Mystery Ranch Size Chart The Ravinee will serve you well on those light, overnight trips when you want your puffy jacket, camera and basic camp kit. The framing strikes the ideal balance between lightweight yet beefy; it's amply supportive for the medium-size loads this 50-liter pack was designed to transport. Featuring 3-zip access, loading and retrieving items from the pack is quick and easy. The Adventure Frame is lightweight and yet beefy enough to support larger loads. The removable, double-wrap, re-direct waist belt integrates directly with the frame for a dynamic, efficient carry. Features: - Lightweight, robust Adventure frame - The mainframe is comprised of two vertical composite rods, an upper horizontal composite bar, and an aluminum lumbar stay. The composite cross stay keeps the vertical rods properly aligned and allows them to pivot and flex for a dynamic, stable carry. There are two upper portions and one lower of an HDPE frame sheet for added structure. - Mainframe transfers the weight of the load into the wings which relay the weight and equalizes the contact around and into the belt. The waist belt cants and conforms over the hips to effectively transfer and distribute the weight and eliminate slippage down over the hips. - Futura Yoke easily macro adjusts to the torso length allowing the proper amount of stand-off between the back and frame. - Classic 3-ZIP design for easy, rapid access to the interior. - Removable, double-wrap, Redirect waist belt system that secures in a natural, forward pull direction that requires less effort to tighten. - Two vertical "torpedo" pockets for external access - Water bottle pockets keep hydration handy - Zippered lid pocket for quick access items - Hydration reservoir compatible - Adjustable ice axe loops for trekking poles or ice tools - Double-layered bottom for long-haul durability - 210 Robic honeycomb/420 Robic nylon fabrics - YKK(R) zippers - Dimensions: 34"x17"x12" - Weight: 4.7lbs - Volume: 3051 cu in / 50L
