This is an OAMC sweatshirt. The fabric is 100% cotton, thick, and has a brushed back, so it's warm. The size is M, with a shoulder width of 53cm, a body width of 60cm, and a length of 64cm. Unlike the current OAMC, this item is from when Luke Meier was still involved, so it's sturdy and the quality is quite reliable. It has been worn a few times and is in good condition. Thank you.
