Whether it's a cool summer evening or crisp shoulder-season nights, the EXPED Mega Sleep 25/40 Sleeping Bag is in our bedtime setup. The synthetic fill traps in warmth for staying cozy in the warmer months, while the wraparound zipper lets us use it as a quilt atop a colder setup for added warmth when temps start to drop.

Summer camping can lead to some Goldilocks-style discomfort: bag on, way too hot, bag unzipped, suddenly we're getting blasted with cold midnight breeze. Luckily, with the inspiration of the most versatile jackets out there, the Lost Ranger UL 3N1 Sleeping Bag is just right. Two sleeping bags—one in a lofty, lightweight rectangular shape and one mummy modeled after Big Agnes's Sidewinder bags—can be slept in together to offer cool-weather warmth when we need it and used apart for hot summer nights.

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.

Whether we're backpacking or car camping, sleeping under summer stars or on top of crunchy autumn leaves, the Lost Ranger 3N1 Sleeping Bag is a cozy camp companion. Similar to a three-in-one jacket, this sleep system features two sleeping bags that can be used separately or mated together depending on the temperature, season, and conditions. Even together, this bag is light and packable enough for backcountry adventures.

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.

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.
