Here's what customers have to say
The running vest offers ample storage, breathable design, and secure fit that prevents bouncing, making it well-suited for long-distance runs and ultramarathons. However, some users have reported issues with recent design changes, such as the removal of certain pockets and reduction in size of the rear pocket. Concerns have also been raised about durability, with problems like fraying fabric and issues with the hydration system. While the majority of reviewers still consider it a top-quality running vest, especially for trail running and ultramarathons, a few found the fit to be too tight or restrictive.

Worked great for my 50 mile ultramarathon
I bought the ADV Skin 12 for my first 50 mile ultramarathon, and it worked great. It was comfortable throughout the race, there was minimal jostling, and no chaffing.

new version, lost features…
this new version no longer has the top stuff pocket or the upper front shoulder pockets. Bummer to lose those two nice features. Front now maybe replaced with straw stow sleeve. Don’t get why they downgraded the former flawless design…

Not comparable to original ADV SKIN 12
If you are like me and thought you would get the same original version of your ADV SKIN 12 you will not. Multiple features are missing, the back pocket is hard to get into with a lot less room. There is no longer a separate space to put your bladder, it rest right on the mesh now. The additional pocket to store things at the top of the back of the pack is also missing which was a huge benefit in long endurance runs. The side zipper pockets are also much smaller. I regret this purchase. If this many changes were to be made, a different model should have been released and not use the same name as the older one.

Has a lot of storage room for snacks. Feels very light and doesn’t bounce.

ADV SKIN 12 review
Overall is a great product, but I am having some quality issues with it since the screen on one of the pockets already has a hole in it and I have baby this bag since I got a few weeks back.

Still the best running vest
Very comfortable and secure with no bounce. Simple to use and intuitive. Build quality is excellent and has held up to years of hard use.

ADV SKIN 12
Très décu par la disparation de la poche en haut du dos, qui permettait un accès facile pour ranger une veste. la poche tunnel en bas de dos censée la remplacer est beaucoup moins facile d'accès et donc d'utilisation. ce sac est parfait à part cela, mais cette poche est vraiment un moins. et d'autant plus incompréhensible qu'elle réapparaît sur la version SLab.

Very comfortable and great sizing
I've used this product for about a year now and have nothing but good reviews so far! Plenty of storage in the very accessible front pockets. Even though I rarely fill the 12L, it's a nice option to have and doesn't feel too large when I don't pack it. Overall would recommend this pack!
