If you're sweaty enough to want to change your talit katan, I would expect you to want to change other clothes too. The only thing that makes this plausibly on-topic here is the talit katan, but I don't see why the talit katan is central to this question. Absent further explanation of the
Jewish context for the question, I would nominate for closure (or migration, if Bicycles or Freelancing would fit). —
