When it comes to all-around performance in a large hydration pack, the Osprey Skarab 18 has you covered. With daypack sized capacity, dedicated hydration bladder sleeve, multiple compartments, included Osprey Hydraulics 2.5-liter bladder, drinking tube, and bite valve, the Skarab may turn into your go-to pack of choice. The Skarab is for anyone looking for an all-purpose hydration pack for general use hiking, scrambling, travel, and even some light biking.
The Skarab beats out its most comparable competition, the CamelBak Cloud Walker 18, which features a better drinking system but falls behind the Osprey model in all other performance metrics while costing a bit more. This is our favorite versatile pack for multisport days in the outdoors, earning our Top Pick for Large Capacity of all the hydration packs reviewed.
