It is good and correct that a person should be cautious to wear a small tallis every day, in order that he should remember the mitzvos at every moment.

Indeed the Gemara in Menachos 41a relates a fascinating story about a dialogue between Rav Ketina and a malach who tells him off for not wearing tzitzis. Although it wasn't regarded an aveira, Rav Ketina's inability to perform a positive mitzvah gave rise to a punishment during a period of Divine anger.

With this in mind - are there any poskim that talk about wearing Tzitzis whilst doing sport. Surely the resultant sweat and grime that builds up is a g'nai (disgrace) for the mitzvah and thus would it be better to not wear them whilst doing sport? Or, even if the beged gets soaked with sweat, that is still preferable as you are continuing to wear your tzitzis?

    The angel tells off R' Katina for rounding off the corner of his garment to avoid needing to attach tzitzit, not for not wearing tzitzit.

  • @DoubleAA my point was more that the result of not wearing tzitzis elicited a negative result

  • That's a point unsupported by your source. The act of purposefully altering the clothing you were going to wear anyway to remove it from the obligation of tzitzit elicited a bad result. No angel will smite you for having a different fashion sense and preferring round clothing.
