baleafWomen's Running Shorts 2 in 1 Gym Shorts with Back Zipper Pocket Quick Dry Sports Hiking Workout

Will the rear zipper pocket fit an iPhone X?

Do you wear underwear with these? I see that they have some built in, and as I have never had shorts like this I don’t know?

Are these made in the USA?

I love these shorts so much! I would love some additional color options. Will there be new colors for this year?
