This is a sleeping bag made with plenty of brushed fabric from Yetina. It's approximately 192cm long and 70cm wide, so even tall people can comfortably sleep in it. Plus, Yetina fabric itself stretches, so it's stress-free. It can be used alone in spring and summer, as an inner layer for a sleeping bag in autumn and winter, or it can be extremely useful for its heat retention during camping or car camping. It's a must-have item. A completely limited edition. It's probably rare because it's hardly ever available on Mercari. It's in very good condition, having only been tried on two or three times.
