I have been wearing Levi's 501's for most of my life.  I have always purchased them at JCPenney and they have lasted many years without issue.  I purchased these 2 pair on Amazon and was disappointed to have them both slowly wear and rip out at the crotch along the seam in just 5 months.  The pair I purchased with Amazon I noticed were manufactured in Mexico and had a different tag than my normal jeans.  I noticed my old jeans are all made in the USA, and JCPenney states their Levi's are made in the USA.  I will only buy Levi's that are made in the USA in the future.
