Excellent Temperature Regulation

  • Familiarity: I've used it several times

So far I've been very impressed by this base layer. I've worn it in temperatures varying from 40 - 65 degrees and love it. It does a fantastic job regulating temperature and keeping you dry, plus it has an incredibly soft feel. It pairs great with my Transparente Long Sleeve Jersey, and just about any short sleeve jersey I have. Despite it being a bit pricey for a base layer, I love all things Castelli and figured it was worth a try. It's definitely worth it.
