Adjustable helmet with improved strap assembly!
EDIT: Couple years after I wrote the original review the seller reached out and said theyd read my comments and had revised the chin strap + buckle assembly to be hassle free. They wrote probably the kindest email I've ever received from an Amazon seller and sympathized w the headaches w small kids. Then they offered 2 brand new helmets w the new design as a replacement. Pretty neat deal.So here's what changed! They took my suggestion to cap off the end of the nylon strap with a rigid piece (where I'd just used duck tape) so it won't slip out of the adjustable part. Also the strap feels a little less flimsy than before. My main issue had been a overly thin strap that just threaded right out of the red plastic adjuster when kids were just being kids. Problem no more! Be sure to check out my latest pics (3rd - 5th ones) where I tried to compare the two in hand.Also on the original helmets, I've been impressed by the build quality. Our kids tend to drop them in the garage rather than gently place them on handlebars when they're done. Never had a crack or piece just snap off so really these are built to last.Major kudos to the seller for leveling up their R&D and coming up with an even better product!OLD REVIEW BELOW:Hey there! I'm guessing you're a parent or grandparent who wants to keep your kid safe, not break the bank, and find a helmet that will last longer than 6 months! This item checks a couple of those boxes but not all of them. Fit is great on our 7 yr old and decent on our 5.5 yr old... But he'll grow into it just fine. Older kid is very careful with things so the helmet will outlast her in terms of sizing. It's nice that it'll adjust and really get snug so it sits properly on their head. A helmet that's flopping around does no good when a kid bails on their bike or falls over.This could easily be a 5 star item if theyd just spend a little more on the strap assembly. See, the strap is too thin for the red 3 toothed piece that clicks it into place. The problem is that piece can slide around at will and it'll come off almost every time your kid wears this. It's been less problematic with our more careful child, but a physical and boisterous kid? They'll yank the thing off every time and you get to Jimmy rig it back together. No fun. The manufacturer just flat went cheap here and didn't put a stop mechanism or glue or anything to hold it on the strap. Their solution is another cheap piece.. The chin strip with a marginal amount of velcro. I suppose it the chin strap was fatter and had more grip to it, then it would hold the strap in order. But both of those could be remedied if they wanted to.See my solution in the pics. I duck taped where the ear hole should form (midway up the strap), then duck taped the very end of the strap to itself so that there's an end piece that the red clip cant slide over. If you wanted to go further you could duck tape the entire strap "shut" so that the clip won't move at all. Measure to your kids face and then lock it all in place.

Perfect fit
I purchased the helmet for my 8-year old daughter and it was just right. I like being able to adjust the back side of the helmet for a perfect fit so it’s not too loose or too tight. The strap that goes under the chin is also very comfortable. The helmet’s vents are also great for these hot days. The only thing I’m a bit iffy about is the visor. It hasn’t given us an issue yet. However, when I was clipping in onto the helmet it did seem a bit flimsy. I hope this doesn’t break off with ease after a few months. Nevertheless, my daughter loves the helmet and we definitely recommend.

Great bike helmet
Got this for my youngest grandson who just got into bicycle riding. Recently he crashed and burned, and his head went down on the pavement. So glad we had this nice helmet for him as there was no damage done.

Great product for the price.
The design and colors caught my eye as it is very appealing. At the price point and reviews I decided to give it a try and was very pleased. My daughter has not complained about the fit and I believe it was a good choice for her. I was able to adjust it for the best fit.

Cute helmet, buckle fell off rendering it useless
Edited!The helmet is cute and sturdy but the buckle literally fell off within a few months, and it is an off size so it difficult to find a replacement.The seller immediately contacted me and offered to rectify the issue. Proactive customer service gets a 5 star review from me always.

Bike helmet for Grandson
This helmet was for my 8 year old grandson for his birthday. He loved the blue color and how he could take visor off if he wanted. It fit well. So far it seems sturdy and the adjustability is good.
