I purchased this bifold wallet approximately about a month ago for my husband. It seems to have the trusted durable Carharrt quality, but it hasn’t been long enough to review its durability. It’s very nice looking. I gave it a four star due to he did find it stiff & tight fitting at first, it didn’t fit all that he had in his old wallet. I’m sure with time as with any leather it will soften.
