Why I Care About the Material
For me, the fabric makes a big difference. I look for a jacket that can handle regular use without feeling too heavy or too stiff.

When I Think It Is Worth the Price
I decide a jacket is worth the price when it offers a good balance of durability, comfort, and condition. If the jacket is in excellent shape and fits well, I am usually willing to pay a bit more.
