I do not feel comfortable wearing pants, but I usually do wear them outside.
Can I take them off every 15 minutes if I am overheating?
In fact, we had one guy at YK services who felt it necessary to wear mask on a beard davka to talk to hid neighbor. I made a quick sign with my hand as if to show him that his zipper is open. He quickly looked at his kittel and then back at me with a question in his eyes. Then, I made same zipping sign near the mouth. I was not sure how it will be accepted, but it was.
