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, it’s a pretty inhospitable place – and certainly not one to get lost, ranger or not. To survive in such a location you’d 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, it’s 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 won’t roll off in the middle of the night. In short, if you’re looking for a single solution to take camping, backpacking and everywhere in between from spring right through to autumn, you’ve 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 you’re one of those weirdos who sleeps on their front)

    • 3N1 System Bags offer three bag configurations for temperature versatility with a technical, roomy sleeping space that keeps you on your sleeping mat throughout the night 
    • Mat Cinch System is adjustable to a variety of sleeping mat sizes. The self-equalising drawstring easily connects bag to pad and the middle securement feature provides extra stability 
    • Maximum thermal efficiency is achieved when inner and outer bags are layered, using offset quilting to minimize cold spots 
    • Sleep on any side using the inner bag alone and within the outer bag. Three-quarter, anti-snag ambidextrous zipper stays out of the way when side sleeping 
    • The inner bag design mimics the award-winning Big Agnes Sidewinder sleeping bag, designed for side sleepers and made to move with you from side to side 
    • Keep your head snug and warm using the inner bag with jacket-style hood 
    • Spacious, rectangular shaped outer bag is constructed with draught collar, wedge, and two anti-snag dual side zippers with zipper garage 
    • Ultimate comfort and additional hand warmth with hand tuck pockets at the top of outer bag 
    • Access from top and bottom of both inner and outer bag with two-way zipper for easy temperature control throughout the night 
    • Easy access to pillow pouch on mat sleeve keeps your pillow tucked in all night 
    • Create a doublewide system bag by zipping two 3N1 bags together

  • Big Agnes is a small, independent US outdoor brand out of Steamboat Springs, Colorado – a small ski-town that we’ve 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 WildBounds.

    Oh, and if you’re still wondering where the heck that name Big Agnes comes from, we did try to find out. Depending on who you talk to, it’s 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!
