Camelbak Lobo Hydration Pack. Weighing in at just over a pound, the LoboTM is ideal for days when the weather is clear and the trail is calling days when you want to ditch most of your gear to travel fast and light. With 3 liters of hydration capacity, it carries enough water for a substantial 2 hour ride, and the external fill means you can top off the reservoir without unpacking anything. Its zippered front pocket leaves enough room for a phone, card and keys, and its removable waist belt adds stability when you're hucking over rocks. Universal helmet hooks make it easy to carry head protection when you're not riding.Camelbak updated the Lobo with another full length pocket for your bike pump and a magnetic tube trap that stows your drinking tube in one easy click.
