Mouth piece falls off easily when taking in and out of running tights. I found that the bottle works without it so I’ll be tossing the mouthpiece as it is too much of an inconvenience

Wow, super impressed how well the smaller bottle worked with the compression tights. Can’t even tell I’m carrying a bottle unless I think about it… no bounce, no sloshing, totally comfortable. I’ll use this 150ml bottle for my MLR’s with a carb mix for fueling. Haven’t tried the large bottle yet, plan to use that one when the full Florida 🥵 🔥 kicks in

This bottle is perfect! It took me a moment to figure out how to get the water out. Perfect for short walks/runs in the hot desert! Fits perfectly in my fanny pack. Super durable, I drop everything and this has survived several times, the durability is important, has a bit of a stretch. Had a weird smell when I opened it, but washed it with warm soapy water and the smell is gone. Easy to clean with a bottle cleaner and straw cleaners for the mouth piece. Light weight, I didn’t need it for hydrating, more for my mouth getting dry. Price is excellent, not a huge marathoner or anything so just needed something small.

I love the size of this water bottle. It is perfect for skiing water to get hydrated but not too bulky to have in your belt. It is super easy to use, I love the feel of the bottle, and the twist cap is really easy to use while running. It’s super durable and has held up really well through many many washes. I haven’t noticed any plastic taste either which is always a huge win!

I bought both the 6oz and 11oz and found that when topped off, the 11oz is way too heavy for my Flip Belt to handle. It kept sliding down my butt and I would constantly need to readjust the belt every few minutes, and eventually had to pour out more than half the water to make the belt stay.The Flip Belt handles the 6oz a lot better (when full) and I highly recommend getting the it instead of 11oz.Wish you all the best in health and in life!

I purchased two of the 6oz bottles, and so far they are great! They are well sealed and do not leak, even if carried sideways or upside down. The small form factor and flat shape make them easy to carry in a pocket or in the flipbelt. They stay in place well, and when I carry them in the flipbelt I forget they are there.

I am marathon training and there are water fountains about every 6-8 miles on my long training run course. This fit in the back pocket of my lululemon running tights perfectly and keeps my hydrated in between water fountains where I can drink and refill. No leaking whatsoever, just make sure the lid is turned to the closed position (aligning the grey tabs with the blue dots is “open”). No pushing in and out with teeth required as mentioned in many of the reviews. Perhaps they changed the lid design?

Very hary to get into flip belt slot

I bought the 11oz. bottle along with a belt and hat. Love the belt and hat. First time I used the bottle I noticed that the cap leaked on the drive to my run. And then it fell out of the belt less than 30 seconds into the run and I know that it was positioned as expected. I tried to hold it in my hand during the run and it just kept leaking over my hand. I got so fed up after a while that o tossed it into a garbage can less than a mile into the run so that I didn’t have to deal with it any longer.

As a water bottle it’s average. I like the nozzle design. Unfortunately, it was too heavy for the belt it’s supposed to work with when full and kept trying to fall out. I ended up carrying it for 6 miles in my hand.

Rubber on the top of the bottle fell of during my first race. Unable to drink from it without the rubber

I love the shape, and the size works well for me. My first concern is whether the cap actually gets cleaned when I wash it. The biggest downside is that when I twist the cap to open it, the entire lid loosens. It takes two hands to open it without loosening the whole cap, which is a problem when I’m using hiking poles. Will use the one I have, but won't buy another one.

Not the easiest to use while running

I love this running water bottle. It fits great with my running belt. It is comfy while wearing and easy to use.

Works well and doesn’t bounce or move in the belt

Looks awful cheap.

Good

I bought 2 Arc Water bottles and they both leak. Both caps are missing an o-ring/gasket on the inside, so this is either incredibly bad QA or an obviously flawed design. I tried emailing Flipbelt to request o-rings, and got an automated, AI-written response that told me to file a warranty claim. The link to the warranty page in the response went to an inaccessible webpage, so that unhelpful. I don't recommend these water bottles, unless you like water dripping down your shorts as you run.

Wonderful! This bottle has the perfect size for races running!

I was very satisfied with the design of this bottle to fit in my belt so comfortably.It is easy to slide in and out easy to clean and the water taste like I’m drinking from a normal water bottle. I was very happy with this purchase.

Lightweight, holds a good amt of water. My Husand uses two at a time in His belt (swaps them during runs) My Husand uses them for his marathon training/ log runs. He’s used them for years and only got more when he ran over one when he left it on the hood of his car on accident! Ha!

Works as intended, and it is very convenient to carry using the FlipBelt. Excellent accessory.

I’ve been using the FlipBelt Arc Water Bottle during my runs, and it has been a total game-changer. The curved design fits seamlessly into my FlipBelt without bouncing or feeling bulky, and it’s surprisingly comfortable even on longer runs. The size is just right for staying hydrated without weighing me down.The bottle is easy to squeeze, and the nozzle makes quick sips possible without breaking stride. Cleaning is simple, and the quality feels durable enough to last through lots of miles. I also love that I can carry one or two depending on my distance.If you already use a FlipBelt, this water bottle is a must-have accessory. It’s convenient, comfortable, and solves the problem of carrying water without extra straps or packs. Highly recommend!

This a great water bottle. I don’t have a FlipBelt but I ran across this water bottle when I was searching for a water bottle to use when walking. I usually walk in denim shorts. This water bottle is perfect! I fill it up and flip it into my pocket. The curve of the bottle makes it fit nicely against my body. I was worried about it falling out of my pocket, but it doesn’t. I’m not a runner so I can’t speak as to how well it would work for runners who skip it into a pocket.

I love my FlipBelt and ordered this so I won’t have to carry water during long runs. Tried it for the first time today and within 2 minutes of running it had fallen out of the belt and onto the ground and cracked! I had it positioned between the two openings in the back as shown in the product images. Now it leaks and I can’t use it. Waste of money!

The bottles just leak. Horrible compared to the old model. The wider mouth for electrolytes is nice but leaking is unacceptable.
