The Osprey Skarab 18 and the Osprey Skimmer 16 are our favorite hydration packs for half-day hikes. Though Osprey designates the Skarab as a men’s pack and the Skimmer as a women’s pack ...

The reason that I give this feature 4/5 stars is because Osprey has had a bit of a problem with hydration reservoir quality… the one that came with my pack leaked and I needed to get it warrantied.
