My son has autism so he has a lot of sensory issues. Why I always look for things he can move around in. I love that these have real pockets and real drawstring. My son is tall and athletic for his age so usually things won't fit right either to short or fit him right in length but to big in width. These are nice because I can tighten the waist a bit but still a little bulky in the leg because he's got long lean legs. He's constantly moving and jumping so these are great for that plus I love the 2 different colors or split colors. Super cute!
