The K2 Route Helmet is a lightweight and breathable helmet that receives some widespread complaints. There are some construction issues, goggles are not compatible with the clips, the snow and rain cover isn’t the best, the outer shell might dent, and the internal padding isn’t amazing. Even though the ventilation system works well, the vents aid in temperature regulation, and the BOA system allows for adjustments, the construction issues have resulted in numerous negative reviews.
