I use this for HIIT, cardio, and weight lifting. Good fit and not bulky. The liner has a nice feel and is not too snug so it doesn't ride up the leg. I would definitely buy this product again and again. However, I was surprised that the drawstring isn't a little longer, the pocket on the top back middle fits a key or lip balm, probably great for running with your house key, but that's about it... and I haven't figured out a use for the little bungee pockets on either side of the zip pocket. I do wish there was a deeper pocket or something that could fit a phone. A pocket like on the front right of the ferrosi shorts maybe.
