Big Agnes - Lost Ranger

Freshly updated for 2015, the Big Agnes Lost Ranger 15 offers warmth, compressibility and big comfort. This Big Agnes System bag is filled with with DownTek™ water repellent down - perfect for the weight-conscious backpacker who wants a little more elbow room and has admitted that even the weatherman can’t know it all. Utilizing their full pad sleeve design, you can slip any 20” rectangular pad into your bag to stay warm and supported all night long.
This bag uses a full pad sleeve design: the bottom of the bag is non-insulated to save space and weight. It requires a 20-inch wide pad underneath (sold separately) for comfy, warm insulation.
What's in a Name?
Lost Ranger Peak, a few miles south of Big Agnes Mountain, is perched above one of the most beautiful basins in Colorado. In the dead of winter, it could possibly be one of the most inhospitable spots anywhere. The jet stream is most comfortable when resting on top of this flat-topped peak; even on huge snow years, the summit of Lost Ranger is scoured to the frozen ground. Legend holds that rangers from North Park and Hahns Peak arranged a meeting on the peak and one fellow never showed thanks to a late September snow storm. It’s a topic of debate as to which ranger lost his way, the answer you get depends on which local ranger station you ask.

- Insotect Flow™ Construction: an insulation system that delivers uniform heat distribution and natural body contouring through its revolutionary baffle design. Flow construction eliminates lateral and vertical down shifting by using vertical chambers with Flow Gates to regulate fill positioning and density. With continuous vertical Flow chambers in place of traditional side seams, Flow bags eliminate potential cold spots which can occur with side seams. Vertical baffles now flow with your body for more rapid and uniform body heat distribution.
