I'm really liking my redington sonic pros....though I'm only wearing a large. They do make large longs. I'm 6' 215lb with a broad chest and a large fits perfect. They are about the nicest fitting waders I've even put on. And I bought a pair of Simms 3 days before trying on redington sonic pros....guess which waders got taken back that very day.

Looking at the redington size chart they don't list a longer inseam length between the large and large longs. But I can tell you from trying them on that they are longer by about 1 1/2" and the foot was bigger by a size or 2.
