Rated 5 out of 5 by from Way better than those blue mugs everyone has You know those blue mugs that everyone has, the super light ones that people always bring on their camping trips. They are durable and light, sure, but try picking them up after adding hot water to them -- you can't. They burn. What's the point of making tea on a cold night when you can't even pick up the mug until the liquid inside is cold? There's no point. This tumbler solves that issue. The insulation does what it's supposed to do, namely allow me to pick the thing up right after pouring hot water inside. It's also small and light enough where I brought it with me on a three day backpacking trip and had no issue with space and weight.

Rated 5 out of 5 by from And This One is Just Right. I bought a 10 oz insulated cup (another brand), and it was uncomfortable to hold. I bought a 4 oz insulated cup (another brand), and it was too small unless you want only espresso. Then I purchase this - and as Goldie Locks said; "this one is just right". I love it - easy to clean, easy to hold and it just right for most drinks.

Rated 5 out of 5 by from Awesome mugs! The double walled cup helps keep your beverage temperature stable; a little chilled with some bourbon one evening around the camp fire or hot coffee in the morning with breakfast. Small and light enough to stuff into my pack, easy to clean and the sip-lid is a nice bonus...

Rated 4 out of 5 by from Handy for summer cocktails I bought these to enjoy cold cocktails on summer evenings out on the deck. Does a decent job by itself, but does much better with the lid on at keeping things cold. Be careful--the sippy lid allows the drink to come out much faster than you'd expect. Lightweight and handy.

Rated 4 out of 5 by from Nice camp coffee mug This is a really nice, compact thermal coffee mug. Perfect for camping, maybe even backpacking. I certainly will use it on my next trip.

Rated 5 out of 5 by from Perfect for Aeropress I've used this cup almost exclusively with my Aeropress coffee maker. I bought it because my previous travel mug was around 16 oz, which was quite a bit too large for an Aeropress cup of coffee. This one is just the right size. It's compact and fits well in the hand. I wouldn't have thought about it, but I really like the polished interior. It makes it super easy to clean. Now for some of the caveats: It keeps my coffee hot for long enough (especially for the small size), but since the lid isn't insulated, it won't stay hot all day like some travel mugs I've used. Also, the lid doesn't have any kind of stopper, so if you're not careful, it can spill. Overall I think this is perfect for my use with the Aeropress. It would also be perfect for a short Americano, a cup of tea, hot chocolate, etc.. It should also work well for summer cocktails or a glass of wine... I see myself using this cup a lot at home and at the campsite. Cheers!

Is this mug spill proof? Can I put it into my bacpack with the drink inside?

Asked by: Aysel
This tumbler is not spill proof. The lid has two holes that cannot be sealed, so it has the potential to spill if it is tipped over.
