【All-Season Compatible & Envelope Design】Suitable for all seasons, from summer to winter. 1.4kg. You can choose according to your preferred scene. The biggest feature of this sleeping bag is its roomy envelope shape (approx. 210 x 75cm), so you won't feel cramped even if you stretch your arms and legs, and you can easily turn over. There's no feeling of pressure even when wearing thick clothes, and you can relax and sleep as if you were in your own bed. The 1.4kg type has a minimum usage temperature of -10℃. 【3-Layer Construction for Excellent Heat Retention and Durability】The outer fabric is highly waterproof and tear-resistant, making it suitable for harsh outdoor environments. The highly cold-resistant inner padding (stuffing) provides excellent cold protection. The soft inner lining feels like down, and warmth spreads from the moment you enter the sleeping bag, leading to a good night's sleep even on cold nights. Comfortable as if you were at home at the campsite. 【Functionality and Versatility】The hood has an adjustment cord and Velcro. It shuts out cold air entering from the neck and head. The sides have double zippers, allowing opening and closing from both the inside and outside. It can be opened and closed from the feet to the shoulders, making temperature adjustment easy. It has a small pocket inside to store your smartphone, and it is useful in all situations, including camping, BBQs, cars, mountain climbing, outdoor activities, stargazing, touring, cherry blossom viewing, overtime work at the office, as a substitute for a futon at home, and disaster preparedness. 【Lightweight and Compact for Easy Carrying】Ultra-lightweight design that is lighter than conventional models! When you unfold the sleeping bag, it naturally absorbs air and puffs up. When storing, remove the air thoroughly before rolling it up, and it will fit neatly into the included storage bag. Comes with a dedicated storage bag, making it easy to carry for mountain climbing and travel. 【Washable & Reliable Long-Term Warranty】Machine washable at home (laundry net recommended). You can keep it clean even after outdoor use. If you expose it to sunlight before use, the moisture will evaporate, and the sleeping bag will become even warmer. Because it uses high-quality materials, you don't have to worry about the inner padding shifting or shrinking even after repeated washing, and you can use it comfortably for a long time. K335
