GSI Outdoors Infinity Backpacker Mug I Lightweight, BPA-Free Coffee Cup for Travel, Camping Gear, Backpacking and Outdoors - 17 oz.

The first thing I did when I opened the package was filled it with water and turned it over. Luckily I didn’t fill it with soup and put it into my back pack. Leaks like crazy

Light weight, 3.75 oz on my scale..no burnt lips or hot fingers. Comfortable to hold. Reasonably effective keeping the drink warm to hot. Doesnt leak, nice snug fit, both lid to cup and cup in cozy. Measuring ml marks are nice too.

It leaks through a small hole in the lid that I think was probably put there to act as a vent to prevent “glugging.” There is a rubber bump on the cover tab that is probably supposed to seal this hole, but even though I tried several times, I couldn’t get it to seal. Too bad, because the rest of the mug is a cool design and good quality. I had to send it back, though, because I needed one that wouldn’t leak when placed on its side.

This is the 2nd mug that I bought of this brand. I liked mine so much for backpacking (from a recommendation of a friend) that I bought one for my boyfriend. We tested them out by flipping them upside down and there was no leaking. There are also measuring lines on the inside of the cup.

Used it over the weekend camping in weather where 26 F was the high and 14 F was the low. This little mug kept my tea warmer than expected and I had to actually wait a good 20 minutes or so to be able to drink out of it. I was really surprised because with it being so cold outside I was expecting the mug to cool quickly. I love the soft handle and koozie as well. Really well made and it made packing easier without having to fuss with a hard handle as this one could compress saving space but it was there to clip to my pack with a carabiner when needed. I would definitely recommend and would purchase again.

This is a smart design and we loved it. The interior plastic cup is easy to clean and has measurements on the side which was incredibly helpful. It stays cool to the touch when there’s a hot liquid inside. The top works great and is quite spill resistant.

light, comfy to hold. measuring lines are handy AF! Plastic doesnt get to hot. Keeps coffee hot long enough. Word!

Love this color. Have not seen it in any store I go to.

I like this mug mostly. The one I got does not completely seal. It drips from the mouth piece when it has liquid in it and I clip it to my pack.

It’s a good little cup
