Gear review: Salamon hydration bag Advanced Skin S-Lab 5 set

What Salamon says: This ultra form-fitting hydration pack for intense trail running comes in two sizes for the most precise fit possible. Sensifit construction reduces abrasion, ultra breathable stretch material to comfortably and securely hold bladder and essential items in the most demanding conditions. Delivered with new PVC/BPA free bladder

Snug fit for sure.  If you're happy running with a hydration belt then you may not think this piece of kit worth the money ($150+CDN).  However, if like me, you are bouncing all over the place, then the Advanced Skin is for you.  The bag does a great job of carrying your water, a small bottle of something stronger, gels, bars, and an extra layer.  However, it is not a ruck sack, it is for carrying the bare minimum only.  I have enjoyed the freedom that this fitting bag gives, however, its lightness and breathability come at a cost - the bag is very fragile.  The front pockets both wore through, and elastic draw strings snapped.  However, Salamon is very good at exchanging damaged goods.  In summary, if you're looking for a hydration pack for racing the certainly buy this bag, but treat it gently.
