There’s hardly a rigid element on the Advanced Skin 5Set, right down to the squishy collapsible flasks in the front pockets. Soft trim, stretchy side panels, a form-hugging fit and airy mesh on the straps and back collude to make this a supremely comfortable vest. Similarly, the elastic chest straps do not feel constrictive—though, when pulled tight, they loosen almost immediately, making it hard to cinch down the fit. The 5Set is compatible with a two-liter bladder, and a roomy back pocket, accessible from either side, allows for quick stashing during runs.
