The Mariposa™ Ultralight backpack,  is absolutely loaded with size, features, pockets, and new materials.  Built on the same basic platform as previous iterations we have upgraded it for durabilitly, functionality, and feature set. 

The Mariposa™ is constructed largely of our custom 140 denier Dyneema GGridstop™ fabric for a sweet spot  blend of toughness and weight. The Mariposa™ now sports 7 exterior pockets for loads of options for organizing and accessing your gear. The Mariposa™ Ultralight is a top loader and utilizes our OTT™ (over-the-top) closure system for a simple, solid, secure closure that also includes our largest zippered top pocket.   Also a taller more padded hipbelt with integrated pockets for a plusher more comfortable ride.  Completing the harness is our comfy curved shoulder strap system with our whistle buckle sternum strap and d-ring accessory mounting system. The Mariposa™ backpack has our New "Shock Top™" shock cord top-of-the-pack lashing system for attaching your foam pad or other gear to the top of the pack.  Inside the pack you'll find an updated version of our proprietary  removable stay.   At just over a pound and a half complete, the Mariposa™ remains Ultralight to the core and is tougher and more feature rich than ever.  This 'Posa™ is slightly larger than the last and our sizing has changed slightly as well so please refer to the SPECS tab for more information.

The Mariposa™ ultralght backpack is a LARGE volume pack that is suitable for most any type of backpacking trip.  The Mariposa™ is best with loads under 30lbs but will handle up to 35 just fine.  It comes with a SitLight™ pad, removable stay, and integrated but removable shock cord lacing, 2 cord locks and mini cord clip. The belt is sold separately to allow customers to choose the size they need.
