Functional and Comfortable
I am 5’2″, 155 lbs, and I bought a medium. It fits well and doesn’t feels good on my back. The chest straps always go across my chest oddly. I never know whether to pull the straps more up or more down. But once I get going, I don’t really notice them. The design with a zipped pocket on the left (which I use for my phone) and an open pocket on the right for more water is nice. In the waist pockets, there is room for my phone, chapstick, pepper spray, car key, earbud case, sunscreen, and a shirt or light jacket. The cinch straps on the back are nice for strapping a hat to or storing a windbreaker.Insight to those who like tank tops: I wore a tank top once, and one of the shoulder straps totally chafed my bare shoulder. Not deeply or anything lasting, but it wasn’t comfortable and it drew energy from my running effort for sure so watch out for that.When properly sized and tightened, the pack doesn’t flop around. The water does swish around as I move, but it doesn’t bother me.

Great quality vest
After trying on the Nathan and One Direction women’s vests I ended up keeping this one- the larger size. I am 5’8”, 175 pounds, athletic build, 38D. This one didnt cut into the under arms and felt best although it is the heaviest of the three. I’ve worn it on multiple half marathons and up to 15 miles, no issues and lots of storage pockets for all your needs. I have lost some weight since originally buying it and it adjusted easily to a 15lbs change.

All around great! Even for those with large boobs
I’ve been running for over a year now as someone who would never run more than .5 mile.At first I used fanny packs or just whatever backpack I could find. BUT This one is soooo good! 10/10. I like how it sits high and doesn’t touch my hips at all. As someone with very large boobs (36DDD) I’ve had no issues with how it sits or snaps in place (I do wear a sport bra from shefit so I’m pretty secure) It isn’t heavy even with my water completely full and doesn’t rub weird. I’ve been running 10+ miles and have had no issues. Lots of easily accessible snack pockets & plenty of water for my runs. I can see this also being great when snowboarding or biking.

Close to perfect
I previously used a hydration pack for running that was designed for biking, which didn’t work out so well. This purchase was a much needed upgrade that is almost perfect. Prior to purchasing this, I did go into a store and compare the teal color to the newer version. There is no difference other than the color.Size:For comparison, I am 5’7″, 34D/36C, and 145 lbs. After trying a S, M, and L in store, I decided to purchase the M. The small was too small and the large was far too large even with the adjustable front straps.Quality:The quality of the material seems to be well made. The style of reservoir is a little different than my other hydration packs, in terms for the style and material. It does have a tight seal; I have not had any issues with it leaking. I also like that the reservoir has a snap in feature to prevent it moving around too much.Fit: The straps snap on and off making it easy to adjust the placement vertically. You can also tighten or loosen the straps to adjust and improve the fit. I’ve gone trail running in this a few times and did not have any issues with the material rubbing or chafing.Pain points:For me, there is really only one pain point. There are a lot of pockets to store your items, which is great, however, the design of the pockets need improved. There is one large pocket in the front, which has a zipper to keep your items secure. My iphone 15 pro and key fits in the pocket, although the angle is a little odd. The majority of smaller pockets do not have a zipper or anything to hold your items in place. They are made out of mesh and have an open top, which resulted in multiple items falling out while hiking (i.e., sunscreen, tissues, chapstick, etc.). 🙁 Luckily someone was behind me to pick them up along the way.I would still consider purchasing this hydration pack regardless of the pocket design, although I’d likely compare more brands/models before purchasing to make sure it can hold my contents securely.

Perfect
This is my favorite hydration vest I have ever owned. I purchased a size up to allow for room over winter layers, and it adjusts perfectly regardless of my clothing. It is perfectly comfortable even when filled to capacity, does not chaffe, and its easy to clean. There are spacious front pockets that fit two 1L flasks, a zipper pouch for your phone, key clip, and mesh side pockets for snacks and small gear. It has been extremely durable in all weather and is designed for all kinds of runs and adventures.For reference, I am 5’4, 145lb and wear a shirt size small.

Love this product. Good price
Loved this. It was cheaper here than purchasing in stores that carry this item. Lots of different straps to make different adjustments. I got a small but I think you could really get a range of sizes with each one. Have not experienced any leaking. The straps also secure it so it doesn’t bounce much. I love the teal color. True to size.

Quality hydration vest
I was on the fence between this one or a much cheaper option. I’m glad I invested in this because it’s everything I needed and more. It’s comfortable, practical and has many pockets for fueling, snacks, headphones, etc. There’s also a little whistle sewn in, which I thought was a cool feature.

Great fit, but not long lasting
I love the fit of the vest and the functionality of the vest itself, however, after only three months of use, the water bladder started to leak.

I bought a medium so that I could wear it over sweaters and maybe a jacket. I wear ‘small’ shirts and tops and found it works but it is snugger than I expected over a sweater. BUT I have not tried playing with the straps.

Comfortable with good adjustments options. No problems over 3 months of trail and street running. Good water capacity, didn’t drink it all on 20+ km runs.I like small pockets, good for gel, snack, earbuds ect..Happy with the vest.
