Lost Ranger 3N1 15F (-9C)

The most versatile sleeping bag out there

Lost Ranger Peak, a few miles south of Big Agnes Mountain, is perched above one of the most beautiful basins in Colorado. In winter, its a pretty inhospitable place and certainly not one to get lost, ranger or not. To survive in such a location youd need some pretty high-performance kit. Something like the Lost Ranger UL 3N1 sleeping bag, for example. This innovative, modular sleep system offers three bag configurations in one simple yet technical package. Consisting of inner and outer bags that can be used standalone or combined, its a versatile option for variable conditions and temperatures. The outer bag also has a unique mat cinch system to ensure it stays perfectly attached to your sleeping mat, so you wont roll off in the middle of the night. In short, if youre looking for a single solution to take camping, backpacking and everywhere in between from spring right through to autumn, youve found it in the Lost Ranger. These lightweight, down-filled bags deliver optimum comfort whether you tend to run hot or cold, and whether you sleep on your back or your side (and even if youre one of those weirdos who sleeps on their front).

• Big Agnes is a small, independent US outdoor brand out of Steamboat Springs, Colorado a small ski-town that weve never visited but which we like to imagine is full of mountain-loving, trail-hiking outdoorsy types. That would make sense, since the company makes some of the best ultralight backpacking gear around, including the award-winning Copper Spur, Tiger Wall and Fly Creek tents. It is kit that has clearly been designed by a gang of folks who love sleeping in the dirt just as much as we do here at .

  Oh, and if youre still wondering where the heck that name Big Agnes comes from, we did try to find out. Depending on who you talk to, its either an affectionate tribute to a legendary truck drivin mountain mama, or a 12,000 foot peak in the Mount Zirkel Wilderness. We kinda like the first one better.

The warmth of the bag is on point!
