Annin flags. Believe it or not Walmart sells them for under $30. I buy the 3X5 nylon. we fly it 24/7 in NE Florida and barely fades or frays over the course of a year. Outstanding flags. Made in USA (Alabama, i think)
Used to buy Valley Forge brand but Annin are superior in just about every way. Valley Forge is also made in USA.
Sorry, forgot that you also asked about poles. I use a wall mounted flag pole mount anchored to our brick walls. I use a 7ft x 1in (OD) aluminum piece of pipe for the pole. Aluminum is light and more flexible than wood or the mass produced poles sold in bigbox stores. My aluminum pole has been up for close to 10 years now.
