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

I absolutely love this cup. In my core group there are four of us, and we all have a version of this cup. It may not keep things warm all day or cold. But it’s easy to hang onto and doesn’t spill when close properly. Don’t buy just one

The product works well enough for warm or cool liquids. However, when I put in my hot coffee, the seal doesnt stick. Its as if the heat dislodges the vacuum. This is marketed as a mug that will keep your beverages warm while hiking or traveling. Thats not the case...

I now have three of these in different colors. One fits perfectly inside my Stanley cookset, and I can store my backpacking stove a lighter, and a scrub pad inside of the cup so nothing rattles around. The inside of the cup is marked in 4oz increments up to 16oz, and the plastic removes easily from the fabric insulator for cleaning. This definitely doesnt insulate like a stainless vacuum mug, but thats not what its intended for. I can easily hold it after adding boiling water to soup mixes or drink mixes without burning my hand, and its lightweight enough to take on almost any trip. Lid fits solidly and has a flap that keeps bees or ants out if you have something sweet sitting in the cup - nice touch.

This broke in less than a week. Cracked like an egg attached to my backpack via a carabiner. Before it broke lid would pop of with any hot drink in it can not transport coffee ☕ this way. Wont buy this again. Perhaps the stainless steel version is a better choice, idk.

Loved it for our backpacking trip in the mountains. Lightweight, convenient. We liked the measurements added to the inside cup.

Love these! I have purchased 6 of these over the past two years and now own one in every color to cover each of us on trips. I use a sharpie to put measuring graduations on the removable plastic cup and use them as measuring cups when making dinner on the trail. They seal extremely well and keep my hot drinks warm a long time. You can hold boiling hot water with bare hands. They drink very well for a lidded cup. Most I have tried tend to dribble more. The cup is extremely light weight for the features so I have no problem backpacking with one. The only time this stays home on a backpacking trip is if I am solo and then I use my GSI micro soloist that serves duel purpose as a pot and a cup.

convenient lightweight plastic coffee/tea/soup cup. easy to clean, no-burn cover.

Used this as my coffee mug on a 2 week backpacking trip. Very light. Lid works pretty good. Measurement graduations are a nice feature. Neoprene sleeve does a decent job of insulating. I would recommend this as primary backpacking mug for any hiker.

light weight and easily clippable.

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.
