The cavalry twill weave provides a texture unlike most other woolens. I have just reached into my wardrobe and simultaneously pinched a 16 oz serge twill and a cavalry twill - the former is softer the latter stiffer.I just received the loden PC Calvary twills and am underwhelmed in the fabric. Candidly I had to check to see if they were 100% wool. Contemplating returning them and eating the shipping charges. Was frankly surprised given how much love they receive on this forum.
