Amazon Essentials Men's Athletic-Fit Casual Stretch Chino Trouser (Available in Big and Tall)

What is athletic fit?

I am definitely a 38inch waist and 30 inch inside leg. If I order 38/30 will they fit ? ...or do I need a size down (36/29) ?

How long will it take for my refunds to go back to my bank account thanks mr grana

Do they have a stretchy waist like the gap ones?
