Designed for outdoor use, these beautiful long-wearing 3' x 5' Colorado flags are crafted from the highest quality 200-denier nylon. The colors are dyed into the fabric for superior penetration and color-fastness. Attaching to a pole is easy with a pole hem on the 3 foot side to slide onto a pole.  A tap at the top will hold the flag in place. The hem on the fly end of the flag features 4 lock stitched rows to help prevent premature fraying. The authentic designs are based on information from official sources.
