From the brand: The Lead Off Long Sleeve from Jackman builds on the same vintage athleticwear roots as the short sleeve version, with added coverage for cooler conditions. It’s made from a dense, dry-hand cotton jersey that’s knit in Japan for structure and long-term wear. The fit stays relaxed with a slightly boxy shape and dropped shoulders, designed to feel easy without leaning oversized. A wide ribbed collar nods to classic baseball uniforms and sets the tone for the whole piece. With flat seams, ribbed cuffs, and Jackman’s signature attention to balance and proportion, this long sleeve delivers a timeless silhouette with a clean finish and substantial feel.

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. 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.
