Get ready to experience one of the lightest backcountry helmets with the Envi Spherical®.
Heading into the backcountry is no joke, and neither are the performance features of the Envi Spherical helmet. But you don't have to go off the grid to reap all of its benefits. You'll notice its extremely lightweight construction allows you to make powdery turns and then tour back to the top without being weighed down. When you're feeling the burn and things start to heat up, easily control your temperature with the Thermostat Control and Stack Ventilation. The Envi also features Mips Spherical technology, which aids in the reduction of rotational energy during certain impacts for an additional level of confidence. Plus, you'll stay extra comfortable thanks to its Plush Max fleece that dries quickly and provides a super-soft feel. Buckle up and drop in in the Envi Spherical!
  • SPHERICAL TECHNOLOGY — Spherical Technology's Ball-and-Socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.
  • IN FORM 2 FIT SYSTEM — The In Form 2 Fit System is lighter and lower-profile than the original, and easier to dial in a custom fit in seconds - even with gloves on. An improved dial design provides up to 6cm of adjustment plus enhanced stability.
  • FIDLOCK MAGNETIC BUCKLE CLOSURE — The pinch-free, one-handed Fidlock® magnetic snap helmet buckle combines the advantages of two fastening concepts in a completely new way: Strong magnets make it easy to open and close, while a secure snap functionality ensures a continuous locking force.
  • SEAMLESS COMPATIBILITY — For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function.
  • VERTICAL TUNING — Accommodates different goggles and head shapes for a custom fit free of gaper gap
  • THERMOSTAT CONTROL — Thermostat Control Adjustable Venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
  • HARDSHELL WITH IN-MOLD HARDBODY™ LOWER WRAP — The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight.

Bike Helmet Size Guide

How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
