### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very good
  

*by X***Z on Reviewed in the United States on November 20, 2023*

Feels solid, as true downhill helmet, is lightweight and vented enough I can use it in SoCal.Can even drink in it if bottle allows.Perfect integration with SMITH goggles, zero nose pressure and wide view, adjustable visor.Fits true to size, leaves enough space in front of the chin.Downsides are:* noisy MIPS liner. It constantly makes sounds, hopefully it will get quiet after it settles a bit.* d-ring strap buckle. It’s the most secure out there but probably an overkill for enduro helmet. Not a big problem though as I don’t really get an urge to remove it as often as typical downhill helmet.Both downsides are not enough to take 1 star off though.
