It is at 40 degrees washable (hand wash) and you can iron on level 1 if you do not like the Knitterlock. If you want to get the Knitterlock, you have it in the wet state after washing rotate in the opposite direction until it devours itself, then secure it with a rubber band and let it dry so. With strong crease is narrower. Should it be too tight, it can be just a little stretch and then it will continue.
At the waist, a rubber band is incorporated, and the sleeves are slightly narrower overall and not too loose. Apart from the somewhat narrow bust I like this shirt very good and 4 star has earned it.
