Women's Fit 509 Logo Long Sleeve ShirtA great fitting, thin and soft material you will love. Show some pride for the dry side. These make great gifts. What the heck is this "509" stuff?If you know the geography of the Pacific Northwest, you probably know that the Eastern Washington is very different than Western Washington. The east side of the Cascade Mountains is high desert and rolling plains. Its also very rural. Its also very trouty! This is where Red's is at. The "509" represents our area code, which is different than that of the concrete jungle around Seattle. Since many of our customers work in Seattle, but play in the "509" this logo just makes sense. Its lets folks know, "hey, I love eastern Washington".
