What To Look For
If you backpack in snowy or rainy climates, a waterproof sleeping bag is essential. As a backpacker, you know that down is the best option for sleeping bags not only for warmth, but also for compression size. When shopping for a waterproof down sleeping bag, you will have to consider and prioritize a few factors. The two biggest factors are the temperature rating and weight. Backpackers often opt for lighter-weight bags, but you might have to sacrifice weight for temperature rating depending on the weather you plan to backpack in. Other factors include the bag's compression size, the type of sleeping pad it is compatible with, breathability, whether it is windproof and price. Women backpackers can choose either a woman's sleeping bag or a traditional sleeping bag. Bags designed specifically for women are shaped to better fit a woman's body (usually more hip room and shorter length).
Common Pitfalls
When prioritizing selection criteria, backpackers will often rate weight and price as a higher priority than temperature rating. While you might like the price and weight, you could be in for some cold and sleepless nights if you do not choose an appropriate temperature rating. First, look at a bag's degree rating to ensure that it is appropriate for the weather where you will be backpacking. Always go for a bag rated lower than the lowest temperature you expect to sleep in. Why? Two reasons: 1) While you might not expect to camp in colder temperatures, elevation and weather changes could easily create an unforeseen condition; 2) Degree ratings are not an exact science. You could buy a 25-degree rated sleeping bag and be cold in 30-degree weather. It is easier to unzip the bag slightly if you get too hot, but it's not so easy to create extra warmth.
Where To Buy
When shopping around, consider more than just price when choosing which retailer to buy from. Check out the return policy. If you use the sleeping bag once and discover its waterproofing system is inadequate, make sure you can return the item for a full refund. Also, find out if a retailer charges a restocking fee. REI offers a great return policy: If you are unhappy with your purchase for any reason, you can return it for a full refund, not just store credit. Other reliable retailers with good return policies include: Moosejaw, Backcountry.com and Altrec.com.
Cost
Waterproof down sleeping bags vary in price depending on the weight, temperature rating and additional features. Prices range from $100 to more than $600. If you purchase your sleeping bag online, you might also incur a shipping fee (although many retailers offer free shipping for larger dollar amount purchases).
