humangearGoCup | Compact Storage | On the Go Cup | BPA-free, PC-free, Phthalate-Free, Large (8 fl.oz/237ml), Blue

I use the small version in my small purse and the big version in my bigger purses. Its sturdy, the medicine compartment stays closed, and the size is useful and convenient! It also doesn't taste funny when you drink water out of it.

I admit it: I have the potential to be a veritable germophobe. And when I recently saw a report on TV with regards to the cleanliness (or lack thereof) of glasses in hotel rooms and hotel bathrooms, I decided on the spot that on my next trip I needed to bring my own personal and clean(!) cup.From a few years ago I remembered these collapsible cups made of plastic or stainless steel (such as the Colonel Conk Sunstar Model 507 Collapsible Cup) and initially wanted to get one of those, but then came across this lightweight silicone solution from humangear and decided to buy it instead. Having just returned from my first trip with this cup, I am happy to report that it worked very well for its intended purpose.The reason I am not giving it 5 stars is strictly because the walls of the cup are a tad too flexible for my liking. This makes it a bit tedious to handle when the cup is filled with liquid as it squeezes considerably out of shape simply when holding it. I quickly learned to not fill the cup too much because it then spills very easily.However, this is a small price to pay for peace of mind. The fact that it can be collapsed quickly and then stored away somewhere (and yes - out of sight from hotel maids and potentially unsafe cleaning methods) is great, and since it is very lightweight it is perfect for the road. I recommend it to all my fellow closet-germophobes :-)

This is the perfect size for my use. I need a travel cup to take to work, so I can mix my Calms magnesium powder with water. The sizing is very confusing, however. The name of the item is Large GoCup, but the drop down choice is only for Medium or Small. So, I picked the Medium. If you fill it almost to the rim, it holds 3/4 cup. There are markings on the side of the cup, but I did not find them to be accurate. It is a rubbery material. You take off the top, which has a small inner container for pills, which really isn't big enough for my use. Then you pull up the collapsible cup. It stays up! Once you pour your liquid in, it is better to lift it up with both hands. Once I have it up, I am able to hold it with one hand to drink. Then, you push it back down to collapse it. It appears to be very sturdy, and looks like it will last a long time. It's one more thing I need to wash by hand, but I don't mind, since I rinse it out before collapsing. Just what I needed!

This collapsible cup is so easy to travel with. I actually use it to soak my orthodontic retainers while away traveling and it is perfect for this. It also has a pill storage cup attached to the lid. So glad I found this.

This is the ideal travel cup. It is durable, easy to store and expand for use. It holds a reasonable amount of liquid and can be used to store some meds. It is also an excellent bugout bag item. I am very pleased with this quality made and cost effective product, and highly recommend it.

I had a travel cup many years ago but it was made from hard plastic and it did break apart over time. I used it when my children were young for those unexpected times they needed a drink and the only thing available was a water fountain that they could not reach. I like this cup because it's a nice size (8 oz). It's easy to open and close. The only negative about it is that it's made of a soft material (it's a popular material but the name of it slips my mind, sorry) that makes you feel as though it will not hold the liquid without spilling but it does do the job and I'm glad to report, no spills. I definitely would recommend it and I'm considering purchasing the smaller cup (4 oz) as well.i

This Humangear collapsible cup is so handy and compact. It's made well and cleverly designed. Although you might question its sturdiness at first, I'll reassure you I had no problems with it tipping over or collapsing while in use....of course the primary purpose for this product was for quick teeth brushing at the airport.....I can't say much otherwise.

I think a regular "cheaper" plastic pill cup would work just as well.

Great product for travelling.

Good quality, very handy.
