The Pace Midlayer is stretchy and warm. It is very comfortable in situations where a short-sleeved or thin exercise shirt is not enough. The material works well both when worn directly on the skin or over a technical or merino wool base layer shirt. When the weather demands, throw on a weather-resistant jacket and go for it! The sleeves have openings for a sports watch screen - this way, the watch can hunker down exactly where it needs to, to provide the best heart rate data, while your wrists stay warm with the extended part of the cuff. The openings can just as well be used as thumbholes. - Normal fit - Stretchy, air-trapping, and moisture-wicking fabric - Fixed hood - Sleeve pocket for, e.g., a compact phone - Proper reflective stripes
