I had my son try 4 different helmets prior to deciding on this helmet. This helmet had the best fit. Although most of other helmets also had adjustable function, this one did the best job. Because it is comfortable, my son doesn't complain wearing this helmet. I highly recommend this one for toddlers/preschoolers. My son is 4.5 years old, but on the small side, about 10-20 percentile on his height/weight.
Bought this helmet for my 4 year old Nephew Fits him great and looks great. My nephew is addicted to paw patrol so when I found this helmet I had to get it. Goes great with his Paw Patrol Bike
