Great little pack!

This pack is comfortable and fits good. I love the side adjustments so you can get that tight fit around your ribcage. There is only one gripe that took away that 5th star. I would LOVE if the chest adjustments went up further so that I could secure them OVER my larger bust. The top one only goes right to the middle of my boob. Not the biggest issue but if you have a larger bust, take that into consideration. Overall, great little pack!

Not good for distance trail running

I've used it once or twice and have initial impressions

Do not like the water bladder or the reservoir valve. The water sloshes around when you run because you can't get the air out when filling it. Terrible design. Also, the reservoir valve is poorly design making the water flow too low. This is NOT a good hydration pack for the distant trail runner.

My Soulmate Pack

I had a competitor's hydration pack and it rubbed me the wrong way in more ways than one. After enduring quite a few painful runs, I took the chance on this gorgeous little pack after the recommendation of a friend. I was skeptical because all packs are the same and I just knew I would end up battered and bruised again. Nay,nay. I fell in love with this pack after run 1. I used for a half marathon and every long run since I received this beauty. Not only does it just mold to my body and basically disappears on me mentally when I wear it, love that btw, but it's such a cute colorway. If this wears out then I will 100% buy another one.

Practical and great features!

[This review was collected as part of a promotion.] Cute, sleek and practical! I love my vest. Thus far, I've only used it for hikes, so I haven't been able to run with it yet. It was just a day hike so the pack itself was great! I had enough water for the hike, and the pack was able to hold extra snacks and my gloves. My only issue was that it seemed to be leaking as we were hiking. I couldn't figure out where the water was leaking from, as there weren't any holes and it was a gradual leak in the sense that I wasn't constantly losing water, but it was annoying.

Great pack.... water flow is too low for my liking

This is a great hydration vest, with one exception: the water flow is low in comparison to other hydration packs. Otherwise, the vest is high quality and great looking.

Fun lime-yellow color!

[This review was collected as part of a promotion.] Great vest. The bladder stays in place well. The vest seems to run a little small but I love the lime-yellow color. I love the outside zipper pocket and space inside, it fits everything I need.

So far to good!

Went on my first run with the vest. So far so good. Only ran 3 miles. Bladder at the top held up, no rips.

I want it in every color!

[This review was collected as part of a promotion.] My most favorite pack is this one! I have tried so many brands, even...but nothing beats the adjustability of this one. I have the 1.0 and had to get the 2.0 as well! I love that there are adjustable straps in the front AND on the sides!!! It allows for the perfect fit. And, as someone with a larger chest, I love that, because of the aforementioned adjustability, I can position the main shoulder straps over my chest in a way that it adds an extra layer of "non bounce" protection! haha. I realize not everyone may care about that, but regardless, this pack is light, comfortable and holds more than enough water and has amply storage space for other items as well! Highly recommend.
