Why We Like The Wilder Jr MIPS Helmet

Young riders are resilient with go-getter attitudes that can sometimes lead them into trouble, and that's why we fit them with the Wilder Jr MIPS Helmet for their rides. This helmet, from Smith, combines the improved angle impact protection of MIPS with a lightweight, ventilated design that is just like our helmets as adults. A total of 21 fixed vents keep things airy and light, and the VaporFit dial system finds an optimal fit every time. The Wilder Jr has everything they need to bomb down their favorite trails with purpose and ease.

Saved my kid's melon

Bought this helmet for my 4 y/o son when we got him a new bike. Within a month, he lost lost control going down a slight hill, causing a significant crash. He hit the back of his head on the pavement. The helmet covers the back of the head and protected him from a serious injury. The shell was damaged and the foam cracked through, showing how hard of a hit it was, but my son was completely unharmed. After seeing how well it protected him, I did not hesitate ordering the same helmet to replace it! Aside from the crash, you are able to adjust the straps to get them fitted properly and you can easily dial in the fit, which also contributes to the safety.

Great helmet

Love the fit on my girls. Love that I can see them easy when they are up in front because it’s such a great color pink.

Perfect upgrade for my 3 year old

I got those to replace my sons first helmet. This one looks way better and has MIPS which is crucial for him being on trails. Fits great with the boa style adjustment around the inside of the helmet. Will be able to grow with him for a good bit.
