My 2yo looked great as Wolverine this Halloween!  I combined this with a set of soft claws that completed the costume wonderfully.  Unfortunately he lost the mask at some point during the night so if I track one down I will be adding an elastic chin strap or something but still the design was nice.  The mask was great because he could wear it over his face or just slide it back a little for better view and wear as a hat but still showed well for the costume.  He was sad that he lost it and this would make a great 'dress up' for the boys when their sisters are all playing with their dresses.  The muscles were a real nice addition and are very soft so no worries with stiffness.
Quality of the material is typical for an inexpensive costume but he wore it in and out of car, walking and riding in stroller and had no issues.  The actual suit is 1 piece which is also nice so you don't have to worry about the shirt riding up on him.  There was room under for laying if needed for cold weather.
I would purchase again.
