The hat runs small .Nice jacket and snow pants at a good price. Fleece lined hood and upper jacket. Sleeve cuffs have elastic. The snow pants also have and inner elastic cuff. My sons is between and 3 and 4T so I went with the 4T to give him room to grow. It is a bit big but still wearable with the cuff sleeves. Good thickness for a winter jacket. Warm but not so thick he can’t run around in. Very happy with the product thus far.Wonderful snow suit set! Jacket and pants are great! Hat matches but not very warm.I bought this big to last for 2 yearsNice snowsuitAfter only two uses, the zipper failed and my grandchild was told not to wear it to school again because the teachers could not get the zipper to zip.This item was delivered without snow pants, just jacket
