Review on 🏃 Nathan Men's Hydration Pack & Running Vest – VaporAir 7L Capacity with 2.0 L Water Bladder, Hydration Backpack (Black/Charcoal/Nuclear Yellow, XS-M) by Christopher Pfaffe

This is a hydration vest that got a lot of reviews and I really wanted it to work. For some reason Nathan only offers two sizes, I hit right in the middle which is 38 inches. The little one was too small, the big one couldn't be made small enough not to bounce. WHY Nathan doesn't at least partially overlap size ranges, or better yet, doesn't offer more sizes, remains a mystery. For example, the very popular Salamon Adv 12 vest comes in 3 sizes and their latest model offers 5 sizes. I can fit in medium or large. I don't need 12 liters of storage, otherwise I would take it. I will look for a smaller capacity vest from them. If Nathan had suggested a better size I would have kept one of the vests (I ordered both from Revain hoping one would fit) - instead I'm sending both back. Very disappointed.
