Question: I would like to buy a safety helmet for my granddaughter who have 6 years old. It's good for her?
Document: Got this helmet to match her bike - she is 4 years old and the toddler helmet would have been too small. Very happy with purchase!! !
This helmet fits my 4 year old (who is the size of an average 6 year old) perfectly. The helmet arrived promptly, and was exactly as pictured. We are very happy with this purchase! Thank you! :)
Fit nicely for a 4 years old kid, plenty of cushions around, fit snugly. Useful visor,. Graphics are nice as well.
Our four-year-old granddaughter is obsessed with all things Disney Princess, so we got her this helmet to match her new Disney Princess bicycle. Her parents insist that she never get on her bike without having her helmet on which is absolutely no problem -- she loves the helmet so much that she just wears it for fun. It&#8217;s lightweight, stylish, fits comfortably, and was not expensive.
There is some basic information about this helmet that is missing from this product's page that should be included. Now that I have received the helmet and had a chance to look it and its packaging over, let me provide it for you.Recommended ages 5 and up.
My granddaughter don't miss much, and to see her look over the princess attire on the helmet and get her approval was priceless. Made Grandma proud!
The rear and sides of the head are cradled by a flexible plastic frame that uses an elastic band in the very back to stretch to fit the child's head. Normal adjustable pinch guard strap goes around below the chin.The princess designs have glitter in their dresses and tiaras/headbands.Good helmet, -1 star for lack of important information on the product page.
Answer: yes
