Hi gents, Any experience with replacement waistband knits from Larry over at Flightjacketknits? Particularly the single ply M422a type. Mr Steve Sellers from Headwindmfg is making me an M422a and I am vacillating between ‘authenticity’ and ‘longevity’. ‘Authenticity’, being the std single ply M422a waist knit and the ‘longevity’ being the A-2/ later G-1 double layer waistband. I have a set of the A-2 replacement knit, and its very good, but do I want this on my M422a? Then again, would the single ply stretch out and loose shape? Thoughts?
