Shaatnez Laboratory

Shaatnez (wool and linen) is often found in garments bought even from a reliable Jewish clothing store. Therefore, it is forbidden to wear any man’s, woman’s or child’s garment that contains wool or linen until it has been determined not to contain shaatnez. To determine whether your garment is shaatnez-free, garments may be dropped off at the Kehilla office during regular business hours (Mon-Thu 9:30-4:30; Fri 9:30-12:00).

If you are not available at those times, please make an appointment by emailing If you do not have email, call (917) 359-2873 and leave a message.

Rabbi Kalman Strauss will test the garments on our premises.

Please note that it is important to leave on tags with information where garment is manufactured and list of materials contained in it.
