Muscle is a cut, not a size: a muscle tank is a sleeveless top and a muscle tee a short-sleeve one, and the size label on it (XL, 2XL, 3XL) is read like any other shirt label. Of the 7 muscle styles on SanMar spec sheets, only the District DT153 (women's) goes to 3XL, fitting a bust of 48-51 inches (122-130 cm). The unisex Bella+Canvas BC3483 and Next Level NL3633 stop at 2XL.
Method: compiled 2026-10-03 from SanMar spec sheets read 2026-10-01 (sanmar.com, style number checked on each sheet), with the source named beside every row. Where a sheet gives inches only, cm is converted at 2.54 cm per inch and rounded to the nearest cm.
Which Muscle Tank Comes in 3XL, and How Does It Compare to a Regular 3XL?
