The Callisto is the ultimate choice for riders seeking a fusion of top-tier performance, sophisticated style, and elite safety. Designed with a slightly rounder shell shape to accommodate a wide range of riders, this lightweight ABS helmet features triple ventilation and a luxurious adjustable leather harness for all-day comfort in the saddle.

  • Triple Safety-Certified: Tested to the industry's highest standards, including PAS 015:2011, ASTM F1163-23, and EN 1384 2023 for total peace of mind.
  • Evoke Liner System: Utilizes a removable, moisture-wicking padded liner that allows for a precision fit and easy hygiene—simply swap liners to keep your helmet fresh.
  • Superior Ventilation & Fit: Features a triple-vented lightweight shell and an adjustable 4-point leather harness for maximum airflow and a secure, soft-touch feel.

Liner Compatibility & Thickness Chart

We all know head shapes aren't one-size-fits-all. That's why Evoke created specialized custom-thickness liners to solve the most common helmet fit issues.

  • Got a headache? If you're right on the edge of a size bracket (like 55cm or 58cm), swap your standard liner for the Custom 2mm option. It trims back the internal bulk just enough to give you a comfortable, pinch-free fit without stepping up to a loose shell.

  • Helmet sliding or rocking? If you have a finer or more oval head shape, standard padding can leave gaps. The Custom 12mm and 15mm liners add plush, targeted thickness to firmly anchor the helmet in place.
