"Simplify, simplify," Henry David Thoreau advised us, in Walden. Here you can share this sentiment with the world! The adjustable ballcap says, "Simplify, HDT." One size fits most. The dark red short-sleeved t-shirt says, "Simplify, simplify," and carries The Thoreau Society logo at the back collar. Made of 100% rung spun cotton. Available in unisex sizes: Small, Medium, Large, Extra Large, and Extra Extra Large. The winning bidder will choose the size. How simple is that?
