|TR's leather coat. It says so at the website.|
When I looked at the items on sale, I realized that except for the leather vest and the national parks atlas, I already have everything on the page or an equivalent garment. Right down to the pocket watch and the biography.
Maybe I could substitute my leather-covered copy of David Sibley's bird book for the atlas.
A woman in a coffee shop once told me that I looked like Teddy Roosevelt (really, I don't) when wearing an old four-pocket twill jacket that was made by, guess who, Orvis, but purchased on eBay.
There is also a "trout bum" collection, but I somehow doubt if John Gierach gets a cut on sales. He did not invent the phrase, but he sure did popularize it.
