About this product Black 1.0kg [Practical Envelope Design, Comfortable Sleep] This is an envelope-style sleeping bag that offers a relaxed feel like a futon. Compared to mummy-style sleeping bags, its roomier size prevents a feeling of confinement. The spacious interior allows you to stretch out your arms and legs without feeling cramped. There's enough space to turn over comfortably without stress. The ample cushioning envelops your head and back, providing a cozy sensation. [Excellent Practicality] When camping, especially in locations with significant day-night temperature differences, a thick sleeping bag is necessary to stay warm. To fully enjoy camping, outdoor activities, and leisure, a comfortable sleeping bag that allows for deep sleep is essential. [Sleeping Bag Pocket] Allows you to store small items like watches and mobile phones. [Windproof Cover to Keep Your Feet Warm] Unlike traditional sleeping bags, we have developed a sleeping bag that allows you to adjust the temperature at any time. There is a cover at the bottom of the feet to prevent cold wind from entering the sleeping bag, making it very warm even when used outdoors in the cold. You can enjoy a warm sleeping bag experience anytime. Additionally, when it's hot, there's another zipper at the bottom of the feet that can be opened. You can fold the foot cover back to allow for air circulation and lower the temperature. You can sleep comfortably with your feet out. Furthermore, by pulling the foot zipper, you can extend your feet, allowing you to move freely while wearing the sleeping bag, making it more convenient to use. [Two Zippers, More Convenient] The sleeping bag has two zippers, and a zipper has been added to the feet. The zipper makes it easier. It's a two-way zipper with an inner zip, so it can be opened and closed from the top of the sleeping bag. You can use it comfortably without feeling restricted or annoyed during use.
