Fly national pride and state spirit together with this Made-in-USA polyester flag bundle. The set pairs a U.S. Polyester American Flag with a South Dakota Polyester State Flag — both woven from rugged 2-ply spun polyester built for high wind, coastal conditions, and year-round outdoor exposure. Both flags are sized for correct side-by-side display per U.S. flag code, with the American flag always at the position of honor. The South Dakota state flag features the state seal on a sky blue field surrounded by a serrated gold sun — with 'South Dakota' above and 'The Mount Rushmore State' below — representing the state's Great Plains identity and western heritage. South Dakota's open plains and exposed Black Hills locations see significant sustained wind across most of the state. Polyester is recommended for most South Dakota properties; nylon may be suitable for sheltered residential locations in Rapid City and Sioux Falls but polyester offers better long-term value for the state's typical wind conditions. Available in multiple size combinations to fit residential poles, schools, businesses, and government buildings. All flags are FMAA Certified and proudly made in the USA. For a standard 20' residential pole, the 3'×5' American flag paired with a 3'×5' South Dakota state flag is the most popular choice. Step up to the 4'×6' pair for 25' poles, or the 5'×8' combination for 30'–35' commercial poles and larger residential installations. Ships in 1–2 Business Days · Free Tracking · 30-Day Returns
