Q. Can someone carry in his pocket pages of Divrei Torah or a Siddur when he enters a bathroom?
A. Horav Shlomo Miller Shlit'a permits in principle since the pockets of jackets are made of double material.
However, as Horav Aharon Miller Shlit'a told me, the Rosh Hakolel is stringent himself.
Rabbi A. Bartfeld as advised by Horav Dovid Pam and Horav Akiva Steinmetz Shlit'a
