Lazer P Nut and Lazer Nutz Helmet Review


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.

MIPS Safety System

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 Lazer’s video, 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).  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.

Construction & Durability

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. **UPDATE: The plastic shell on the current models of the P’Nut and Nut’z helmets does NOT cover the lower portion of the helmet.  Lazer currently does not plan on adding this feature back into the helmet.  The only helmet that we know of that currently offers this feature is the Troy Lee Design A1 Youth helmet.

Autofit Adjustment System

Lazer’s Autofit system also stands out amongst competitors.  Consisting of a tension wire in a 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.

Lazer’s Autofit Adjustment System

While we generally loved the Autofit system, we did find it problematic on girls with long, loose hair.  During use, the Autofit system seemed to 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 is only a top pick for boys, not girls.

Bottom Line

P’Nut and Nutz MIPS models are one of the safest 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.  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.
