p. 31 Chapter Ten Al HaShulchan
4. Clothes which are open at the sides and have four corners at their hems but are closed at the top if most of the side is closed then they are exempt from zizit, but if most of the side is open they are obliged to have zizit affixed. If half is closed and half open the rule is to be stringent to oblige zizit, however it is forbidden to go out of one's private domain on Shabbat when wearing it in a place where there is no suitable Eruv (boundary approved and supervised by an Orthodox Rabbinical Authority) (Shulchan Aruch 10:7,8)

Shulchan HaMelech, a Kitzur Shulchan Aruch in 3 volumes as compiled by Maharan HaRav Shmuel Laniado z'al, 1923 with the supplement "Al HaShulchan" containing various opinions compiled by Ezra Basri, Chief Justice of the District Court, Jerusalem in 1992.
We would like to dedicate this learning for the speedy and complete recovery of two people: our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia, and a longtime friend of the family, Frank, son of Joseph, having thyroid surgery soon. Please have them in mind when studying. If you would like updates on their progress, please let me know so I can tell you when I find out from either or both.
