I bought this second hand Eddie Bauer jacket at a Goodwill store for just $6.00 after my search for a new birding jacket at several local sporting goods stores came up short. It might not be the latest style but that shouldn't be an issue for someone whose wardrobe consists mainly of Dickee's work pants and Fruit of The loom T-shirts.
What I like about the jacket is the neutral color, it has 2 horizontal pockets deep enough to carry a field guide, it's light enough to use most of the year, and it has a zipper that doesn't get stuck (if you've ever had a coat with a zipper that constantly gets caught on the material then you know what I'm talking about). In addition, I paid someone a few dollars to add a pocket to the inside of the jacket which can hold the 5x7 Rite in the Rain notebook that I recently purchased.
Sometimes it pays to check the second hand stores. Not only did it save me money but I rack up a few points for "Going Green"!
