CamelBak Arete 18 -
If you're the type of the person who calculates combined weight and cuts off tags to save half an ounce―OK, that's a bit extreme―then CamelBak's Arete 18 Hydration Backpack may be the solution for you. Tipping the scale at a whopping ten ounces, this slim pack will fit in perfectly with your lightweight obsession. Use it as a reservoir sleeve for CamelBak's already lightweight two-liter Antidote reservoir or stuff in your own summit essentials. Either way, the Arete's DWR and PU coated 70D diamond box nylon construction will protect your gear from wind and rain without weighing you down. In fact, when the 975 cubic inches of compartment space is largely unoccupied, tighten down the two compression straps for a denser and less-bulky pack. From extra water to sunglasses and snacks, the Arete may be light, but its sure got your back when it comes to carrying trail essentials. 

Season after season, CamelBak's super scientists have been hard at work refining and perfecting the Antidote reservoir, the industry's most popular solution to hydration. At the turn of a cap (a quarter turn to be exact), you can open or close the reservoir, refilling and securing it again in seconds. Center baffling and a sleek design prevent your water from jostling about inside your pack while running, hiking, or hitting the park. When not off exploring the world, simply disconnect the tube using the Quick Link System and hang up the Antidote for proper drying or storage. Since last year, CamelBak's go-to reservoir system has actually lost some weight, reducing bulk in the fill port and offering you that much more convenience.


  • Wide-mouth port cuts weight and makes it easy to fill and clean the reservoir; quick-snap cap tightens in just a quarter turn
  • Quick Link™ system lets you effortlessly add accessories such as a Fresh™ filter, insulated tube, tube director or flow meter (accessories sold separately)

  • Turn the Arete 18 inside out and it transforms into a reservoir sleeve that can be placed inside a larger pack for multiday adventures

The Arete 18 Pack from Camelbak has plenty of space for your gear and liquid, so you can focus on the journey before you without worrying about what you may have forgotten. The 2L reservoir keeps you hydrated on your trip, while the NV back panel's upper pods articulate for excellent comfort and ventilation, keeping you at your best from beginning to end. For added versatility, the Arete 18 can actually be turned inside out and act as a hydration reservoir for larger packs. Talk about convenient!

The Arete 18 from CamelBak is a unique dual-use hydration pack. It is big enough to carry your 2 liter hydration bladder and enough gear for a daylong hike, or it can be turned inside out and used as a bladder sleeve that will slip into your larger pack for longer excursions.


Serving double duty as a hydration daypack or as a reservoir sleeve in a larger pack, the CamelBak Arete 18 Hydration Pack hauls 70 fl. oz. of water, plus your essentials for a day in the wilderness.
