They open completely, so they are easy to unzip at the top if it's a humid or hot night. 40 degree sleeping bags are great for warm weather trips, so they help vent heat, keeping you cool if a hot front comes through. They are typically lighter, so they might not provide the highest degree of insulation, but what they don't have in terms of insulation, they make up for in their weight. Engineered for maximum warmth, they will also keep you snug on your next outdoor adventure. Camping sleeping bags are designed to withstand a variety of climates and terrains, standing up to wear and tear for those extreme outdoor trips. However, they are heavier than backpacking sleeping bags, which can make traveling long distances quite difficult.
