ILM mens Bjn01 Sport-motorcycles

My waist diameter is 31" i normaly use 32", and it´s ok, but in the web it's written (waist32''-34'') so i´m not exactly sure about the correct size?

I used the washing machine and dryer on these jeans. Have l ruined their protective qualities?

What is 32L in the length

What is the fit of this jeans , is it a straight , relaxed or skinny and how is the waist line on the waist or below the waist
