just right

  • Familiarity: I've put it through the wringer

my favorite skull cap. not to thick, my helmet still fits right. Warm enough for the lower temps I ride in. definitely recommended.

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 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.
