Horween enumerates different kinds of Chromexcel hides.... -Aniline Chromexcel WP – the classic, hot stuffed pull-up leather -Beaufort Chromexcel – the same as the above, but with a different oil/wax blend. Designed to be cementable due to less oil. -Wooly Chromexcel – receives a different stuffing blend with a heavy addition of wool grease (lanolin) -Plainsman Chromexcel – A duller version with a more pronounced grain character -Kudu Chromexcel – Plainsman that has been hand-curried (oiled by hand) -Cavalier Chromexcel – Similar to Beaufort, with a lighter colored base tannage, allowing us to produce brighter colors. -Huntsman – a.k.a.
