The temperature outside may drop, but your body temperature stays toasty warm when you're wearing Pearl Izumi's P.R.O. Bib Tights. The cold-weather lowers feature P.R.O. Thermal fabric for stellar insulation and comfort, and they're encased in AmFIB Softshell material for extra wind and water protection in all the right places. Up top, the Direct-Vent mesh shoulder straps provide excellent ventilation so you stay dry all ride long. Flatlock and double-needle seams provide even more comfort, while reflective elements throughout the bibs provide low-light visibility. Top it off with a fast-drying Minerale upper and you've got all-day bibs with winter weather on their mind.
