Rukka Maakala is a simple yet functional long-sleeved shirt with fixed hood and half zip. The hoody is great on its own, but it is also well suited to be worn as a midlayer under a jacket. The 2-way-stretch fabric doesn't restrict movements. There is a handy key pocket on the back as well.
No irritating side seams.
100% Polyester
The 2-way stretch material increases the freedom of movement.
