I've got to the point I no longer trust anything claiming to be leather that doesn't look 100% hide and no tell-tale resin down the side to give away it's really 'split leather' and going to separate soon after. Have 2 real leather ones, one of which has been going well over 20 years now.
Not a lot of luck with canvas since early 90s. Latest one being polyester and slipping in the teeth after a few months.
My interest has perked in the LionVII canvas. But appears to be mixed reviews. Not terribly priced if the local experience has been little to no slip
