love my Fairshare

This mug rocks.

Those that have issues with bulkiness need to get creative. You can easily minimize the space this thing takes up by packing it full of gear/food. I use this on search and rescue missions where hot meals are a necessity but we aren't on our own time. I pack a mountain house meal inside the mug along with a spoon. Then when I can catch a quick break I fill with boiling water, seal it up, clip it on my pack and it cooks while I work with no spilling. Then I can eat and close it back up as time allows.

its also great for mixing larger batches of coffee or cocoa to share with a friend, I hate mixing up three separate 8 ounce servings of coffee - this is a big time-saver.

I find that this mug needs a good rinse though, especially around the threads where the lid screws on - otherwise it tends to hold a little flavor from the previous meal.

I love being able to set this thing down on the ground without it tipping over, and closing the lid and hanging it from the tent with a carabiner is also really convenient when you lack space (just make sure that lid is sealed).

Of course there are smaller/lighter options for a drinking cup, but this thing is unbeatable as a camp kitchen and provides a variety of applications and time-saving uses.

I didn't know there were multiple colors but I will certainly pick up a few more of them if I can find them!

Awesome mug

Fantastic item. I wasn't looking for this in particular when I was at REI but as I passed it on a shelf it caught my attention. I just kind of thought it was one of the coolest concepts I had seen in awhile. Very tough construction that is like that of a nalgene bottle in many ways. Lid seals great and unscrews easily. I got mine in orange because I thought it looked awesome. I use it for soup, ramen noodles, and coffee out on the trail. I occasionally use it at home for coffee as well. On days when I ride my bike to work I will fill it with coffee and throw it my pack to drink at work. Love this thing. I am sure there might be more lightweight or compact solutions for a mug out there, but I cannot get over the coolness of this thing and instantly fell in love with it. Also it is gigantic and can hold as much liquid as a 32oz nalgene. Since it is not insulated you can warm your hands by holding onto it when it's cold.

This is not a mug. And you'll love it.

With its size 32 fl oz. to the brim, this is no pushover mug; in fact it's a bowl.

I've only used it on weekend over night camping trips and its seam to get its job done very well.

I will give it a go on higher altitude, taking it to the Bugaboos in British Columbia in March-April. I am not at all turned off by the fact that its not insulated (since the review above lists that as a con), insulated metal bowls/mugs tend to get cold much faster then these non-insulated polywhatever ones in my experience, they also can burn your hand, the handle on the Fairshare is thus a big plus.

The only thing I don't like about it is the amount of space it takes in my bag (due to the handle mostly). However let's be fair, I've been camping with a white gas stove, and I haven't yet checked if a butane/propane canister will fit in the mug, if it does then space may be justified too.

I've got an orange one and love it!

Makes backpacking cooking simple. Bring a 1L or 2L pot to boil water and this mug and a spoon. Its all you need. Oatmeal in the morning, boil some water and pour into the mug, tighten the lid, wait a few minutes, stir, and it's cooked perfectly. Dinner...same deal. a full mountain house meal fits in the GSI mug. Cuts down on packaging b/c it allows you to put all your mountain houses in a ziplock bag. When your done with your breakfast/dinner, heat some water up and make tea/coffee (you get a after meal drink and it cleans your mug out).

Plus when your not eating, it serves as an extra 1L nalgene for those hikes that require you to carry a little more water than normal. Plus you can make an insulated cover, greatly increases the insulation of the mug.

Pleased with mug

I purchased a "fair share" mug four years ago and have been quite pleased with it. I weigh about 200lbs and eat my "fair share" when on trips and the size worked well for me. I have used this "bowl" on overnight trips as well as a 30 day expedition on Denali. It has held up well.

Most of my meals are "hot water" meals. Put food in bowl, add water, stir, wait, eat. The lid works well to keep heat in while the meal "cooks". Have your hot drink in the bowl at the end of the meal and your bowl is clean.

The handle is bulky and some of my companions have cut theirs off. I like it for stability when holding, but it is more of a pain to pack.

A Hungry Man will justify the size

I love my Fair Share Mug. Yes, it is bulky, however there are three reasons I carry it every time.

1. It holds and cooks a 2-serving pouch meal easily - just pour in dry ingredients, cover with 2 cups water, stir, twist lid on, wait 8 minutes and eat. NO POUCH SCRAPING.

2. It holds my large (or two small) isobutane canisters inside and still allows me to close the lid - so that eliminates some of the "space-eating" worries.

3. If you flip it upside down with your headlamp inside of it you will get a groovy colored glow that my daughters think is very cool. I have green, blue, pink and purple mugs - one for each member of the whole family.

Buy one.

Perfect for Pancakes!

I bought this mug for mixing up pancakes on camping trips and its perfect. Definitely holds a fairshare! I just pour in the amount of water I need using the ounce increments on the mug and add my pre-measured batter mix. The handle is great and super comfy. The lid goes on to keep flies out between batches! Pretty easy to clean, minus the grooves for the lid. Love it - and I am sure there are many more uses to come! Lightweight, simple, versatile, even stylish, and a great addition to my csr camping gear bin!

Large, sturdy, airtight mug

Use it every day to make ramen for lunch at work. I find it contains the pressure of hot water just fine after I close the lid tight and shake it--sort of pressure cooks the ramen so it's ready to eat in about five minutes without the hassle of having to actually boil the noodles. One of my co-workers wants one, too. Good for car camping or boating, but too bulky and heavy for my style of backpacking...

My Favourite Winter Mug !!

This is a 32 oz mug folks ! It is an easy way to get fluids back into your system after a hard day in the hills . It has a screw on top , and can be filled with gear while inside your rucksack !
It is not insulated , a good thing as you can warm your cold hands while you drink !
simongb at REI on 11/11/2010

best mug out there

I tend to not agree with the too bulky crowd, packed with other lightweight items and stuffed in the corner of a pack this baby is the best. I pack my Coleman Micro butane stove, camp towel and pot holder inside. I actually wish it was bigger!!!
GSI has a winner here....good-bye sierra cup

Negative Reviews:

saw awesome got lack luster

I was looking for a container that I could put left over soup in to reheat in the microwave that wouldent leak all over the bag I brought to work. I thought I saw that AND an awesome camp mug/ bowl. What I got was neither.

The good stuff.
The shape of this thing is awesome. Something about the shape is some how deceptive, you tend to put more in it and take more out of it. On the mug bowl bottle it says some stuff about some people getting served more food with 2 and 4 measure cups instead of traditional bowls and its for real. The same amount of liquid looks full in a regular bowl and pidly in the fairshare so you tend to fill it fuller. Also I drank the liter of water the fairshare contains empty faster than any water bottle. So it aids significantly in hydration, wich I like a lot. It realy is an awesome bowl waterbottle mug tupperware hybrid. Until.....

The bad.
The lid leaks.
It doesent leak fast but it leaks. Shake it or leave it upside down and it will leak. Its deceptive at first cause you will crank it down tight turn it upside down and it will be fineno drops. But accidently turn it over on your sleeping bag or car seat and forget about it for a minute and you got leaking. This one fact then makes the fairshare suddenly loose half the capability it should have. Because the lid prevents spills but is not water tight it can no longer be used to store anything, no more waterbottle no more tupperware. You can't be mobile in any way. You have to either hold the fairshare right side up or empty it. Its too bulky to use as Just a camp bowl and its not insulated at all and has no sippy lid to aid in its being a mug so it sucks at that too. Infact the mug bowls that come with the gsi cook kits do a better job at both those tasks and only sacrafices the weird missperception of volume that the fairshare afords. Also I hear people saying the kind of plastic they are made of is microwavable, but the thing says blatant on the bottom do not microwave. And if you put a carabiner or chord through any point of the handle and hold the cup buy it the cup can only be like a fourth full and not spill so no strolling around the camp site slinging my mug around like I did with my old aladdin mug I had at outward bound.

GSI should take this one back to the drawing board.The lack of water tight seal on the lid transforms what wold be a quadruple or pentuple functiondevice into a curious oddity.
AlanValentinus at REI on 01/01/2012

Usable mug, Lacks strength.

This mug is handy because it is sealable, but I had difficulty getting the threads to catch on the seal. Often times water would leak from it when my mug was heavily shaken with the lid on.

My other issue is with the strength of the plastic handle. It isn't up to par with the rest of the mug. The handle can easily be bent, especially if you are using the holes to clip the mug onto a pack. The handle could easily be snapped, which could prove issues for carrying.
Adaptive Adventurer at REI on 06/06/2011


Sorry to report, it leaks water when shaken. Leaks water if left on its side. Lid difficult to remove if tightened. However, the lid does stay on and it allows steam to leak out/in for instant cook meals. Does Nalgene labware make something simular that works better that REI could carry?

Alright product

I mainly use this product when i go snowshoeing on winter camping trips. The cup holds the amount that it says it does but it could use a better top. When you put warm/hot water in the bowl and put the cover on and shake it, water spills out through the cracks. I am aware of the gas laws and pressure when working with hot liquids but an improved lid could easily stop water from leaking.

Depending on what you are going to use this for its a decent value but i wouldnt recommended for mixing/shaking hot beverages in it.
