Ideally a garment should be checked if it contains wool, flax/linen, "Other Fibers" (O.F.) or "Mixed Fibers" (M.F.), or linen-look fabric. Textured garments with irregular, uneven fibers and white dots or streaks are also at risk.

All men's suits and jackets (even 100% synthetic) must be inspected because of the many internal components which could contain both wool and linen.

Consult a qualified shatnez expert whenever you have questions.
