Cashmere, in terms of warmth retention effect, can be said to be a well-deserved champion, and it is also the top-grade warmth retention fabric at present, so the pants made of cashmere are definitely in the top of the list in terms of warmth retention, and of course, they are also the most expensive. Real cashmere pants are generally more than several hundred yuan.
Lamb wool, lamb wool and cashmere are only one word apart, but they are different fabrics. Lamb wool is mixed with polyester and acrylic fibers, which feels like lamb wool and has a good warm effect, but it is artificial wool, so the price is much cheaper than cashmere, and it is also extremely warm.
Derong, choose warm clothes. Derong is very nice. It is also the mainstream warm fabric. Its advantages are light weight, low price and good warm-keeping effect. It may not be as good as cashmere and lamb down, but it is warmer than most pants.
The warmth retention of modal plus cashmere trousers is also worth considering, and it is also a very comfortable fabric now. Advantages can refer to the advantages and disadvantages of modality. The warmth retention effect after adding cashmere is very strong, but it mainly depends on the thickness of cashmere. The thicker the thickness, the higher the warmth retention.
Down, down is down, but it is very different from the above. The warm-keeping effect of down trousers is definitely one of the best, but they are generally not worn because they are relatively thick. The warmth of down trousers depends on the padding inside, just like down jackets.
