Pearl IzumiThermal Run Hat


Pearl Izumi's Thermal Run Hat is so versatile that we've only found one limitation: it's gotta be cold outside. And by "cold," we mean around 50 degrees Fahrenheit for casual use and below 40 for cycling and cross-training. It's also slightly bulkier with less forgiving stretch than Pearl's Thermal Skull Cap, but it still fits neatly under a helmet when you let the fit dial out.

The key to the Thermal Run Hat's versatility is the Thermal Dry material. Its moisture-management and insulating properties mean the hat will accompany you on winter outings ranging from logging base miles to shoveling the walks.

    I have a normal size head and this cap was super snug. Would only get if you have a small head.
