TARSE Womens Wide Leg Pants Casual Loose Yoga Sweatpants Comfy Lounge Pajama Flowy Pants Pockets

Are they good for yoga? I want one that is comfortable and not tight

Do these pants get pilly or rough where they rub against each other (thighs) or other material (like handbags swinging by a hip)?

Are the pockets functional enough to hold a cellphone?

I'm 5'9'', 150-155 lbs, L or XL should i get?
