The half zip of your fall and winter dreams. We've combined Classic Lux, Polartec® Alpha Insulation and our Katron Woven shell fabric to produce a style that is protective and weather-ready, yet still very light weight. This is the ideal half zip for cool temps, wind, and even snow. As you sweat, the design allows breathability. But also, the shell fabric provides protection from the weather, keeping your core warm and dry, where you need it most.

Great item!

True to size, beautiful color, great texture

great for 40 degree running

I just wore this for the first time and was so excited I had to come and write a review! I wore it with a short-sleeved shirt underneath and it was perfect for 40 degree running. I didn't feel hot or cold during the run, just perfect. It's also a nice looking top and quality material.

Versatile mid-layer for winter

This is a great top for colder weather running - either alone, or as a mid-layer for super cold days. I love the chest pockets for small items. Sometimes Oiselle long sleeves are too long in the arms for me, but this fits just right. The high collar is nice for blocking wind, too!

My new go-to layer

This is quickly becoming my new go-to fall and winter running layer. The Lux fabric makes it incredibly cozy, the pockets are incredibly functional, and the insulation helps break the wind and keep my boobs warm (they tend to get cold and ache when not protected in the winter). I want to wear it all day it's so cozy.
