The Rittervest™ is thoughtfully constructed with superfine Alpaca and Merino sheep wool. Both of these natural fibers exhibit superior thermoregulating properties, which means that they keep you warm but are also extremely breathable, allowing your body to adapt to climates quickly and comfortably. You’ll basically be like a baby alpaca in the Andes, able to handle temps from -30F to 100F. We don’t know if your office or work commute regularly experiences that kind of temperature swing, but if it does you’ll be golden.
