100% Altis Mountain Bike Helmet
The 100% Altis Mountain Bike Helmet is a trail-focused half-shell helmet built around expanded coverage, airflow, and the Smartshock® 11-point rotational protection system. It is made for mountain bike riders who want a lightweight helmet with adjustable fit and real ventilation.
Why We Like It
The Altis gives riders a good mix of coverage and comfort without feeling overbuilt. The 14 vents, washable liner, ratcheting fit system, and adjustable visor are all practical details for regular trail riding.
Why It Works For You
Use it for mountain bike rides where you want better coverage than a basic road-style lid while still keeping airflow and comfort in the mix. The visor and goggle-stowage-friendly design also make sense for riders who switch between glasses and goggles.
