Cool spring mornings are no match for this ultra-lightweight sportop with superior breath-ability. Large, open hole performance mesh fabric offers just enough warmth to get you started on your run, then Ventlite mesh panels let off steam the rest of the way. Long, lean fit with slight drop tail for coverage. Zippered back storage pocket stows your essentials. Envelope style thumb-holes keep sleeves down and hands warm, but stay covered when not in use. Front and back reflective elements keep you visible in low light.
