An authentic motorcycle jacket in Sylkoil.
Sylkoil is Barbour's oldest (and most traditional) wax cotton. It's an unshorn, woven cotton with a rich color and finish. The fabric is matte in appearance, and has a drier handle than the Thornproof wax cotton. Sylkoil is made in three weights: 4 oz., 6 oz., and 8 oz.; this jacket uses the heaviest version.
