Pleased with this product, good quality with affordable priceFirst of all the stitching and material feels neat and comfotable, looks like a good quality product and it is. If there were something to complaint, the compressed packing size is kinda big and would take a lot of space.I tested it in the park near my house after receiving it. I thought it was warm enough, and it was. I felt warm and fell asleep quickly. But I was woken up by chill at midnight. I forgot to count the damp weather in and the sleeping bag got a little wet which comprised the heat retention drastically. Fortunately, I always carry emergency sleeping bag if I were staying over night. And it was amazingï¼After I put this sleeping bag into my emergency sleeping bag. I felt so warm, even a little sweaty. I would recommend you buy one in extreme cold weather as a compliment. The oaskys Camping Sleeping Bag is warm and breathable but you'll need a heat insulation and reflector like my bearhard emergency sleeping bag( if you need one,here's the link(https://www..com/s?k=emergency+sleeping+bag&hidden-keywords=B07RV3GYNN&ref=nb_sb_noss_1). It's almost like fleece and technical jacket only works best together. This might be useful if you're planning to go camping in the wild in winter.
