Levi Strauss Signature GoldMen's Regular Fit Flex Jeans, Westwood, 34W x 32L

Is the patch made of leather or vegan-friendly material?

Are there differences of size and cut between levis jeans and signature jeans? that's my doubt, thanks

Can you dry it?

I’ve worn American eagle jeans for years but they have switched to all “flex” styles. Not my thing. Can anyone tell me if these have a similar fit?
