HEXNUB Chemex Cozy - For 6 Cup Collar & Handle Chemex Coffee Pour Over Maker, Keep your Coffee Warmer & Glass Carafe Protected

It kept my ~500 ml of coffee adequately hot for the amount of time I needed.For what it's worth, I can brew my coffee and let it sit for ~30 mins (so I can make breakfast). I leave the filter with the spent grounds on top to slow down the cooling. I own a Chemex lid but I don't use it much because I don't want to bother with preheating it (the glass lid is pretty much a thermal sink if you don't preheat it too). After I finish making breakfast, I pour maybe half of the coffee in my preheated cup and the coffee is still hot. I'll probably finish that cup in about another 30-40 mins. By then, my cup is cold but the coffee still in my Chemex is drinkable-ly warm. To me, that's pretty good given that half of the initial heat mass is gone.I got the 8 cup sleeve for my 8 cup Chemex. It fits fine. It's snug but fits. The first couple of times trying to get the sleeve on may feel tricky as the Chemex is oddly shaped. It might have been a little bit tight the first time but I think it's stretched to the right fit at this point. I definitely recommend putting the sleeve on before you brew.The sleeve is nice to have on as it gives me another point of contact that I can comfortably hold the Chemex. I do not feel any heat through the neoprene sleeve. Also, you won't require a coaster or some kind of pad for condensation.You can probably make one of these if you have the skill set and knowledge. And a thermos is probably more effective. I don't have the skill or knowledge and I think throwing a thermos in the mix is just another thing I have to wash for not that much coffee that I need to keep warm for that amount of time. For me, this is a reasonable price for a good solution for the amount of coffee I want to drink in the amount of time I take to drink it.

Hands down this is a must own product for Chemex coffee brewers. I can make a chemex pour over, walk to drop my kids off at daycare, come back and the coffee is still warm. Yes, you'll have to unzip the jacket a bit to see the fill level as you make coffee but oh well, its worth it to keep it warm for an extended period of time.I wish they had a different color/pattern to hide some of the coffee stains which you can see in my photos... doesn't really bother me but eventually it will need to be washed and I just hope that doesn't reduce its lifespan our thermal insulation ability. Even if it does, I'll probably buy a new one or a second one just to have for the future.Love this thing.

I love the look, fit and feel and am looking forward to the insulation benefits (haven't actually used it yet). My only complaint is that the gap at the top of the zipper is larger than I had expected and seems unnecessarily so. To be fair, even the company's photos show it, so I'm not suggesting any deception; it's just a little different in person and up close. It seems like they could have made it slightly less pronounced or even included some kind of clasp at the top. To be clear, the fit at the actual collar is great; just that little piece where the zipper ends seems pronounced.Even with that minor complaint, it's beautiful and good value, and I'm glad for the purchase. The lid is nice to have and it's great that they include that in the package.

the cozy fits perfectly - and it does seem to help keep the coffee warm. i use this every day, and it's held up nicely for months. the lid matches the chemex wood design very nicely too.

I purchased an 8 cup and 10 cup cozy for our Chemex. I wasn't sure what size I needed, but i have two so I got both sizes. They are exactly as expected and fit the glass base perfectly! I don't know why I waited so long to find these. We camp a lot and use our Chemex brewer. This cozy is a game changer in keeping our coffee and tea warm for the second cup. And, I love the color - a soft, modern grey heather.

Keeps the coffee, drinkably, hot or warm for the better part of an hour. Significant improvement over the tepid results of the glass carafe on its own

Liked the design and was easy to put on however it did not keep my coffee very warm

I liked my chemex pour-over but it lost too much heat - coffee was getting cold by the time I was done making it. Preheating the chemex helped a bit, but not enough. Combined with preheating this keeps your coffee warm for something like 30 minutes, so you have plenty time to use it.
