Sleep Well: Finding the Right Sleeping Bag
Sleeping bag technology has come a long way from the days of cowboy bedrolls. These days, there are a number of high-tech materials and designs available to keep you warm during the coldest outings. Here's a short list of things to keep in mind when you're shopping for a bag:

Buy for Cold
It's a safe bet that on at least one of your adventures, the nighttime temperature will drop unexpectedly. That's why it's smart to buy a bag that's rated for the lowest possible temperature you expect to face on your camping and backpacking trips. For summer trips, a bag rated at +35 degrees or higher will likely do the trick. If you like to camp in higher elevations in the summer, or if spring and fall outings are in your future, consider bags rated from +10 to +35. Winter adventurers should look for bags in the -10 to +10 range, while those on serious winter alpine climbs and expeditions will want a bag rated lower than -10.

Keep in mind that sleeping bag manufacturers' temperature ratings only estimate the minimum temperature at which the bag will provide warmth. Take these numbers with a grain of salt, as different folks generate different amounts of heat when they sleep. If you're the type who likes to pile on the covers even on warmer nights, go for a bag that's rated ten degrees colder. The opposite is true for "warm" sleepers--a 35-degree bag will probably work for you on a 25-degree night.

Goose or No Goose?
The most important component of any sleeping bag is its insulating material. Modern sleeping bags offer two choices: goose down or synthetic. While both materials have advantages and disadvantages, down bags are considered superior because of their phenomenal warmth-to-weight and warmth-to-bulk ratios. While providing great insulation, down is extremely compressible and light. There's a reason why geese can fly and stay warm through the winter! Down also boasts great long-term durability and will typically retain its insulating properties after years of use.

All of that said, there are many high-quality synthetic bags on the market and synthetic materials are getting better all the time. While a synthetic bag will weigh somewhat more than a down bag at an equivalent temperature rating, synthetic bags perform better when wet. (Yes, the Achilles heel of down is that it loses all insulating properties when wet.) If your trips take you to wet climates, you may want to consider a synthetic bag for this reason alone. Keep in mind, too, that many people are allergic to down--synthetic bags are non-allergenic. Finally, down is considerably more expensive than synthetic, which might tip the balance for adventurers on a budget.

Bags for All Shapes
Sleeping bags come in two basic shapes that reflect their intended use. Mummy-shaped bags offer the best warmth because they conform to the body's contours. This minimizes the amount of body heat the body must put out to maintain a constant temperature. Many mummy bags are offered in women-specific shapes and sizes, as well. Rectangular bags, while they do offer more room to toss and turn, are less thermally efficient because they contain more open air space. Also, they are typically heavier than mummy bags, and are generally not offered with down insulation, making them best suited for car camping or short backpacking trips.

Pad Yourself
No matter what kind of bag you choose, a sleeping pad is a required accessory. Not only do they provide much-needed comfort when sleeping on the ground, pads also offer crucial warmth for your backside, as the weight of your body compresses--and renders virtually useless--the sleeping bag insulation that lies beneath you.

Customer Review: Love this bag!
Wife and I were looking for a more cozy experience for our camping trips. We loved the idea of a double sleeping bag. The beauty of this bag is you can have 2 singles or one double. It was big enough for us and our 3 year old. Was almost too warm for the lower 50 degree temps. Pillows were a bit flimsy but did ok. Very comfortable and was shipped quickly! Recommend it.
Customer Review: Perfect sleep system
This is the first sleeping bag that makes sense. It's perfectly make. We were amazed at the quality. We were comfortable and together. The matching pillows are a nice touch. I thought we were getting pillow cases, much to our surprise they were pillows! This wasn't listed in the description. Finally, at the end of our camping trip the sleeping bag was packed as one unit... and it fit in the duffel bag without a hassle.

Wonderful product! Very cute; great quality. This is something the kids can use for many, many years!!
Customer Review: Fantastic bag for a kid
This is the perfect sized bag for a child. I bought it for my 3.5 year old, and I think it will last until her tweens. Because it is a little smaller than a regular bag, you don't have to fold it before rolling it, which makes it MUCH easier to roll than an adult bag.
