great cap

  • Familiarity: I've used it several times

thin enough to easily fit under my helmet, which is close to being too small for me, and warm enough to keep me comfortable in the 30 F range. Recommended.

My FAV!

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

My go to cycling hat, of which I have many! The fabric is really good quality and it fits great, even on my large head(female)! The weight is great for all temperatures. I put it on when I start which is usually after a swim and I'm cold, but when the temp's warm up, it is tis a great cap Really pleased with this purchase

Great skulls cap

Minimal, fits snug, and warm enough. Great addition to cold weather options!!!

True Skull Cap

  • Familiarity: I've used it several times

Fits under the helmet, and just warm enough to take the edge off. A lot of other hats say they're "skull caps" but are too bulky for under-helmet wear. This one is great.
