I ordered the puffer vest in a size 18, black. My son is 12, 5'3'', 86lbs, and wears a 14/16 shirt/top. Since he's entering a period of rapid growth, and he's been in14/16 for the past year, I sized up to an 18. This jacket is true-to-size. He LOVES it. He has never been a fan of the usual puffer vests, until I showed him the quilted pattern on this one. He loves the look and I do too. He also loves the fit and feel of this vest as well as the BIG, INTERIOR POCKETS on both sides! He says this is now his favorite. It's warm, but allows for ventilation and unrestricted movement. This vest is well-made of quality materials. I'm glad I sized up, because he will get a chance to wear it through the rest of this season and maybe next fall/winter too. I wonder if this vest comes in adult sizes for my teens, because the older brothers really like this vest too. See my attached pictures. I highly recommend!
