Medium weight. We typically run fits that are more boxy and relaxed. We tried to make this Tee a more "standard fit" but it ended up running on the small/slim fitting size. It is recommended to size up for this piece. The size small is perfect for "big kid sizes" and fits like a XL in youth - Lefty's 13 year old brother wears a size small. Lefty (typically a size M) wears a size Large in this piece.
