STOJO On-The-Go Biggie Collapsible Coffee Cup with Lid - 16oz / 473ml - Reusable & Foldable Silicone Travel Mug - Portable, Pocket Size - Dishwasher Safe - Carbon

Bought these to take on holiday and they worked very well. We only used them for cold drinks & water but they fold away and are light so great for taking out for the day. The screw top with closable drinking hole was useful. Once the initial taste has gone they didn’t affect the taste of the drink & were a good size.

Was a bit dubious after some of the reviews, but went ahead and bought. Seems really good construction. Takes a couple of goes to efficiently open/ collapse, but it is pretty easy. The hard plastic heatproof ring that goes around the middle can be turned around and stowed in the bottom of the folded cup, so does not take up extra space. Easy to clean and does not add any taste to the coffee. I use this frequently - a good buy. EDIT: After 5 1/2 years it has given up the ghost. It sprung a leak this morning and I got sprayed with hot coffee. I did order a spare recently, so hopefully I'll get another 5 years out of that. But not sure I will buy again - shame as it was just what I needed :(

A surprisingly decent mug that will collapse to a fairly small size whilst still being sufficiently robust to be usable for hot drinks. I'm not sure how watertight the lid is, but it will prevent minor spillages and keep a drink warm for longer.

I've had my eye on the Stojo series for a while and decided to treat myself before a trip. I already have a tumbler for my coffee on the go, but the Stojo is fantastic because it collapses after use, fitting easily into my smaller bags without taking up space. It expands to a good 16oz size when needed, is easy to wash, looks cute, and is functional. The price is reasonable given the material.

It’s a nice cup but it leaks fairly often. Something to do with the seal where all the individual pieces fit together. The cap doesn’t leak though so if you align the neck to the body closely and screw the lid on nice and tight (while still being able to unscrew it again, which is a difficult balance to strike) you’ll be ok most of the time, but it’s easy to get unlucky! I had a smaller version before (same problem with both, I just forgot why I stopped using the first one!) but on the whole it’s the best cup I’ve found as cleaning is super easy (either by hand or washing machine), keeps the drinks pretty warm and doesn’t leak large amounts. Neither of them have had any issues aside from the leaking, collapsing it down doesn’t cause any damage and dishwashing doesn’t cause any brittleness it seems

Great travel mug. Its a great (large) size. It folds down easily and isn't hot to the touch which can happen with silicone. Only thing is it folds down to be quite bulky - its fine in a bag but not easy to put in a pocket, but this hasn't really been a problem

These collapsible mugs have been very useful for taking on holidays. We can carry tea and coffee from machine to chair without the risk of spilling and they fold away to take up very little room in a suitcase. They seem quite robust and should last well.

Great portability, compact, sturdy. The issue is the smell! Tested it with water straight out the pack and 10 minutes later the water took in the most disgusting, chemically flavour. Used soap and boiling water to clean but water would then take on a soapy taste combined with the chemical. Used baking soda as a paste and scrubbed it on and left over night for THREE DAYS in a row and decided I'll risk it even though it still wasn't smelling great. Regret, got a coffee in it while I was out and had to pour it out as the taste of the cup rapidly leached into my drink. Used baking soda once again. What FINALLY made the cup usable was putting it in the oven. Did 130C for 30 mins which did absolutely nothing. Later tried 150C (I wouldn't suggest going higher) for a whole 1 1/2 hours. It really did take that long and even then still had a faint odour. Added baking soda paste again overnight and finally, the smell and taste were gone! Of course, like silicone does, it quickly taking in the flavour of the thing inside. I mainly use this for decanting my tea into from my flask which is too hot to drink from. Tea doesn't leave much of a smell behind but once I have coffee in there I need to give it a deep clean before having tea again. It's a bit high maintenance for a simple travel mug bur I imagine any collapsible ones will have a similar issue. Also wish there was a greater colour variety like on the official website. The grey one is kind of ugly :(

I love love love this cup. I wanted a reusable coffee mug that could fit in my backpack and this does the trick. It fold up really easily and it’s completely leak proof if you plug the hole with the rubber cover on the cup. The plastic sleeve that comes with it makes the cup more sturdy when it’s expanded and allows you to have hot liquids in it as well. I definitely recommend this cup to anyone looking for a easy to carry reusable mug!

La taza es magnífica en cuanto a diseño pero este tamaño es algo obtuso, demasiado grande para llevarlo en el bolso

Arrived much earlier than expected! Loved the quality upon arrival too!

this is my second stojo cup. my first is the sage 12oz which I use daily for coffee, tea, or foods like yogurt. the aquamarine color looked so cute especially with the perfectly matching straw. the larger 16oz is perfect for making instant noodles on the go as well. you do have to make sure the lid and rim is super wiped dry or else it will leak when sealed. it works be cool if it could collapse even flatter, but I still enjoy these Stojo products!!

Nice idea, well executed. I like that it comes with a straw and can be used for hot and cold drinks.
