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

I bought these for backpacking and they were perfect. On cup does everything. The fabric cover makes it nice to hold a hot cup of coffee in the morning with out scalding your hands. The size of the cup is perfect as well.

Ive had 2 of these cup for many years of backpacking and the have never failed me.

This is a really handy mug. Liked it so much I bought one for the roommate too. And it doubles as a measuring cup if you take it out of the neoprene sleeve.

Does its job and its lightweight for hiking

Love that it has measuring marks on the side

Lost my first one. Love everything about it from the volume to the gradations to the insulation and the handy little handle. Bought one for all my friends.

The perfect backpacking mug. Super lightweight, high quality and insulated. Its an excellent value!

My new favorite mug!

great

These cups are intended for lightweight and portable convenience. They hit that mark wonderfully. The size is perfect; the neoprene sleeve is surprisingly effective; the lid is nicely constructed. Easy to clean, stylish for what they are. Its easy to miss, but they do have measurements marked on the inside of the cup. Remove the neoprene sleeve, and viola! Be realistic. Its not double-wall, vacuum-sealed steel construction. Its not a screw-on lid with locking spout. It will not retain heat for hours. If you drop it or it builds up pressure, it will come loose. If those are your expectations, youre looking at the wrong cup. After using it for several backpacking trips, I bought 2 more to put in the camper.
