Tight clothes look better, but they are not good for blood circulation. Loose is a bit bloated, which is better for health. See what you like better.

Tight cotton trousers feel warmer because there is no air leakage, but pants made of windproof fabric are better, and down trousers are a good choice. Four-layer anti-down treatment is more windproof and warm, and a lot of white duck down is added inside.

I think it's better to wear warm pants. Because of 1, it is warmer, more comfortable and more skin-friendly. There will be no chance for air to enter. The second reason is that wearing tight pants can better show people's figure, especially girls, who like to wear tight pants, but it is not good for boys to wear tight pants. Boys suggest wearing loose pants. Boys generally don't care about their figure and try to wear comfortable pants.

Too tight can't keep warm, but a little gap and space will keep warm better. Just like the clothes, cotton-padded clothes and shoes we wear, if there is no space at all, its warmth will be reduced, just not as good as the kind with a little space.
