The identical Windstopper technology to what you get in the long sleeve version of this base layer. The short sleeves are a bit more ideal for gusty days that aren't just outlandishly cold.

Its Stretch Shield System is built on a 4-way stretch, windproof, breathable Windstopper panel. Windstopper is strategically placed on the chest to protect you where you need it most. Since the Windstopper is applied to Craft's proZero base layer so you can still get top-notch moisture transfer from your skin. Recommended for windy days 55 degrees and below, when the gusts make it feel a good bit colder. Available in sizes Small-XXL.
