How to choose a cold-weather sleeping bag
The temperature rating is the first thing to check, but read it carefully. Bags list a comfort rating and a lower limit; for cold-weather use, choose a bag whose comfort rating sits a little below the lowest temperature you expect, since ratings assume you are using a sleeping pad and wearing base layers. A mummy shape traps heat far better than a rectangular bag because it reduces the air your body has to warm.
Insulation type is the key trade-off. Down is lighter, packs smaller, and lasts longer, making it ideal for backpacking, but it loses warmth when wet unless it is treated. Synthetic insulation is bulkier and heavier but keeps insulating when damp and costs less, which suits wet climates and budget-conscious campers. For down, a higher fill power (around 650 to 800) means more warmth for less weight.
Construction details lock in the heat. Look for an insulated draft collar around the shoulders, a draft tube behind the zipper, and a snug, adjustable hood, since a huge amount of heat escapes from your head and neck. A pad sleeve or anti-slip fabric keeps you on your sleeping pad, and a sturdy two-way zipper with anti-snag tape prevents frustrating jams in the cold.
Pick a rating with margin for the conditions, choose down or synthetic to match your climate and budget, and pair it with a good pad so a cold-weather bag keeps you warm through frosty nights.
