Midlayer Ignite Drill trainingshirt from Nike.
The shirt has rib neck and is well isolated to keep you warm both on and off the pitch. In addition, it has a 1/4 zip. Furthermore, the shirt is made of the unique Dri-FIT material, which wicks sweat from your body and keeps your skin cool.
This is a 'midlayer' shirt - a shirt meant to be worn on top of a base layer, and under, for example, a jacket.
The nice Ignite Drill shirt also comes with a nice thumb-hole feature, so you can even keep your hand warm.
Made from 100% Dri-FIT polyester.
