C3 Gore Windstopper Helmet Cap

Your helmet is great in the summer, with plenty of vents to keep air moving to keep your head cool. However, when temperatures start to drop, you need to add the Gore Wear C3 Gore Winstopper Helmet Cap to your combination to keep yourself warm. This hat features a Gore Windstopper membrane to defend your head against heat loss without trapping air in—keeping you from overheating. The synthetic interior efficiently wicks away moisture, so no matter how hard you pedal you can expect to stay dry, while an elastic binding keeps the stretchy fabric from moving around.
  • Helmet-friendly cap for cool-weather cycling
  • Gore Windstopper protects your head from wind
  • Stretchy fabric provides a comfortable fit
  • Polyester lining manages moisture
  • Elastic binding secures the placement

I purchased Gore's helmet cap and also their thermal beanie for comparison. The fit of the helmet cap was much better for me, with respect to the ear coverage -- the helmet cap covered my ears very well, while the thermal beanie just barely covered them. I returned the thermal beanie because I am sure my ear lobes would have become uncovered pretty quickly once riding! I wore the helmet cap out on a 45-degree day and my ears and head were nice and warm, and the fit felt great. The Cons of the helmet cap: (1) I wish it had slits for glasses like the thermal beanie. (2) The fabric near the ears is noticeably louder in the helmet cap vs. the thermal beanie. It rustles quite a bit...but once I was out riding I didn't notice it. (3) I had a line across my forehead for the rest of the day, there's some serious elastic holding it in place! But I think this is the cases with most caps like this.

A quick comment on the size...I bought a Large, expecting it to run smaller than sized (which is typical of every other Gore item my wife or I have). But it actually runs a truer to size. For reference, the circumference of my head is 23 inches (just above the eybrows, where this cap sits) and the Large fits well. It appears that the crown is not wind-proof; only the part around the forehead and ears have the typical Gore wind block feel. I haven't used it yet, but I fully expect it to perform as expected.


Is the entire hat Windproof? Some cycling hats have just the front in Windproof material so I wanted to double check.


Could you provide a precise range from each size (like helmets)?


This is a great product, per usual from Gore. But poorly described. Just to clarify: This thermal cap goes on your **head**! This is not a "helmet" cover (like the excellent helmet covers from Gore, Louis Garneau, or Sugoi).
