22" waist for my thin 7 year old was a good fit. Not adjustable but had a bit of room to grow into. Nice clean look. Looks good with tee or button down shirt. Nice material. Easy wash, no wrinkles. Got these at a very good price so keep your eyes open folks.These run quite narrow and skinny. Will be great if your son is not muscular and athletic in build. Fabric was more stiff than I expected from RVCA since their t-shirts are incredibly soft. I had to send these back.I love look of RCVA Pants on my teenage son. He really likes them. They are quality made. It is a nice change from jeans and shorts. It is a good brand for young men.These were great! A little longer than we wanted but that's an easy fix. Good quality and great fit everywhere else. Good price too. I shopped around for these exact pants and in retail stores they were much more.These are getting worn a LOT by my 13 year old. Standing up to constant washing and a pretty active lifestyle - plus he thinks they are cool. These do a good job meeting the needs of both teen age boy and Mom - pretty tough requirements list!These are the only pants my son wears! He has every color and I just order more as needed!!My 14 year old who usually wears a 16 fits in the 29 perfectly!My sons loves these pants. Fits true to size. Good quality and on time shipping. You can dress them up or down.Roomy enough to wear to the skate park.
