I was initially concerned that this item would not fit my son's head, as there is no option to select a specific size. According to the size chart he would need an XXS, but the item is actually one size fits all. I ordered anyways because the item did not cost much, so if it did not fit I would not have wasted much money. However, I am pleased to say that the durag fits my 16 month old son perfectly! Simply tighten or loosen the strings to taper the fit.
