New to going /out/. Wondering about personal hygiene when hiking places.

My main question is: should my technical fabric t-shirts smell so bad?

I can sweat in cotton t-shirts all day and the next morning they don't even smell bad. I bought some of these moisture wicking t-shirts, go for a 1 hour walk in one, leave it to air and then it smells like classic B.O., like 'that one kid in school' smell. I shower and use deodorant etc, never had this problem with other clothes.
