Castelli FEROCE MIDWEIGHT LS

Don’t think of it as a long sleeve base layer. Think of it as a short sleeve base layer with arm warmers attached. It’s made to be used with a short sleeve jersey by making the sleeves in our heaviest weight seamless construction, the body is medium weight, and we use a lighter weight fabric under the straps of your bibshorts. You get perfect temperature equilibrium. And when things heat up? Just push the sleeves up since the ultra stretchy construction makes it easy and comfortable.
