The Seamless Flex Long Sleeve from Rönnisch is a long-sleeved training top designed to be a base layer when the temperature drops. Its soft, seamless fabric moves with you, while ventilation zones at the front, sides, and back allow airflow where it’s needed most. The material is breathable and moisture-wicking. The fit is tight, with a slightly cropped length, featuring a logo print at the front and a jacquard logo at the back.
