Buyer’s Guide
When choosing a mummy sleeping bag, focus on temperature rating first, it determines whether you’ll stay warm in your expected conditions. Next, consider weight and packed size, especially if you’re backpacking long distances where every gram matters. Material durability is also important for long-term outdoor use, particularly in rough terrain or bushcraft environments.
Another key factor is season rating (3-season vs 4-season), which affects versatility across weather conditions.
One common mistake is choosing a bag based only on price without checking temperature limits. A cheap bag that doesn’t match your climate can ruin your trip.
