睡袋 (shuì dài): 寝袋

On the first night of camping, the temperature in the mountains dropped to minus five degrees. Luckily, I had brought a thick sleeping bag. Once I crawled inside, I warmed up quickly and slept soundly until dawn.

This outdoor gear store was having a sale, so I spent two hundred yuan on a lightweight sleeping bag. When packed, it's only as big as a water bottle—perfect for backpacking trips.

In the middle of the night, it suddenly started pouring rain, and water got into the tent. My sleeping bag was completely soaked, and I was shivering from the cold, so I had to run to the car and sleep with the heater on all night.
