Rav Moshe Shternbuch: Should We Wear Tzitzis To Bed?
We are not required to wear Tzitzis Min HaDin, unless we are wearing a four cornered garment.  The reason why we always wear tzitzis is because the gemara says that in times of Hashem's anger, Hashem will even punish us for foregoing an opportunity to be Mikayem a Mitzvas Aseh.  Therefore we make sure to wear a four cornered Beged in order to be able to be Mikayem the mitzva of tzitzis.

The Rosh holds that even at night you must wear tzitzis on a beged unless it is specifically a nighttime beged.  That means that our talis katan would be michuyav in tzitzis at night.  The Vilna Gaon paskens like the Rosh.  If so, why don't we wear a talis katan to bed at night just like by day?  In fact Rav Moshe Shternbuch (5:9) brings that Rebbi Akiva Eiger (Hagaos OC 21) says that according to the Rosh you should wear tzitzis to bed.

Rav Shternbuch says that neither the Brisker Rov nor the Chazon Ish slept with tzitzis.  He gives two reason why this is not common practice.  First because the mitzva of tzitzis is "U'Ri'esem Osam U'Zichartem", you should see them and remember the mitzvos.  This is not relevant in bed, and therefore Hashem does not punish for foregoing this opportunity. 

Another reason he says, is because our talis katan is not really a beged.  It only has the status of a beged because it has become standard for people to wear it.  Since at night it is far from customary among the masses, the talis katan would not be considered a beged and wearing tzitzis in it could possibly constitute Ba'al Tosif.  He says that because of the fear that our talis katan is not a beged, the Brisker Rov would not wear a talis katan on Shabbos in Reshus HaRabim.

He adds that although most Gedolei Yisroel are not noheg to wear tzitzis at night, if you are noheg like the Arizal, who said you should do so (although some say the Arizal only said it when there is no mezuza), Tavo Alecha Bracha.
