It's Koi Because...
It's a koiski necessity. This round neck, long-sleeved shirt in soft blue by Falke, keeps you incredibly warm in very cold conditions thanks to the special surface of the inner fabric. Its double-layered, high quality, insulating material keeps you dry and your temperature under control, while the tight fit guarantees maximum body contact and freedom of movement, for all your koiski moves.
