Sizing Information for Castelli Clothing:
SławGreat cap good fit
DavidJI wear this cap, under my MED (59cm) Bell helmet, and it does not leave a mark on my forehead. Beautiful Fall/Winter cap. No loose threads, straight stitching & good fit. I wish I bought more than two!
Mr JohnsonGreat cap for under my helmet. Very soft and comfortable
RussellGood quality gear as you'd expect from Castelli. The flaps covering the ears are great. I've worn it on the odd occasion when I've not worn a helmet and it's been 5-10 degrees. The flap is handy against the low winter son and I don't find it makes my head sweaty. I've not tried it under my helmet yet, but it will definitely fit. It comes in one size only and it is a fraction too large for me to be snug. I'm a 58cm in normal hat sizes.
StephenIt's a good Spring Summer Autumn cap. Useful to wear under a helmet giving a peak against low sun or against rain. The fold down earflap almost covers my ears, it doesn't fully cover my ear lobes.
(For colder weather I use a hood, or my merino base layer with a built in balaclava that fully covers my ears)
Mr RycroftExcellent bit of kit. Especially in the current weather
