Fits good with lots of storage. I typically wear a large for everything. That being said the large fit me but with the adjustment pulled all the way tight which left me with 10” of strap flopping around as I run. Not a big deal but an FYI none the less.

Worked fantastic for an ultra. I felt / fit very light , breathable and I really like the color. I was able to fit enough snacks in the pockets and the zippers are a MUST!!! Bottles were good and like that they weren't rigid. Definitely a great vest to use.

I bought this for my boyfriend for his half marathon. He loves it because it fits water and his phone and has space for anything else he really needs, but it’s still so lightweight and not clunky at all. Great quality, too.

Perfect for long runs and hikes. Its lightweight and even when the water bottles are full, the vest is comfortable while moving. There is no chafing on bare skin and has enough storage for keys or wallet.

I have been trying to find something cute and easy to carry my water bottle, gels, phone, keys, etc on long runs during the summer for a long time. Here's my progression: x Flipbelt: Kept riding up, had to adjust while running, very annoying. x Bike shorts with pockets: Kept getting pulled down by the weight; pockets usually small and don't have zippers. x Janji multipass: Worn over one shoulder, it was secure with the stabilizing strap, but felt unbalanced and annoying (looks cool though). On the waist like a fanny pack, bounced horribly and needed constant adjusting. x Salomon Adv Skin 5 for women: Straps to secure it at the front were confusing and annoying. Also the women's version had smaller and shallower pockets??? Why do we hate giving women pockets. Too expensive for how much I hated the design. Finally led me to this one! I'm size M (6/8) in most women's clothes and the Small vest was adjustable and fit perfect. Long straps means it should fit a wide range of sizes. Two easy straps across the chest, one zipper pocket big enough for a phone, two deep water bottle pockets, and two shallower pockets for gu and stuff. At half the price of Salomon. I LOVE it! It's comfortable to wear over just a sports bra without chafing, looks cute, doesn't bounce, zero complaints. I don't use the waterbottles these came with, instead I use the ones that are made for the flipbelt (which do annoyingly leak, but are otherwise secure in this vest even when empty). Hope it lasts!

Getting into running and got this as a hydration option during my runs! Love this vest it fits very well doesnt rub or chaff on me when running even in a tank top. Has great pockets for water and snacks! Water bottles are good and are soft sided so helps to not feel like a solid surfaced is sitting on my chest when running. When I’m running and drink from the water bottles they do move a bit when not full which can be a bit annoying at times. Usually just requires me to adjust them but it’s minor in my opinion to have to do so. Great vest. Very happy with it. Will probably take it on hiking trails come the fall as an alternative to my traditional hydration pack. Would recommend!

After a 10 mile run I can say the vest is super light and comfortable. With the hydration flasks, you obviously feel more weight but it is still very comfortable. As a big sweater, I appreciate the excellent ventilation. This is an LT version so there are less pockets than other vests. I was able to fit my Pixel 7 phone into the zippered pocket. If you can pick up further hydration along your path, this vest can easily be used for long runs up to marathon length. If hydration along your path is a problem, I probably would stick to runs up to the 12-14 mile range (obviously this depends on individual needs and weather conditions). The water flasks are great. They are easily accessible during your run and I love that you can easily get water out of them with a gentle bite. Some other flasks I've used are not as convenient. Here is why the 5th star is not being awarded: During my run, I found the vest loosening a bit several times. So, I had to adjust the strings. When the vest gets loose, the water and top of vest will start having uncomfortable movement. When the strings are adjusted properly, all is fine and secure. I read a review where someone said their flask came out while running. They have ties for the flasks so I have a hard time understanding how that happened. However, I did notice that when the bottles get emptier, they do try to bob out of the pockets. I found myself shoving them into the pocket a few times. But they never fell out and the string ties remained on the flasks. I will give it a few more runs and see if these issues persist. Maybe I just need to make small adjustments. But overall, I love the feel of the vest, I love the comfort and breathability. And visually, the vest looks pretty damn good.
