[Made with 650FP High-Quality Down] This down sleeping bag features high-quality, warm duck down that regulates your temperature while you sleep, allowing you to sleep soundly until the morning. It's lightweight and highly insulating. It's odor-free and gentle against the skin. The ultra-water-repellent 20D nylon outer fabric repels cold and moisture, and three different filling levels allow you to stay cozy until the morning.
[Mummy-style sleeping bag for easy compact storage] For winter, when warmth is important, the mummy-style sleeping bag is designed to fit the shape of your body, allowing you to sleep without feeling any pressure. It fits snugly over your head, with a three-dimensional cut that fits snugly to your body without any pressure! It also comes with a hood that covers your head, ensuring complete warmth. This is a useful item for sleeping more comfortably in cold weather, and its compact size means it won't feel like a burden when you're out and about. To prolong the life of your sleeping bag, store it in its dedicated mesh storage bag. It's compact when stored, and when removed, it absorbs air and expands, creating a fluffy, comfortable feel, making it as small as possible in your backpack. Storage size: SP400: φ16 x 34 cm, SP700: φ19 x 40 cm, SP1000: φ20 x 42 cm
[Internal box quilt construction] The box construction and three-dimensional leg section allow for ample leg room for extended stretches. The neck drawstring allows for easy temperature regulation, and the hat features a U-shaped windproof collar, ensuring warmth and comfort even during winter camping. This sleeping bag is limited to SP700g/1000g sleeping bags with a U-shaped windstop strip. The YKK double-sided zipper allows for smooth opening and closing. This allows for greater freedom of movement, freeing up your hands for a comfortable, unrestrained sleep.
[Appropriate Comfort Temperature] Choose a down sleeping bag that matches your desired temperature. It can be used in most harsh winter environments in Japan, including snowy mountains and extremely cold winters. Even those who give up on outdoor activities due to the cold can now go see the snowy scenery. Since it can get cold at night in the mountains, having one on hand will help protect you from the cold while you sleep, giving you peace of mind. SP400: -1.4 to 3.8°C, SP700: -14.5 to -7.3°C, SP1000: -18.6 to -10.8°C (We recommend using it with a mattress with a certain R-value. This not only prevents wear on the surface of the sleeping bag, but also doubles the product's heat retention.)
[Useful in a variety of situations] This sleeping bag is useful not only for outdoor activities, but also for sleeping in a car, napping at work, and as a mattress or comforter at home, even in emergencies. It's perfect for camping, mountain climbing, disaster preparedness, stargazing, fishing, cherry blossom viewing, and more. It's suitable for both men and women.
