Once we arrived, they popped back into shape with no issues.🚫💧 Absolutely leak-proof – We tossed them in beach bags, backpacks, the car, and even the plane without a single drip. Huge win.🧼 Easy to clean – The silicone material rinses out easily, and it doesn’t hold onto any weird tastes or smells.🏃♀️ Great for outings – Whether we were walking to the beach, exploring town, or sitting by the pool, these were super convenient and lightweight to carry—especially with the carabiner.🖤 Stylish & durable – The black color looks sleek, and the silicone feels thick and high quality.These bottles were such a simple purchase, but honestly one of the most useful things we brought on our trip.

Good water bottle, top is not constructed well.
Very nice collapsible water bottle. My only complaint is the silver cap was not very well glued on and came off almost immediate on use. But the water bottle works well with out the silver cover on the black stopper lid.

Good collapsible bottle
Kind of flimsy and one leaked a little but it collapsed easily and did the job. We filled them after we got through security from a bottle filling station. Nice not having to spend 5 bucks for a small bottle of water.

Defective product
I was disappointed. Both bottles leaked at the seals. After the first one leaked , I retightened the top and tried it again. It still leaked. I then used the second one and it leaked also. There must be something wrong with the seals or the caps. I will not buy them again.

Plastic taste
Love the concept but I can’t get the plastic taste out. Hot water soaked and dishwasher nothing has helped 😔

I’ve tried many collapsible bottles over the years, and most have been clunky or difficult to fold back and forth. This bottle surprised me because it collapses smoothly and feels well made. The silicone material is grippy, which makes it easy to hold even when wet.The included carabiner is sturdy and convenient for clipping to a backpack or gym bag, making it perfect for travel and outdoor activities. It takes up very little space when folded down and is lightweight enough to carry all day without noticing. The wide mouth makes filling and cleaning simple, though the folds do require a bit of extra care to clean and dry fully. Overall, it’s a practical, eco-friendly choice that fits easily into my lifestyle and I’ve been very happy with how durable it feels.

I didn’t know I needed a collapsible water bottle until I started carrying a lot of camera gear and realized that every gram counts for long shoots.This is a perfect solution, since at first it takes up very little room and weighs very little when empty. Once I need a drink I’ll expand it, and hang it off my bag with the included clip. I like that the clip isn’t attached to the lid, but instead directly to the bottle – this would help prevent very messy spills if it were jostled enough.When fully extended, the bottle holds 500ml, not as much as a yeti, but a fraction of the weight and bulk. The silicon is reinforced with plastic rings in intervals, which let the bottle stay decently rigid when fully extended. You have to be a little gentler with the way you hold it since its sort of squishy, but it pays off since when you’re done drinking (water only, btw) you can collapse the bottle into about the size of an apple and put it in a bag compartment.Even when fully compacted you have the option of putting in 2-3 sips of water, so I suppose it would be good in a purse or something. The lid is nothing fancy or special, just a metal cap with a gasket. I am a little wary of the gasket because when I first got the bottle I had to manually adjust it to make sure it was evenly secured on the lid.Overall I love this little-big thing, and find it incredibly satisfying to “crush” the bottle back to a smaller size. Due to its ringed shape, the silicon naturally assists with either stretching or squishing the bottle. The colour is nice too, its not white like in the picture, but more of a very light beige? taupe? sand? Whatever, its nice and earth-toned, goes great with the chic-camera bag aesthetic.

This collapsible bottle is so useful in so many situations. The construction quality is quite good, with a nice balance between thickness of the silicone and overall weight. The collapsing function is super easy to use, and you can collapse or expand it as you go depending on how much liquid you have in there. The metal lid fits securely and without spills, and the integratee carabiner is a great feature for attaching it to backpacks, etc. This is perfect for students and others on the go, and especially good for travelling and airplanes. It’s not the cheapest water bottle out there, but the versatility is great.

I love how lightweight and compact this water bottle is. It folds down so easily and actually fits in my small purse without taking up space. The silicone feels sturdy, the lid seals well, and I have had zero leaks so far. It is also really easy to clean and perfect for the gym and daily errands. Truly one of the most practical bottles I’ve bought.The only thing is it can be a little flimsy.

I have been really happy with this collapsible bottle. It holds about 500 mL when expanded, but folds down small enough to slip into my bag without taking up space. The carabiner is super handy for clipping it to my backpack or gym bag, and it feels light but secure.The silicone feels durable, has no smell, and I like that it is BPA free. The lid seals tightly and I have had zero leaks even when it is bouncing around in my bag. Cleaning is easy too thanks to the wide opening.I have had it squished by other items in my bag and it still keeps its shape and works perfectly, so it feels built to last. In my photos, I am showing the size next to a standard 500 mL disposable water bottle so you can see how compact it gets. Overall, a great everyday and travel bottle that makes hydration simple.
