CastelliDifesa 2 Cap(Return to Product Page)

With the exception of some winter gloves, I've found Castelli apparel consistently sized way too small and ill-fitting. For that reason I was skeptical of the "one-size-fits-all" description for this cap, but I gave it a try with the hope it would provide lightweight and breathable head cover under my helmet in cold and damp weather. It is well-constructed with quality materials, I'll give that. But as with so many Castelli pieces of kit, this only fits smaller heads because the trimming along the hem has no elasticity, no stretch whatever. The circumference of my skull is ~59cm, which straddles medium and large helmet sizes, but this cap barely fits and is so tight that it gives me a headache after a while. How is this "one-size-fits-all" if there is no stretch to accommodate different head sizes? Unless you have a smaller pate, save your money. It won't fit.

The shell stops the wind and rain getting to your head, ear flaps for when you need them have a micro fleece.

Over all very warm without lots of bulk below the helmet.

If you don't like the sun in your eyes or frozen ears this is a neat little cap. The earflap can be tucked under the cap to hide it, but if your head is about the size of mine 58-59cm you might find this a little too tight. Castelli make great gear. This cap is just what I had in mind and BTD had a nifty price on it. Thanks!

Wind was blowing...Snow coming down. Great conditions to road ride test with the new Castelli cap. Perfect....Kept my ears warm, brim kept some flurries outta my face. Cap is Windstopper, the ear flap is not. But it's thin enough that you can wear under your helmet, and the ear flap is thick enough that it works keeping your ears warm, plus you gotta be able to hear, right? It's a little pricey but Castelli stuff is usually top quality. If its brutal cold (Hello Minnesota) this thing may not be enough but for anything in the 10s to 30s it's my new favorite headwear.

I have a very small head... it is still a snug fit.

Overall fit was a bit too tight for me. I will keep it and use it but it was not as comfortable as I had hoped. Also, the covering over the ears could have been a little bit longer.

So, I'm nearly bald. That makes keeping my head warm more of a challenge riding bicycle when the temps are in the 20's -30's.and the wind is gusting to 30mph. I've tried several options and I'm either too hot or too cold. The Castelli Difesa 2 Cap does have a down side, and that's it's size. It fits small at first. I remedied this by stretching the cap out quite aggressively without damaging it. This worked! It's now even comfortable with a thin skull cap underneath. As a reference, my normal hat size is 6-7/8, to 7. I'm glad I bought this cap. It makes all the difference.

Love this, fits great not bulky and really does what it says it will do. Far warmer than expected and because it sheds rather than absorbs moisture, it stays warmer than even a wool cap. Wearing it on every ride this winter. Brim keeps its shape and yep, keeps at least some of the rain off glasses.
