Wearable Hydration Sleeve | 12oz Water/Sports Drink Capacity | Leak Proof, Food-Grade | Adjustable, Breathable | Running, Hiking, Cycling, Camping | Black

Highly convenient and comfortable to wear. Not a whole lot of water storage, but if you're not wanting to get cramps you should only be sipping on it rather than gulping it down when running. Which takes discipline!

I initially bought this product on Kickstarter when it first came out and I loved it. I prefer it to camelbacks, canteens, or water bottles for hiking or running because it's much easier to carry around, it's lightweight, and the material is very breathable. The only downside is the tan lines you get from it, but it doesn't stop me from using it or from buying a replacement.

Everything bugs me when I run, except this! I have to wrestle it onto my arm, but other than that, it stays put, doesn't bother me as I run, and gives me just that little "Wet Your Whistle" bit of water, to get me home alive under this Arizona sun. Granted, this is just a "convenience" water supply for when I ride my mountain bike to keep me from having stop to access my cage bottles when I don't feel like it. A quick way to kill the Dry Throat syndrome, until I can stop and properly hydrate. I wouldn't advise relying on this for your sole hydration, as it only holds a small amount and goes by FAST, but it's an awesome add-on!

I ordered the wetsleeve for the purpose of using while running. The product was delivered a day earlier than scheduled. I have tried hand held water bottles and also belt-type solutions, neither of which were great for me. My hands get tired of gripping the bottles, and I don’t like the feeling or sound of water sloshing around on the belt.This seemed like a good solution, and I’m so glad I ordered it!! It’s a win for me. I like that it has the feeling of just being a part of your body, versus the extra gear feeling. I can’t explain it, but it feels more natural. Mine does not leak, the liquid stays cool, and I’ve not had any issues with the sleeve. I’m about 5’6” and ordered the small (black) based on arm measurement. I will be interested to see how it does as the weather heats up this summer and would have ordered a pastel color if that option were available.Great item and I’m giving it 5 stars!Update 9/2018 - After using the wetsleeve regularly over the summer, it developed a hole around the plastic fold and no longer holds liquid. Each time you fill it up you have to fold the inside plastic portion in order to velcro it closed. It didn't last as long as I expected. Additionally, I tried to contact the company, twice by phone, once by email and they did not answer the phone, nor return the message left via voice mail, nor reply to my email. I just wanted to see if there was an option to purchase the inside part since the outer sleeve is fine. It's hard to get behind a product that lacks customer support/service.

I use the product for my training runs and races. I got the small to be tight fitting. Might be tight at the beginning but you forget about it very quickly. It is a great alternative for the bottle in hand which I don't like. In summer days I freeze the liquid and insert it to the sleeve before the run. Depending on your hydration needs and the season this should be sufficient in runs up to 90 minutes in warm weather.

I ordered a medium using the guidelines and it was too tight after I filled up the bladder full of water.It was cutting of my arm circulation. It started to leave 50 bumps on my arm from shaped like the inner lining of the sleeve.I had to remove it after 10 minutes.I think I need a larger size.

Too hot and uncomfortable for walking. I took the water bottle part out and carry it in my pocket. It works well and tastes fine.

This is the best running hydration method yet - I have tried belts, camelbaks, belts, etc. The Wetsleeve fits comfortably on my arm, the water does not splash around, and I hardly notice it is there. It is easy to drink from. The only limitation is that it only holds 12 ounces of water, which is not enough for longer distances. For this reason, I ordered a second Wetsleeve, one for each arm. If you dislike wearing hydration belts or hand-held water bottles, I highly recommend the Wetsleeve.
