The DRB Edition Old School Field Blanket (O.S.F.B.) is a locally handmade, heritage styled merino wool lined ground cover, backed with a weather resistant 6.5oz waxed cotton canvas, and rolls up neatly for storage and transport in a hand crafted rugged full grain belt leather and brass hardware carrier. Vintage field blankets like these were typically kept handy in the cab of a pickup, car trunk or cargo area of the family station wagon; to be used for camping, picnics, outdoor concerts and more. Our DRB Edition O.S.F.B. is an American outdoor classic made right here in San Francisco, with the best in materials and hand craftsmanship.
