Decided to try this replacement on a micro helmet before getting a new one, totally worth it! Fits perfectly and save at least $40.Happy mom, safe child scooting around!

This does exactly what it's supposed to, protect my noggin. Velcro works well and it fit my helmet (size s/m) I did a personal project of refurbishing my old skating helmet (which was a seriously bad way) and needed pad replacements (amongst other upgrades) since the original ones were dusty, moth eaten and just gross from old sweat. This pack fit the bill. No complaints so far! Not sure how durable they are. I plan on taking care of these better than the original set. But, even if they're not great there aren't many other options. Regardless, I'm not worried about that since it's def cheap enough to buy replacements as needed.

My girl is 8 years old, and I don't know how but she lost her bike helmet pad that's supposed to go on the very back of her head. This set of replacement pads are perfect in size and thickness. Very happy with the purchase!

I'm on my third Pro-Tec Classic Certified helmet, and there has always been a little too much space between the back of my head and the rear of the helmet. It's not a helmet size issue -- I've tried a size up and a size down, it's just the shape of my head. Although this liner is not an exact match to the ones on the CC, it was close enough, especially for what I had in mind.I used the rear pad from this liner kit and glued the original PT rear pad on top of it using Fabri-Tac, an adhesive for fabrics. Do not use too much Fabri-Tac in one area because you will have hard, dried glue -- like little plastic pebbles -- in between the pads, and do not press down too long when setting the two pads together or the Fabri-Tac will seep deep into the pads and will compress the foam pads when it dries. I used the velcro included to fasten around the corner points of the new rear pad to secure it to the helmet. It worked great. I'm pretty sure I have one of the most perfectly fitting Pro-Tec helmets at the park now when I ride.As for the foam pads that came with this kit I haven't used, I'm sure I'll find a use for them soon (The thin fabric lining on my front pad is already, to use a skate/snow term, "delamming" from the foam).NOTE: This was done on the Pro-Tec Classic CERTIFIED (sz: Med), NOT the Classic, or any other Pro-Tec helmet models. I've had the Classic in the past, and the Classic liners are completely different from that of the Classic Certified! I suspect the liners are different between all Pro-Tec models.To those complaining about the thickness of this liner: I used to be a snow tech that sometimes helped out at the skate side of the shop I worked at. The possible reasons why this liner kit seems to be "too thin" for your helmets are:1) You have a helmet that does not fit you (or your child) properly.Do NOT buy a helmet online without trying it on first in real life. Go to a proper bicycle, snow, or skate shop with knowledgeable employees that actually research and use the products they sell. They know how important safety is, because they have seriously injured themselves multiple times already. Even the most cynical skate shop employee will assist the most novice of customers on the proper fit and usage of safety equipment.Do NOT buy a size above what fits your child now thinking he or she will outgrow the helmet in 6 months. Buy another helmet when your child outgrows his or her current helmet. The main reason you are buying your child a helmet is to protect your child, NOT to save money.All manufacturers have variation in sizes. That is to say, a medium Pro-Tec helmet will probably not fit the same as a medium Triple 8. Again, if you're going to buy a different helmet brand or even model from the same company, TRY IT ON IN REAL LIFE FIRST!2) If this liner kit seems much thinner than that of the ones you are replacing, take a good look inside the helmet. If the only thing between your head (or your child's head) and the plastic outer bucket is a thick liner, then that helmet does not have an inner bucket made of EPS foam and is more than likely not CPSC and ASTM certified, which will GREATLY increase you or your child's chances of serious head injury or death. What you want to see is an inner bucket, about an inch thick, of EPS foam (looks and feels like hard styrofoam) that covers the entire inside of the helmet, then a liner such as this, possibly thicker, but not by much. That EPS foam will compress in a predictable manner help disperse the energy from the initial point of impact through out the helmet, bettering the chances of survival. If you or your child is wearing a helmet without EPS foam and is not CPSC and ASTM certified, you might as well be wearing a hat to protect yourself. If you don't believe me, check out YouTube. There's a bunch of videos that demonstrate the effectiveness of a certified helmet vs a non-certified helmet.

the foam is a bit thinner however is VERY Comfortable. Used it for my Sandtrooper helmet, and with how many parts I have in my helmet (fan etc.) it leaves room that is needed and is very easy to get it placed!
