Four years and going strong!
I purchased my Hipster Bifold in December of 2013. I actually bought an extra figuring how long can it last as I was used to going through my leather wallets faster than I would like what with normal wear, over stuffing, cleaning out, stretching, etc. I just came across the untouched spare in a drawer and compared it to the one I have been using for four years... after brushing some lint away, no difference! Still looks good, works well, and as skinny as it can be even as I over fill it and empty if over the months.
ProsWears well, much thinner than any other wallet I have used
ConsCan't think of one
