Our new Denison smocks feature improved colors and sizing, original WWII knit cuffs, a khaki wool collar lining, reproduction Newey snaps and Lightning zip. These are the best we have ever done. The full zip model is a modified first pattern smock with knit cuffs and no snaps in back to hold up the tail. The tail was frequently eliminated as part of the modification, but we leave this up to the customer to do this if desired.
