This is a knit from Tomorrowland's tricot line, made of 100% wool. It's thin and can be worn like a T-shirt, and is also recommended as an inner layer for a jacket. - Brand: TOMORROWLAND tricot - Color: Dark Green - Style: Long Sleeve - Material: 100% Wool - Size: Marked M, Length approx. 64cm, Width approx. 51cm, Shoulder width approx. 42cm, Sleeve length approx. 66cm The knit under the arms has hardened and felted due to friction. There is some slight pilling overall. I don't think it's particularly noticeable. Thank you for looking.
