Tallit are the traditional shawl worn by Jewish men during prayer.  In many progressive congregations both men and women may wear a tallis during a service.  

The Custom at Temple Beth Israel is to reserve the choice to the individual participant. Since the Temple does not provide tallit, those who wish to use one must bring their own.

Tallit (TAH-lit; TAH-lis)

A shawl-like garment worn during morning services, with tzitzit (long fringes) attached to the corners as a reminder of the commandments. Sometimes called a prayer shawl.
