Thank you for viewing. This item was purchased in October 2025. I planned to use it, but due to bad weather, I didn't have the opportunity. I unfolded it and tried it out at home, but I haven't used it for sleeping. I'm selling it because I bought something else. There is a stain on the underside of the surface. Please refer to the photos. Weight: 2.2 kg Color: Olive Comfort temperature, size → Please refer to the photos. Although it hasn't been used in practice, it is still a used item. Please refrain from purchasing if you are concerned about minor fraying or the aforementioned stain. Thank you for your understanding. The following is an excerpt from the website: * 【About the warmth of artificial down】CAMDOOR sleeping bags contain 100% no animal ingredients and are environmentally friendly and recyclable. Artificial down does not contain animal protein like feathers, so it does not have the unpleasant animal odor of feathers. The fiber structure of artificial down artificially reproduces the fiber structure of feathers, achieving warmth, softness, and lightness. This material can be easily washed at home and combines the advantages of down and hollow cotton. It has excellent heat retention and breathability. It is warmer and softer than sleeping bags made of the same weight of batting material on the market. You can sleep soundly without being disturbed by the outside air. Ideal for outdoor activities, camping, car camping, mountain climbing, travel, cherry blossom viewing, and disasters. * 【High-quality nylon material】The outer material of the sleeping bag uses highly waterproof nylon material, which has superior waterproofness and tear resistance compared to commercially available sleeping bags. It is difficult to tear even when pulled, and it is resistant to oil, seawater, and mold. The inner fabric uses 100% soft polyester, which has excellent heat retention and breathability. Even if it rains or mists, the waterproof function allows you to spend your time without getting wet. It is ideal for use in winter. Even if you spill a drink or water, you can wipe it off with paper. The outer fabric is a matte fabric used in down jackets, giving it a luxurious feel. Down has low moisture permeability and is difficult to dry even when wet with sweat or rain, while Tetron is bulky and lacks heat retention. The CAMDOOR sleeping bag was born to overcome the shortcomings of both.
