What Our Gearhead(R) Experts Are Saying:"I started a run at dawn when it was cold enough to see my breath, and by mile three I was working hard enough to sweat through anything else I own. This stayed dry against my skin the whole time. The DRICOMFORT fabric pulled moisture off fast enough that I never hit that clammy, overheated stretch that usually makes me unzip everything by mile two."Cool mornings that turn into hard efforts need a layer that keeps pace with the body's temperature instead of fighting it. The Rebecca 1/2-Zip Grid Fleece Pullover from Halfdays does that with DRICOMFORT GEO 365 fabric, which pulls heat and moisture off the skin as effort builds, so the grid fleece underneath keeps insulating instead of turning damp and heavy. The 4-way stretch construction moves with a full stride or a deep reach, and the adjustable hem locks out cold air on a windy start without restricting anything once the pace picks up. This is the pullover for early sessions that don't stay cold for long.
