L.L.Bean offers its L.L.Bean Men's Lakewashed Cotton Chinos in Burnt Sienna for $29.99 with free shipping. That's $20 off list and the lowest total price we could find, although we saw them in different colors for $3 less three weeks ago. They're available in waist sizes 30x29 to 36x34, although not in all size/length combinations.
