Pockets don’t hold anything
The best fits great but the two big pockets in the front are not tight so my phone and gels fall out disappointed.

Enjoying it so far
Best meets my expectations. I wanted something light weight and unnoticeable to carry more than my pockets and belt bag allow - mission accomplished. Really provides peace of mind on my weekend long runs, and worked as desired at my mountain marathon this weekend.

S Lab Ultra vest — woah! fit
Yeah this is crazy comfortable. —compared to: I’ve run 1000s of miles in my oldest (old blue) adv skin 12. The material on inside of this vest makes the (older) adv skin’s feel like sandpaper in comparison. Fit is a snug grip in all the right places. (Slim but not wirey runner in the case). I measured chest at 39.5 or 40” = medium? Nope, the medium was definitely too small. Large was my fit, just as with adv skin12. You can’t carry a bladder with this (not supposed to anyway) but can tuck another 500ml flask in the back Minimilist, great if you don’t need to haul too much water. 1 great new development: it seems the new adv skin 12s use more of the same materials as this s lab ultra, so that may be something to check out. I only got this because of sale. Otherwise—the new adv skin is comfortable, and can carry more when needed. I’m gonna run this thing top speed in a couple sub-ultra fun races and speedy trail days. Should be a blast.

Storage options are a deal breaker
This is a very comfortable, lightweight and breathable vest. However, Salomon totally missed the point on the storage options. I cannot see how you can fit 10L of "stuff" in it, except if you only pack clothes in it. As many people mentioned, this vest is missing a pocket for a phone. For many trail runners, having a phone easily accessible in case of emergency and secured into a pocket with a zip is absolutely critical. Even in race condition, many people want they phone accessible to capture a photo, check if they didn't go off route or provide an update to their crew. In that vest, your phone has be in the front pocket, without a zip, and may fly off your pocket quite easily. There are 4 small zipped pocket, 2 on the shoulders and 2 on the side. These are barely large enough to store a set of keys and a gel or 2. You cannot keep these in the main front pockets because they will fly off as soon as you go on a bumpy trail. You will regret buying that vest as soon as you try to fit items that you actually need on a trail run in it.

Wanted to love it…
I got this vest to replace my Adv.Skin 12, which was ruining some of my running shirts. The mesh fabric, on the inside of the Adv.Skin 12, doesn’t play well with Merino Wool and a few of my LuluLemon shirts. All the shirts look like sand paper was dragged across them. The Ultra 10 solved that issue…but came with a few problems of its own. Basically…the only functional pockets, are the ones that hold the water flask. The others are hard to reach or loose fitting…allowing things to fall out. The two zippered side pockets are very hard to reach and almost impossible to close one handed. The pockets, directly above the zipped side pockets, are almost impossible to reach, as they basically sit right below your armpits. Takes some contorting to accomplish. This vest seems like it was designed for someone with a crew. A crew who will do all the packing and unpacking for you…because the only reachable pockets are the ones in front. The front pockets are nice, but sort of loose. I had a couple of gel packs fall out when I jumped a curb. And that was on flat ground. Not sure how well the pockets would hold onto gear and snacks when running on slopped trails. Also…there is no water bladder pocket, like on the Adv. Skin models. But that is a minor complaint, as I prefer carrying soft flasks on runs anyway. In my opinion, this vest is good, but overpriced. If they had used the same fabrics and went with the exact design as the Adv. Skin models, when it comes to pocket number and placement…that would’ve justified the price and then some. The Ultra is light, it’s comfortable, the included soft flasks are great…but with the lack of functionality…it’s not great. But a big step, fabric wise, in the right direction. I will continue to use the Ultra as my primary hydration vest, but when carrying gear is needed, I will switch back to my Adv. Skin 12. I just wear one of my already ruined shirts when I do that.

Love at first use
Received my vest yesterday, loaded it up and ran 22 miles with it today - it was awesome, did everything I wanted. So light weight I barely noticed it, truly like a second skin. I’ll be practicing with it every weekend as I begin my ultra journey. Also, I feel much more confident in my next rim to rim excursion at the Grand Canyon with this vest in tow - I think I can actually call my friends challenge on rim to rim to rim. Great product design guys, much appreciated!

Expectation was high, but it delivered very little
Poor pocket arrangement and no ability to use a bladder with it ultimately let this down. In writing this review, I’m comparing this product with the Adv Skin 12 which is a truly great pack and as I found out, takes some beating. In short I found the side zip pockets difficult to reach and open just standing still let alone when running and further more running on technical terrain. The shoulder zip pockets aren’t really big enough to do much with and the non zipped side pouches were really hard to get into as well and they don’t wrap around the body as the Adv Skin 12 does. The lack of being able to use a bladder is an oversight too but I was going to look beyond that but with the pockets being such an issue then this makes it an even worse choice. I’ve had a number of races where warm weather rules have come into play and requiring more than the two 500ml flasks. Obviously you can take more flasks and stuff them in the pockets but with accessibility being such a problem, this isn’t a good work around. Overall a poorly thought out vest and I for one will be sticking with the Adv Skin 12.

Great quality and comfort
On of the best running vest I have ever used. Great quality and comfortable I even forget it’s on me because of the low weight of the vest.

Fits comfortable.
I really like the fit the water bottle pouches work good. Plan to use it on 100 mile race pocket will be adequate because the age stations are about two hours apart. In a perfect world, the back pouch would have a zipper or a Velcro to hold items secure but when I stuffed my pull over rain jacket in it hasn’t fallen out
