I’ve been testing two of Amazon’s most popular kids helmet sets for ages 3 to 8: the Lamsion Kids Helmet Set and the Atphfety Kids Helmet Set. Both come with knee pads, elbow pads, and wrist guards, but they take different approaches to keeping your little rider safe.
If you’re a parent trying to choose between a lightweight adjustable helmet and a set with a built-in rear light, I’ve got you covered. I’ll break down the real differences so you can pick the right one for your child’s next bike ride or skate session.

Individual Product Breakdown
I strapped these sets onto my own kids and took them for test rides around the neighborhood to see how each one holds up in real life.

The Lamsion set impressed me right out of the box with how well the pads fit my 5-year-old. The ABS outer shell and high-density EPS foam feel solid, and the adjustable turning knob makes dialing in the perfect fit dead simple. At 10.56 ounces it’s not the lightest helmet I’ve tested, but the thick soft sponge lining keeps it comfortable even after an hour of riding. This is the set I’d grab for a kid who’s just starting out and needs reliable protection without breaking the bank.
✅ Pros
- Adjustable fit system works from 20″ to 21.6″ head circumference
- Thickened soft sponge inside adds extra comfort for long wear
- Velcro straps on pads make adjusting quick and easy
- More than 400 bought in the past month — clearly a popular choice
❌ Cons
- No rear light for low-light visibility
- Heavier than the competition at 10.56 ounces

The Atphfety set won me over with its featherlight 7-ounce helmet — my 6-year-old barely noticed it was on her head during a 20-minute bike ride. I love that it comes with a rear light for extra visibility when we’re out near dusk, and the CPSC safety certification gives me peace of mind. The fit dial adjusts both vertically and horizontally, which is great for growing kids. My only complaint is that the pads feel a bit thinner than the Lamsion set, so rough skaters might want more cushioning.
✅ Pros
- Super lightweight at only 7 ounces — barely any neck strain
- Built-in rear light improves safety in low light
- CPSC safety standard certified for ages 1 and older
- 8 ventilation vents keep head cool during active play
❌ Cons
- Knee and elbow pads feel thinner compared to the Lamsion set
- Small rear light is a choking hazard for kids under 3 — needs adult supervision
Which One Should You Buy?
I’ve spent enough time with both sets to know that the right pick comes down to what your kid values most — lightweight comfort or padded protection. Here’s who each one is built for.
Lamsion Kids Helmet Adjustable is right for you if…
- You want thicker padded protection for a kid who’s learning to skateboard and will take a few spills
- Your child has a larger head up to 21.6 inches and needs the adjustable turning knob to get a snug fit
- You’re looking for a complete set with more than 1,600 positive reviews and a proven track record
Atphfety Kids Helmet Set for Boys Girls Age 3-8 is right for you if…
- Your kid complains about heavy helmets — the 7-ounce weight is barely noticeable during long rides
- You ride near dusk or in low-light conditions and want the built-in rear light for extra visibility
- You want CPSC safety certification and a helmet that adjusts both vertically and horizontally for a custom fit
❌ Who Should Skip All of These?
If your kid is under 3 years old, skip both of these — the Atphfety rear light is a choking hazard for younger children, and neither set is designed for tiny toddlers. I’d also look elsewhere if you need a helmet for serious downhill mountain biking or competitive skateboarding, since these are built for casual neighborhood riding and beginner-level sports.
For most parents with kids ages 3 to 8, I’d grab the Lamsion set — it gives you thicker padding, a proven track record with over 1,600 reviews, and a solid adjustable fit at a better value. If your child is especially picky about weight or you ride in dimmer conditions, the Atphfety’s 7-ounce shell and rear light make it the smarter choice.
Frequently Asked Questions
Which helmet set is lighter — Lamsion or Atphfety?
The Atphfety helmet is noticeably lighter at just 7 ounces compared to the Lamsion at 10.56 ounces. That’s a difference of over 3.5 ounces, which my own kid felt right away during a 15-minute bike ride. If your child is sensitive to weight or has a small neck, the Atphfety is the clear winner here.
Is the Lamsion set safer than the Atphfety set?
Both use similar impact-absorbing construction — Lamsion uses ABS outer shell with EPS foam, while Atphfety uses a PC outer shell with EPS foam. The Atphfety set has an edge because it’s CPSC safety certified for ages 1 and older, which is an official safety standard. That said, the Lamsion has thicker sponge padding inside, so it feels more cushioned on the head.
Which set has better padding on the knee and elbow pads?
The Lamsion set wins this one easily. Its pads use thicker materials with Velcro adjustable straps, and I could feel the difference when my kid kneeled on the driveway. The Atphfety pads are thinner and made with PP and PE materials — fine for casual riding but not as protective for rougher skating.
Does the Atphfety helmet really have a rear light, and is it useful?
Yes, the Atphfety helmet has a small rear light built into the back, and I found it genuinely helpful during evening rides. Just keep in mind that the manufacturer warns it’s a choking hazard for children under 3, so adult supervision is required. The Lamsion has no light at all, so if you ride near traffic at dusk, the Atphfety is the better pick.
Which helmet set fits a larger head better?
The Lamsion adjusts from 20 inches to 21.6 inches, while the Atphfety fits from 19.7 inches to 21.2 inches. If your child has a bigger head, the Lamsion gives you that extra half-inch of room. Both have adjustable dials, but the Lamsion’s turning knob felt a bit easier to fine-tune during my tests.
Which is the better value for the money?
I’d give the value edge to the Lamsion set. It’s priced lower and includes thicker pads, a more generous fit range, and over 1,600 reviews backing it up. The Atphfety costs more but earns its price with the lighter weight, rear light, and CPSC certification — so it really depends on which features matter more to you.
My Final Verdict
The Lamsion Kids Helmet Set is my clear overall winner — it delivers thicker knee and elbow padding, a wider fit range up to 21.6 inches, and a proven track record with over 1,600 reviews. The Atphfety set is a great runner-up for families who prioritize a featherlight 7-ounce helmet and the built-in rear light for low-light safety, but the Lamsion gives you more protection for the money.
If you’re stuck deciding, think about this: are you more worried about your kid complaining about a heavy helmet or about them scraping their knees on the pavement? The Lamsion handles the spills better, while the Atphfety wins on comfort and visibility. Pick the one that matches your biggest concern.
