Nike Men's 3-1 Tech Pack Running Jacket.

Uniquely patterned and uniquely worn. Very lightweight for a great pack stashing option.   Water Repellant.  Size Large. Standard Fit.  New with tags.  Layering up for cool runs in the spring and fall can be tricky—you don't want to wear too much and get all stuffy, but you don't want to be fighting the chill either. Able to zip out into just a vest when you start to heat up too much, the Nike Tech PCK Transform HD Jacket provides a quick and easy way to regulate your temperature on cool weather runs. The wind and water resistant fabric fights off blustery breezes and light rain, while a fixed hood delivers snug coverage from the elements thanks to its over-the-chin fit. But when the wind dies down, the temperature warm ups, or you start to really pick up the pace you're going to want to ventilate, and this jacket provides more in the way of cooling down than opening up the main zipper a bit. You can simply unzip the jacket's overlays and in an instant you'll be running in just a vest. You'll be nice and cool as you pick up the tempo, and with the rest of the jacket stuffed into a convenient back pocket you'll still be able to run hassle free.
