Crenics Collapsible Travel Cup - 2 Pack Silicone Folding Camping Cup Sport Bottle with Lids - Expandable Scald-Proof Drinking Cup - Portable Bottle with 2 Straws

Unlike other collapsible cups with carribiners on their lids, you don't have to worry that your cup will fall off somewhere down the trail and all you're left with is a lid. It screws on nice and secure. It's also much bigger than the first generation collapsible cups, holding 550ml compared to the 150ml of my first collapsible silicone cup purchased nearly 3 years ago at close to the same price.I love the sturdy middle grip. Simple yet ingenious bit of engineering. This ring of plastic in the middle helps to keep the cup's shape. You can grip this bad boy and the cup will not bend yet still manages to fold up neatly together to stay relatively compact.Now for the caveats. It bends a little too much. You will need a straw to drink efficiently with this cup. If you put your mouth on the spout and suck, the cup WILL collapse in on itself and it's a bit of a pain to adjust after each sip to keep the contents from spilling onto you. It's also a little bit of a hassle to collapse back into itself. I've had to practice it over and over to get it right and I'm still having some difficulty.All in all, it's still a great product for the trail or events like Burningman. The cap has a lid for the spout so the dirt, dust or playa doesn't get into your liquids and it's lightweight and at a great price.Recommended!

To maximize space in my camper trailer i want to replace my drink cups, searching for quality, functionality and space saver i gave a try to this set. Once i received for my surprise the seller stated one year warranty on this product, nicely packaged and includes in the set 2 collapsible cups one gray and one aqua blue, 2 stainless steel straws and 2 starw brushes. The drink cups are sturdy and thicker silicone, don't stink like other silicone cups i had before . They fold really easy, fit in my pocket or my purse no problem, this grey i been using on daily basis for coffee at work and drinks and people ask where I got this. It can be use for hot drinks or cold it work good, stable to put in a table and fit in you car cup holder. Leaks? As long you put the lid right it won't leak.Well they are so nice and well build that i purchase 2 more sets so i have all my drinks cups replaced without sacrifice space in my trailer. Highly recommend for camping or people who have RV or trailers.

Update (several uses now): I figured out the straw issue. It sits nicely wrapped in a niche in the lid so no more popping out unexpectedly, yeah! Also, wanted to add that it has very fine threads and that makes it a bit particular about getting twisted shut and it has a long set of threads so it takes a few extra turns to close. Not earth shattering or anything, but a bit tedious.First use review: I used this cup for the first time recently in a Florida theme park in July. I was specifically looking for a collapsible water bottle with a straw that I could slip up under my face mask easily. This did a great job! I drink a lot of water and didn't want to have to stop and fiddle with my mask every time I wanted to take a sip of water. I was able to fill the cup (with the straw inserted) and still carry it with my finger through the clip and not spill water on myself. The original picture had a stainless steel straw, but it came with a matching rubber straw that easily rolled up into the cup.Two notes: First, this cup did sweat when I added ice. Secondly, I almost lost the straw twice because when I opened it from a collapsed position, for refilling, the straw popped out - so you might want to be careful about that. I did get better at being sure it was rolled up carefully and not "spring loaded" (ha, ha).Overall, the cup did exactly what I need it to do - allowing me to drink easily with a face mask on.

Bought this to replace a different model of cup from a different credit that I used for about 2 years before it got lost. This version is larger, the hard PP plastic parts seem to be thicker and sturdier. Mouth piece stopper is a little difficult to get in, but I imagine it will wear in a bit. I love that this can be opened to 3 different sizes without taking off the lower ring.The top is definitely larger around than my previous one, and it just barely fits in the "waste bottle pocket" of my Targus backpack. I'm hoping that the included carabineer will keep it from getting lost...Cons: like all silicone products, it will absorb smells. Clean this immediately after use with hot water and dish soap, let it air dry, etc.

These are nice cups, but they are not too sturdy. I have to be careful not squeeze or push down too hard. These do not keep drinks hot or cold. They are strictly for convenience when I want a cup but don't want to keep buying bottled water. I can fill up at a water fountain. I tried this with hot tea. The band in the middle keeps my fingers from burning or getting too cold. Nice colors but wish there were more.

I really like the convenience and collapsibility of this cup. Can be used in the microwave if you remove the clip. A little wobbly when it's full, and difficult to screw on the lid because the silicone is thin and flexible. In order to screw the lid on tightly you have to hold the cup securely. The silicone is too pliable for this and the heavier ring around the middle (to prevent burns) moves around the cup. In spite of these shortcomings, I would buy another set. Taking them on vacation so I can have my tea in the morning and evening without going out.

Highly recommend, if you're making the effort to reduce your trash footprint or single use plastics. Yea, you have to walk inside Starbucks or your favorite coffee place instead of using the drive up, but once you begin doing so, it becomes second nature. Collapsible, so I have one attached to my BOB and another in the vehicle.
