Sleeping Bags

Four-season performance in one sleeping bag? It's unheard of, so Big Agnes created a clever solution: a three-in-one design. The Lost Ranger UL 3N1 Sleeping Bag is two ultralight sleeping bags that are still comfortably light together while we're backpacking in winter conditions. The rectangular outer bag is great for warm summer nights, and the inner Sidewinder mummy bag is ideal in the shoulder seasons. Together, they deliver zero-degree warmth so we can explore all year round.

Fit & Design: Adaptable design offering 3 bag configurations in 1 simple-yet-technical sleep system System consists of 2 down-filled bags that can be used together or separately, depending on your sleep style and temperature preference Maximum warmth is achieved when the inner and outer bags are layered, using offset quilting to minimize cold spots—this combined configuration has a tested lower limit of 15°F Using the inner bag alone provides warmth down to about 35°F; the outer bag alone provides warmth down to about 50°F 650-fill-power DownTek™ down repels water while maintaining its insulating value Water-repellent finish is PFC free Sleep on either side using the inner bag alone or within …

Imagine a single sleeping bag that's light enough for a backpacking trip, warm enough for sub-freezing temperatures, and simultaneously cool enough for summer stargazing. The Lost Ranger 3N1 Sleeping Bag might not be exactly that, but it does borrow tech from versatile three-in-one jackets to create comfort no matter the season. A light and lofty rectangular bag is fit for warm summer nights, the inner mummy-style Sidewinder bag delivers comfort for the shoulder seasons, and together, the two create insulation rated for zero-degree sleeps.

The Lost Dog Sleeping Bag stands up to any shoulder season adventure you've got planned. At just over 2 pounds, this sleeping bag is light enough for high-mileage treks without sacrificing comfort—like a draft collar, single-handed cinch hood, and free-range footbox. Create additional comfort by zipping the bag to another bag from the Big Agnes line to snuggle up with your partner for an even warmer experience. And by sliding your sleeping pad into the pad retainer, you can ensure full-coverage even if you both toss and turn throughout the night.

Lighter than before, the Mountain Hardwear Lamina Sleeping Bag seals us up in synthetic insulation to keep us warm in cold and damp weather. The standard mummy cut is warm, efficient, and shaped for women's bodies, and the zoned insulation maximizes warmth where we need it most while cutting weight where we need it less. We also like this bag for wet or humid conditions because the durable water-repellent finish protects against moisture while the synthetic fill is a safer choice than down when there's a risk of rain, condensation, and sloppy campsites.

Now with a hardier, more compressible build, the Mountain Hardwear Lamina Sleeping Bag gives us warmth we can depend on. The ultralight ripstop material and lofty Temperlite fill lower gram count and bulk yet don't flinch in harsh conditions, promising lasting heat-trapping performance. Plus, Mountain Hardwear's proprietary seamless Lamina construction enhances the fill's loft and eliminates cold spots for 360-degree coziness.

With the Mountain Hardwear Lamina 0F Synthetic Sleeping Bag, we're ready to camp in the cold temperatures of the high alpine. Filled with Temperlite insulation, the Lamina has the loft and warmth to keep us cozy but in a dramatically lighter package to help with our pack load. We love the expected comfort that comes with its ergonomic shape and cozy collar and hood, but where the Lamina really shines is in its unique baffle construction that maximizes the insulation's loft and concentrates warmth where we need it most.

Synthetic insulation used to be synonymous with heavy and bulky— not so with the Mountain Hardwear Lamina Sleeping Bag. The synthetic fill is less fussy than down, keeping us insulated even if the bag gets damp from rain or snow. It also features a double draft collar and bidirectional insulation baffles to eliminate cold spots and keep us as toasty as possible. We like how this bag keeps us warm and comfortable deep in the wilderness without making the journey feel like the slog.
