burnt orange color.

I ordered this Tuesday night from a truck stop Wi-Fi, thinking it would arrive next week when I'm home. Nope. Showed up Friday morning, before my shift ended. My buddy Dave recommended it for keeping coffee warm on the cab floor, and he was right. My mug doesn't roll around when I take a curve, and the coffee stays hot through a 10-hour stretch. Only thing: the loop is a bit tight on a 22oz mug. But for the price and the speed, I'm impressed.

I bought this thinking all the 5 star raves were bots or paid shills because come on a mug sleeve with this many glowing reviews but after I sewed a little pocket on the side for my tea tag and added a loop to hook it onto my backpack strap I actually have to admit it's decently well insulated and the neoprene doesn't smell like a tire factory which is my main complaint with these things so fine you win I'll give it 4 stars but I still think the 5 star ones are fake.
