  • Great backpacking coffee cup
After reading reviews from a plethora of backpackers, almost all pointed to this mug as the best value backpacking mug, so I thought I'd give it a try. It is very lightweight which is important to me. The koozie means the cup isn't too hot to hold. The spill-proof lid is actually spill-proof. I turned my cup of hot coffee upside down to test this and not a drop spilled. It also won't burn your lips like a metal mug will do. I like to mix coffee with hot chocolate and the lid allows me to just shake all the ingredients together without worry of a mess. I also like that the inserted mug is also a measuring cup with more detail than my backpacking stove. Hence, this mug also makes cooking easier. The handle is floppy fabric. This may seem like a negative quality, but I don't think so. It still provides security when I slide my hand through it to hold the mug without adding real weight or bulkiness. I would NOT recommend using it to clip your mug to the outside of the pack. That will only secure the koozie and not the mug. You could risk the mug sliding out of the koozie to your dismay when you arrive at camp sans cup. That would be very sad. So, I toss it in my pack. While in my pack, it serves as a the case that holds my headlamp. I am very happy to have purchased this as my backpacking mug. In truth, I like to bring it with me on all my travels. ... show more

  • Can’t beat it
Color: Heathered Green
This is the perfect cup for backpacking. It is super light, keeps things hot, can be used as a measuring cup, looks nice and a great price!

  • Extremely light cup with measurements!
Color: Heathered Green
I recently picked up this camping mug, and it quickly became my go-to for all outdoor adventures. First off, it’s incredibly light, which makes packing a breeze – I barely notice it in my bag. What really sets it apart, though, are the measurement lines inside. This little feature has been a game changer, whether I’m making coffee at the crack of dawn or boiling water for a meal; I don’t have to guess how much liquid I’m using. It’s made cooking on the trail so much easier and more efficient. On a recent camping trip, I actually used the mug to measure water for a small batch of trail-side oatmeal for the whole group. We didn’t have a proper measuring cup, but this mug saved the day. It’s those little things that make it a must-have for any camping kit. Plus, its sturdy design held up to some pretty rugged conditions. If you’re looking for a reliable, lightweight, and multifunctional camping mug, this is the one to get! ... show more

  • Great 17oz mug, even for small hands!
Color: Blue
I really like this mug. It's light and easy to clean. The insulated cozy does a pretty good job of keeping my coffee warm, and I really like the flexible handle. One thing I will note is that I drink out of it with my whole hand through the handle, gripping the mug itself. I have very small hands, so the handle actually allows me to hold the cup comfortably without worrying that I'll lose my grip on it. The lid seals surprisingly well for a non-screw on lid. I have to make sure the drinking tab is open when I put the lid on with the mug full of hot coffee because otherwise the air pressure won't let me put it on all the way. I've done some trials of turning it upside down full of hot coffee and not a drop of leakage! I've noticed that when I first got it, the cup sat very, very snugly in the cozy, but over a few weeks of use it's loosened up. One reviewer said that they clipped it onto the outside of their pack and then the cup fell out and they lost it, and I agree that that is a danger. I think I'm going to add a bit of nylon webbing with a patch of velcro on either end to loop over the lid, so that I can clip it to the outside of my pack without worries. However, it also fits perfectly in the side water bottle pockets of both of my packs... so maybe it'll just live there. Love how much liquid it holds and it looks cool. Also, the plastic of the mug itself doesn't seem to take on the smell of what was in it, which I really appreciate. ... show more

  • Pretty Nifty......
I got this cup, along with the Coffee Rocket. Simply becuae they nested inside of each other. Super convenient and space saving. The cup has a tight seal at the top, along with a sealed sip-hole. When the top is closed, it's closed. Measurements on the inside transparent cup were convenient and the sleeve kept my coffee warm. Now I said warm. Not hot. The coffee water is literally boiling from a hiking stove to make the coffee. Sorry, but it doesn't take long for a hot beverage to cool down. That's the only negative, but it's still my go-to coffee cup for my setup. Good product......reasonable price.....ease of use and clean up. ... show more

  • Good price on a popular mug
Color: Heathered Green
Thank you Amazon for selling this item a bit cheaper than in popular hiking stores, also offering this color of green which is not available in stores right now. Since I have almost everything for hiking, I am surprised I didn't try this cup already. Now I see why it is popular. It is super lightweight. The plastic cup comes out of the cover if you like. The cup has measuring lines on it. The cover is attractive and has a handle, which is made of a strap so you can flatten it down for packing. The top is removable and has a flap lid. You can make hot coffee in the cup and hold it without burning yourself. It keeps the hot coffee warm for longer than a cup without a lid (but not as long as an insulated thermos of course). It is very pleasant to be at camp and have the feeling of a normal mug. In summer my favorite backpacking mug has been the sea to summit x mug which flattens down. But for winter backpacking I prefer this mug because it keeps the coffee warmer long enough to drink it. ... show more
