INOXTO Soft Flask,Collapsible Soft Water Bottles for Hydration Vests and Running Packs, Soft Flask Running Bottles for Hiking Cycling(250/500 ml) (2 PCS 500ML)

Great bottles! I bought the two 250ml for my Nathan Running Vest for when I don't want to carry the bladder. I have used them once on a run so far and they both fit perfectly into the front pockets, don't bounce around, don't fall out, and they do not leak! They are lightweight, very functional and exactly what I was looking for! No weird odors or taste. Excellent price for the quality!

Worked perfectly. Small enough to tuck in a running vest, perfect size if you just want a few sips of water on your run.

Works great! Great quality! The cantatas on, doesn’t leak, great purchase! Drinks like camel pack.

Very convenient, but ridiculously hard to clean. I threw away after one use because I couldn't get them clean enough/dry enough to store. I bought for a trip to Zion, they did serve their purpose for my trip. Buy i didnt feel like I could get them clean and dry enough to store for another trip.

Love these for running. Easy to fold or fit in deep pockets

I live these flasks. I’ve purchased them in a couple of sizes. They are great as long as you don’t leave electrolytes in them for 3 weeks to get moldy and gross. They fit well in all my vest pockets and also are comfy to hold. They don’t leak and the cap keeps the bite piece clean Seams are strong and don’t burst with freezing (1/2 full bottle). Great value for the price

Leak proof, easy to carry, lightweight. The only issue I have is after it's washed, it takes FOREVER to dry inside.

Good product
