huge fan of these shorts! they're pretty lightweight and waterproof! they will be great in the summer. I think these can also work for running. It has that smooth and breathable fabric. I just hope it doesn't pill. The shorts have 2 hooks and a button so it'll definitely stay in place. These shorts are a little long (I'm a petite/short girly and you can use my measurements as reference) but I did want something on the longer side. like if this helped!!
