Warm up.

When the mornings turn brisk and trees start to show off their colors, it's time to start thinking about finding a helmet that will keep you warmer than the super-vented summer fare. Giro's Timberwolf Helmet is designed with chilly temperatures in mind and borrows inspiration from snow helmet design to add a dose of cozy comfort to your cold weather rides. Its Thermostat Control ventilation system lets you easily adjust how much air gets through to maintain your microclimate, while a brushed fleece liner and removable ear pads provide much appreciated warmth and protection from the elements. The Timberwolf utilizes Giro' In Form Fit system utilizes a quick-turning dial for up to six centimeters of fit adjustment and a vertical turning option that lets you adjust fore-aft positioning, even on the fly.

  • A cold-weather helmet for commute and trail
  • Streamlined, in-mold construction
  • Brushed fleece lining and removable ear pads provide warmth
  • Thermostat Control lets you adjust ventilation
  • Front Stack Ventilation reduces goggle fogging

Excellent winter helmet

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

This helmet is super comfy on my bald head. Fit is great and the closable vent is a nice touch for cold weather. Can be used for road, mountain or winter sports. Very versatile.
