When your young rider is dedicated to the dirt, you need gear that keeps pace with their skill set. The Smith Wilder Jr. mountain bike helmet combines the enhanced angle impact protection of MIPS® with a lightweight, ventilated design just like our adult helmets. 21 fixed vents keep the air flowing as kids bomb down their favorite trails. Our VaporFit™ dial system adjusts around the head with the turn of a dial to get the right fit every time. There’s a built-in visor to cut glare and integrated sunglasses storage, so kids can stow their glasses just like mom or dad.Protection:- Lightweight in-mold construction- MIPS® Brain Protection System reduces rotational forces caused by angled impacts to the headFit / Integration:- VaporFit™ dial adjustment system offers 270-degree fit adjustment with the turn of a dial- Designed for ultimate integration with Smith performance eyewear and goggles for maximum comfort,venting and storage convenience- AirEvac™ ventilation system integrates with Smith goggles and eyewear for fog-free lensesFeatures:- 20 fixed vents for consistent airflow- Integrated visor- Performance comfort lining- Lightweight, low-bulk single layer webbingSpecifications:- Weight: (Size XS, MIPS®): 10oz / 270gTechnology:MIPS®:Mips® is a brain protection system – engineered to add protection to helmets.- The MIPS® Brain Protection System (BPS) is found inside the helmet, generally between the comfort padding and the EPS (a high-quality foam used to reduce energy). For certain impacts, the MIPS® BPS can reduce harmful forces transmitted to the brain. MIPS® stands for Multi-directional Impact Protection System.AirEvac:- Precise fit: Ultimate integration starts with the precise fit of the Smith goggle and helmet. Our helmets are designed to match the curvature of the goggle frame, eliminating ”gaper gap” and allowing precise alignment between the helmet AirEvac and the goggle venting systems.- Maximum airflow: Goggles fog when standard helmets trap warm, moist air in the goggle chamber. Smith’s AirEvac ventilation systems generate maximum airflow and pull warm, fog-causing air out of the goggle. The warm air is allowed to exhaust out of the top of the goggle and begin its path through the helmet’s AirEvac system.- Rear exhaust ventilation: The warm air that originally built up in the goggle has been forced out via the AirEvac ventilation system, has traveled through the AirEvac 2 EPS vent channels, and is now being exhausted at the furthest distance possible from the goggle. Ultimate integration between goggle and helmet from start to finish.- Maximize ventilation: The well ventilated, KoroydN panels ensure consistent, engineered airflow whether riding or stationary. In addition, the Smith helmets features internal air channels that combine with open intake and exhaust ports to maximize ventilation.
