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

Hes a pretty nice mugs I like the fact that you can slip them out and use them as a measuring cup. And the insulation keeps hot drinks hot four the period of time that they need to be kept hot in order to finish a cup of coffee. If theres any complaints the handles are a little loose but stick your hand through it and grip the Cup itself and works fine. Overall a good buy great for camping.

Great size. Lid seems to fit well. Large enough to eat out of if need be. A nice option. Excellent insulating quality and easy to handle. The two down sides for me is that they dont nest even w/o the insulating sleeve. It would be huge to have them nest to conserve all that space in your pack. And I would not trust the lid to stay on if attached to the outside of your pack. Lid fits great to drink from but not comfortable to have it strapped on outside of pack. Otherwise a great item for the price.

I had to put a rubber band around the cup to keep the insulation from being too easy to come off. Other than that. Great mug!

Light weight and keep a lot of fluids. However it does not fit in car cup holders. Perfect for camping.

This goes great with my GSI brand cook pot which is 20oz size, and fits nicely with the sleeve. I am focusing on that for my review because thats why I bought this is that it ls light weight, and can nest.

Worked well, kept things warm. Only downside is the fabric insulation outer can get wet

Finally, a cup worthy of my backpacking coffee! Ive tried all of the over-priced titanium models. They either burn your lips and dont keep it warm, or cant be used to heat water. The GSI Mug holds about 17 ounces of water (16 oz fits without over-filling), weighs 3.8 oz, and keeps my coffee really warm. I used a sharpie to mark 1/2 cup increments for measuring which should have been done by the manufacturer, but no big deal. I put boiling water into the cup, which was at room temperature, and after about 10 minutes, the water was still measuring 190F. Most importantly, unlike some cups, there is no plastic flavor.

Great cup for camping. Cup comes out and you can use it to measure liquids. Stays hot for a long time.

Love the measuring markings on inside cup both in ounces, cups, and metric conversion

Beautiful material workmanship. The cozy comes off and the cup has graduations for liquid measurement. Very light weight and perfect for backpacking, or anytime.
