Product Insights
The Salomon Active Skin 4 Hydration Jacket is a lightweight, affordable vest designed for runs up to 50k, offering a snug fit with SensiFit and dual sternum straps to eliminate bounce without lung constriction. It includes two Hydrapak flasks with 42mm openings for easy ice and powder addition, collapsible bodies that reduce slosh, and high-flow self-sealing bite valves that stay leak-free. The vest provides front pockets for phone, nutrition, and an integrated whistle, plus rear cargo with a bladder sleeve, shock cord, and pole loops, though the rear compartment is hard to access while running. It has a breathable mesh back and minimal padding, but lacks side pockets and has less back storage than the ADV Skin, making it a streamlined choice for beginners to 50k ultras at half the price of the ADV Skin 5.

Comparison of Active Skin 4 to ADV Skin
Friends have active skin 4 and difference to adv is noticeable. Sides don't have pockets, while ADV has a pocket all around. I think there is also bit less space on the back (it has zipper).
