Description

Warm up.

When the mornings turn brisk, the trees start to show off their colors, and fat bike season approaches, 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 profiles to add a dose of cozy comfort to your cold weather rides.

The Timberwolf's 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 features Giro's In Form Fit system, which 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 commuting and fat bikepacking
  • In-mold construction increases structural integrity
  • Brushed fleece lining and removable ear pads provide warmth
  • Adjustable ventilation tailors airflow to the weather
  • Front Stack Ventilation reduces goggle fogging

Designed primarily for skiers, but happy

  • Familiarity: I've used it several times

Very good quality, good fit. Keeps the melon warm in sub-zero temperatures. I commute 30 miles in Wyoming to my job and typically that's close to a couple hours in 20 degree temps. I have a 23 and 1/2 inch head and went with the large. Happy with my choice as I can still sneak a balaclava beneath it. And yet there's no movement without the extra layer. if you are only used to cycling helmets this does add a bit of unexpected weight. But with that comes a little extra feeling of security and safety. My only knocks on it are that at the temperatures you would want it you'll likely be wearing ski goggles. Good news: The helmet was designed to be used with ski goggles as there's a clip for the strap in the back and channels on the sides. However if your head is down and you're looking up at the road the goggle/helmet combination will probably interfere with a little bit of your vision. As with most winter cycling situations you're probably a bit more upright anyway so it may not be an issue for you. Secondly as you're craning your neck the adjustable helmet strap in the back can put a slight bit of pressure on your neck. While that's not a deal-breaker it's obvious that the helmet comes from the ski industry where neck craning is not part of the game. Overall: Glad I added this to my winter kit.

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.
