Lazer P’Nut & Nut’z

Lazer P’Nut & Nut’z

As one of the world’s oldest helmet manufacturers, Lazer prides themselves on making not just mere helmets, but rather “brain protection” with “an excellent synergy between design, comfort, safety and technology.”  From the outside in, Lazer’s passion for perfection is clearly demonstrated in their P’Nut and Nut’z kids helmets.  The P’Nut (for kids with head circumference 17.88″-19.69″) and the Nut’z (19.69″-21.67″) each come in two different models, the standard non-MIPS and the MIPS.  Helmets that incorporate MIPS (Multi-directional Impact Protection System) are arguably the safest helmets on the market and have shown to decrease brain injury by 30%.  As shown in the video below, the standard helmet is designed to protect the brain from direct impacts (hitting the ground with a strictly downward motion), while the MIPS helmets are engineered to protect against multi-directional impacts (hitting the ground while in a forward, downward motion).

**The P’Nut MIPS is currently not available in the US, but will be shortly.  The Nut’z MIPS is still available at multiple retailers.**

Lazer’s Nut’z and P’Nut helmets are the only kids helmets that offer the MIPS system.  MIPS models run about $20 more than the standard, non-MIPS models.  Besides the MIPS inner cage, the MIPS and non-MIPS models are essentially identical.

Adhering to their higher safety standards, all Nut’z and P’Nut models, are built with in-mold construction.  While the standard in-mold construction increases the durability of the helmet, it also leaves the foam core beneath the helmet exposed.   Lazer saw this as an opportunity for improvement and expanded their plastic shell to fully encompass the exposed foam on the bottom brim of the helmet.  While the plastic shell doesn’t directly increase the safety of the helmet, it does so indirectly by protecting the foam core from damaging punctures and dents.

**The current Nut’z and P’Nutz models have exposed foam on the bottom like the Uvex**

Lazer’s Autofit system also stands out amongst competitors.  Consisting of a tension wire in plastic housing, the system eliminates the need for an adjustment dial by automatically conforming to a child’s head, thereby creating a custom, precise fit with every use.  Seeing that kids and/or parents often don’t take the time to properly adjust a child’s helmet, the Autofit system comes standards in all Nut’z and P’Nut models.  While the Autofit system automatically adjusts the inner plastic housing of the helmet, it is important to note that the first time the helmet is worn, parents will be required to manually adjust the chin straps and side-ear sliders to ensure the straps are properly in place.

In order to work properly, the wire housing must be clipped into the plastic clips on the helmet.  These clips attached the plastic housing of the helmet to the tension system.

In addition to the Autofit system, Lazer’s magnetic buckle allows kids to easily and accurately put on their own helmet (as demonstrated by the three-year-old below).

**The latest model of the Nut’z and P’Nutz helmets do not include a magnetic buckle**

While we generally loved the Autofit system, we did find it problematic on girls with long, loose hair.  During use, the Autofit system seemed slide the helmet up along the loose hair causing the helmet to become out-of-place within minutes.  Once the hair was tied back, the helmet moved slightly, but remained in a safe position on the head.  Due to these findings, the Lazer helmet are only a top pick for boys, not girls.

For young riders with a head circumference (HC) of 17.88″-19.69″, Lazer’s designed their smaller P’Nut model with the reluctant child in mind.  Along with eight bright and colorful design options, nine different Crazy Nutshells are available.  The Nutshell is a plastic cap that snaps on and off the helmet that not only personalizes the helmet, but also protects against rain and wind.  The one complaint our testers had about the Crazy Nutshells were that they were not available on the larger Nut’z model.  In fact, as a word of caution, be sure to measure your child’s head before ordering the helmets, as the P’Nut is rather small and did not fit many of our two and three-year-old testers.

Bottom Line

P’Nut and Nutz MIPS models are hands-down the safest kids helmets on the market.  When purchasing a MIPS model be sure that it is clearly listed as a MIPS model in the product description as the non-MIPS and MIPS models are otherwise identical. The P’Nut MIPS is only available in white (hard to find!) and the the Nut’z MIPS is only available in black, white, “Race Red” and “Race Green”. Compared to other non-MIPS helmets, the standard P’Nut and Nut’z models are top performers as well.  So with exception to the issue with the Autofit system and long hair, if you are looking for a durable, worry-free helmet, the Nut’z and P’Nutz models are a top pick.

        General helmet question, although we have the Lazer Nut’z… How much should the helmet be able to move when placed on head and buckled? For example, if I move the helmet towards back of head, should forehead be able to become fully exposed?

        • No, the helmet should sit on top of the head and not slide back, but it is a common problem with most helmets that is hard to prevent due to the various shapes of kids heads. The best way to prevent sliding back is to make sure the straps are properly tightened and they are secured under the ear with the slider, making a tight triangle (no flaps in the straps).

        I’m getting ready to purchase a balance bike for my almost 2 year old son. He currently has a Lazer BOB helmet for our bike trailer. Would this helmet be suitable for riding his balance bike? When I click on Lazer BOB in the comparison chart it just takes me directly to Amazon and not your review. If I do need to buy a new helmet for riding his balance bike I’d like it to also be suitable for riding in the bike trailer. I was thinking the Lazer P’Nut or Giro Scamp. I would probably go with MIPS. Any other helmet suggestions if the Lazer BOB is not suitable for bike riding? How many summers (what age) can we expect to use the next helmet we need to purchase? Thanks!

        The Uvex looked like a nice option too, but his HC is only 18.5″. I read a review somewhere that you wrote recommending the Joovy Noodle. I found it on sale at tikes bikes for only $25 plus a 10% discount and no sales tax or shipping. If we do need to buy a new helmet and it’s only going to be used this one summer I’d like a good helmet with a lower price tag.

        • The Lazer BOB will work just fine for his balance bikes. In terms of safety regulations, there isn’t a difference for helmets used in trailers or on bikes. The BOB is more suitable for trailers because the rear of the helmet is flat, not because it meets a different standard for bike helmets. For now, I would stick to the BOB and then once he outgrows it, remeasure him and see which one works with his head size.

            Awesome! Thank you! I’m going to wait until his HC is big enough for the next size up and then probably buy the Lazer Nut’z with MIPS. How will I know if he has outgrown the BOB? I know it goes up to 52cm HC. I read reviews and most said their child outgrew it between 18 months and 2 years. He’s in the lower percentiles for HC so I’m assuming those kids have a larger HC. I know I do need to make adjustments because the front is pushed up when we get done riding. He does love wearing it though:)

            • When the helmet gets too tight to easily slide over his head or when there is more than about a 2″ gap between the top of hear and the bottom of the helmet, then the helmet is too small and it’s time to upgrade. Of course, with kids, when they start complaining about it, that they is always a sign as well.

        I never thought my almost 2 year old son had a big head. He was always tall for his age but slim (about 36 in, 27lbs). I just measured his head and I’m getting 49.2cm. Would he be too small for the Nut’z? I feel like he may outgrow the P’Nut (super cute dragon) too quickly. Thoughts? I really like the features of both (MIPS, vents, and auto adjust).

        • I agree that he will probably outgrow it too quickly. My son loved it wore it for as long as possible, but at around 51cm, it hurt him to wear it, so we had to move on. I would go for the Scamp in a S. It also comes with MIPS and is easy to adjust,

        I just bought the Nutz for my son who measures right at 50 cm, and it almost seems too loose. I also can’t seem to get the chin strap to be short enough so it’s tight under his chin and our helmet has the magnetic closure but has exposed foam. My LBS special ordered it, so I don’t think it’s an older model that’s been sitting around and it’s a current color (yellow skulls) so I’m not sure what’s going on.

        • Wow, thanks for bringing that to my attention. I wasn’t aware that they had made changes, I will be sure to make note of the exposed foam in the review. I am also surprised that it doesn’t fit a 50cm head as on Lazer’s site it still lists the Nutz with a 50-56cm measurement. Ugh, sorry, I can image how frustrated you are, especially considering your special ordered it. For the chin strap, adjusting it can be a challenge, but it should be able to adjust. To get it tighter you will have to make the looped end of the buckle shorter. The chin strap is one long continuous strap, so you can make the one side shorter. You will have to snake it through the back of the helmet where the strap is looped through a small strap to keep the strap in place.

        My son is 3y and his hc is 52cm
        Will you recommend lazer nut’z or giro raze?

        • I prefer the Nut’z with it’s autofit system, but we have used both helmets extensively and they are both great!
