The Lead Off T-shirt from Jackman is a modern staple rooted in old-school athleticwear. It’s made from a dense, dry-touch cotton jersey that’s knit in Japan for durability and long-term comfort. The fit is slightly boxy with dropped shoulders for a relaxed silhouette that sits just right without feeling oversized. The standout feature is the wide ribbed collar - reminiscent of vintage baseball uniforms - which gives the tee its signature identity. With careful attention to sewing and structure, this shirt feels substantial without being heavy. Built at Jackman’s factory in Fukui, Japan, this is a quiet essential done to perfection. 100% cotton Dense, dry-touch jersey fabric Wide ribbed collar inspired by vintage athleticwear Dropped shoulders and boxy silhouette Straight hem with a relaxed body Garment-washed for softness and stability Made in Fukui, Japan Size Body Length Chest Width Shoulder Width Sleeve Length S 26.77" 20.87 17.32 10.63 M 27.56 21.65 18.11 11.02 L 28.35 22.44 18.90 11.42 XL 29.13 23.23 19.69 11.81 XXL 29.92 24.02 20.47 12.20 A variance of .5" is within tolerance.  Fit Notes: Shop owner Tommy is wearing a size large in the pictures. He tends to like the fit both pre and post-shrinkage in the size large almost across the board. The lead-off tee is a really killer modern cut with a bit of a boxier body and longer sleeves. We recommend buying either your true Jackman size or one size up from your normal size. Tommy is 5'10," 165lbs with a 40" chest.  table { width: 100%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: center; } th { background-color: #f2f2f2; }
