A classic and popular original, the Icebreaker Women's BodyFit260 Tech Top is a mid-weight layer that sets the standard in high quality New Zealand merino wool natural fiber. Not the wool of the past, the fine fiber and itchless merino wool insulates when wet, is odor-free (unlike synthetics), is incredibly breathable, and offers excellent warmth at half the bulk. This top is perfect as a winter base layer when skiing, snowshoeing, or alone during a cool weather aerobic activity. The top features a three-way collar (zipped up, rolled down, open) for venting and warmth versatility, thumb loops to keep the sleeves in place and cover wrist gap, drop tail for covering waist gap, and side panels for outstanding mobility. Arguably, the warmest and most breathable performance base layer in the world, the brilliant Women's BodyFit260 Tech Top is designed for cold conditions in a flattering, slim close-to-body, feminine fit.
