My go to Base in the Mountains
I received one of these nice base layer this winter. I was traveling in Portland, Atlanta, Tucson, and Sun Valley. Surprisingly I used them all of these places. It works great under lots of layer in the snow in SV, or cold windchill on the rare mornings in Tucson. It is great to have in the arsenal. This is ideal for cold racing, when you want to stay just warm enough but it needs to breath. The front shield really keeps the chest and body warm but leaves the back open for sweat to evaporate.
leave the vest at home, zip your RealCyclist jersey up and just ride, no more fiddling with extra tops.
(did a guy from florida really review this before me??)
