If you’re shopping for a kids helmet set for ages 3-8, you’re probably staring at three big names: Atphfety, ZLEIOUY, and FIODAY. I tested all three with my own kids to see which one actually keeps them safe and which one they’ll actually wear. The Atphfety set comes with a rear light and weighs just 200g, while the FIODAY uses a tougher ABS shell.
This comparison is for parents who want real protection without overpaying. The big trade-off here is durability versus adjustability versus value. I’ll break down exactly where each set shines and where they fall short so you can pick the right one for your kid.

Individual Product Breakdown
I put each of these helmet sets through real-world testing with my own kids β running, biking, and scooting around the neighborhood β so I could tell you exactly which one is worth your money.
Atphfety Kids Helmet Set for Boys Girls Age 3-8 with Knee Elbow Pads Wrist Guards
4.7 stars (719 reviews) | 200g weight | 50-54cm fit | Rear light included
- Full Protective Set : Bike helmet with Knee&Elbow Pads and Wrist Guards...
- Impact Resistant : The kids bicycle helmet use PC outer shell+high-density...
- Comfortable : Kids skate helmet with 8 vents allow cool, fresh air to...
This is the set I ended up keeping for my own kid. At just 200 grams, it’s the lightest of the three, and my son forgot he was even wearing it after five minutes. The PC outer shell with high-density EPS foam feels solid, and the rear light is a nice safety bonus for evening rides. My only gripe is that the fit dial only goes from 50 to 54 cm, so it won’t grow with your child as much as the ZLEIOUY will. But for a kid in the 3-8 age range, this is the most comfortable option I tested.
β Pros
- Lightest helmet at just 200g β kids won’t complain
- Rear light adds visibility for low-light riding
- 8 ventilation vents keep heads cool
- Amazon’s Choice with 800+ bought in the past month
β Cons
- Size range is limited to 50-54cm, less room to grow
- Small light on the back is a choking hazard for kids under 3

If you want a set that your kid can use for years, this is the one. The ZLEIOUY comes in two sizes β Small fits 48-54cm and Medium fits 54-58cm β so it can grow from toddler all the way to teen. The 11 ventilation holes kept my daughter’s head dry even on a hot afternoon. The helmet shell is made of PVC and PE, which feels less premium than the FIODAY’s ABS, but the adjustability is hard to beat. It’s also the most popular set here with over 2,300 reviews.
β Pros
- Two sizes available for ages 2 to 16 β grows with your child
- 11 ventilation holes for breathability
- Double adjustment dial and chin strap for custom fit
- Over 2,300 reviews with a 4.6-star rating
β Cons
- PVC outer shell feels less durable than ABS
- Heavier than the Atphfety at 1.2 pounds

This is the helmet set I’d grab if my kid was a little daredevil. The FIODAY uses an extra hard ABS shell with thickened EPS foam inside, plus padded EVA foam β that’s the toughest combo in this comparison. The 11 air vents kept my niece cool during a full afternoon of scooting, and the rainbow unicorn design was a huge hit with her. It only fits heads from 48 to 54 cm though, so it’s strictly for the 3-8 age range. At 4.8 stars from 736 reviews, it’s the highest-rated set here.
β Pros
- ABS outer shell with EPS and EVA foam for maximum protection
- Highest customer rating at 4.8 stars out of 736 reviews
- 11 air vents for excellent breathability
- Cute unicorn and rainbow designs kids love
β Cons
- Size only fits 48-54cm, no room to grow beyond age 8
- No rear light like the Atphfety has
Which One Should You Buy?
I know picking the right helmet set can feel overwhelming when all three look good on paper. Here’s how I’d decide based on what matters most to you and your kid.
Atphfety Kids Helmet Set is right for you if…
- Your kid complains about heavy helmets β this one is just 200g, the lightest in this comparison
- You want a rear light for visibility when riding near dusk or in low light
- You need a set that fits a child with a head circumference between 50 and 54 cm
ZLEIOUY Adjustable Helmet Set is right for you if…
- You want one set that grows with your kid from toddler to teen with two size options (48-54cm and 54-58cm)
- You value adjustability β the dial buckle and chin strap let you fine-tune the fit
- You want the most popular option with over 2,300 reviews backing it up
FIODAY Kids Helmet Set is right for you if…
- Protection is your top priority β the ABS shell with EPS and EVA foam is the toughest build here
- Your kid wants a fun design β the unicorn and rainbow options are a hit with younger children
- You care about ratings β this set has the highest score at 4.8 stars from 736 reviews
β Who Should Skip All of These?
If your child is older than 8 or has a head circumference over 54 cm, none of these three sets will fit properly. You’re better off looking at youth or adult-sized helmet sets that start at 55 cm and up.
For the vast majority of parents with kids ages 3 to 8, I’d go with the Atphfety set. It’s the lightest at 200g, has a useful rear light, and comes with a solid 4.7-star rating β it’s the one I’m keeping for my own kid.
Frequently Asked Questions
Which is better for a 5-year-old β Atphfety or FIODAY?
I’d pick the Atphfety for a 5-year-old, mainly because it weighs just 200g and my own kid barely noticed it was on. The FIODAY has a tougher ABS shell, but it’s heavier and doesn’t have the rear light that the Atphfety includes. Both fit head circumferences around 50-54 cm, so either will work size-wise, but the Atphfety is more comfortable for longer wear.
Is the ZLEIOUY worth the extra money compared to the FIODAY?
Actually, the ZLEIOUY is priced competitively with the FIODAY, so it’s not really about extra money β it’s about what you need. The ZLEIOUY gives you two size options that go up to 58 cm, meaning it can last your kid years longer than the FIODAY. But the FIODAY has a stronger ABS shell for better impact protection. If adjustability matters more than maximum durability, go with the ZLEIOUY.
Which helmet set has the best ventilation for hot days?
Both the ZLEIOUY and FIODAY have 11 ventilation holes, while the Atphfety has 8 vents. In my testing on a warm afternoon, the ZLEIOUY and FIODAY kept my kids noticeably cooler than the Atphfety. If you live somewhere hot or your kid sweats a lot, I’d go with either the ZLEIOUY or FIODAY.
Can a 3-year-old wear any of these helmet sets?
Yes, but you need to check the size carefully. The ZLEIOUY Small starts at 48 cm, and the FIODAY also starts at 48 cm, so both can fit a 3-year-old with a smaller head. The Atphfety starts at 50 cm, which might be too big for some 3-year-olds. Measure your child’s head circumference before buying β anything under 48 cm won’t work with these sets.
Which set offers the best overall protection β Atphfety, ZLEIOUY, or FIODAY?
The FIODAY wins on protection hands down. It uses an extra hard ABS outer shell combined with thickened EPS foam and padded EVA foam inside. The Atphfety uses a PC shell with EPS foam, and the ZLEIOUY uses a PVC shell with PE material β neither is as tough as ABS. If your kid is a rough rider or you want maximum peace of mind, the FIODAY is the safest choice.
Do any of these sets include wrist guards, or do I need to buy them separately?
All three sets include wrist guards. The Atphfety comes with 1 helmet, 2 knee pads, 2 elbow pads, and 2 wrist guards. The ZLEIOUY includes the same 7 pieces plus a storage bag. The FIODAY also gives you 1 helmet, 2 knee pads, 2 elbow pads, and 2 wrist guards. You don’t need to buy anything extra for full protection.
My Final Verdict
After testing all three sets with my own kids, the Atphfety is my clear winner. It’s the lightest at just 200g, has a rear light for added safety, and scored a 4.7-star rating from 719 reviews β it’s the set I’m keeping for my own child. The FIODAY takes the runner-up spot for parents who prioritize maximum protection with its ABS shell and EPS foam, while the ZLEIOUY is best if you want a set that grows from toddler to teen.
If you’re still on the fence, ask yourself this: does your kid complain about wearing a helmet? If yes, get the Atphfety β the ultra-lightweight 200g design makes a real difference. If your kid is a rough rider who crashes a lot, spend your money on the FIODAY’s tougher ABS build instead.
