I have long legs so it took a bit more looking to get chaps in "tall" size-- found some at loghomestore.com (professional type, as I prefer the wrap around the leg feature of those).
Most places sell "average" and Baileys also has "fat" size chaps, but at least from Baileys online store they don't explicitly show anything for "tall and skinny" (leg 40-42).
Finally, Baileys has the (more or less) non-toxic chain saw oil, which I prefer to the cheap toxic petroleum stuff way too many people use. This is the MotionLotion biodegradable product-- Baileys also sells the toxic stuff, just not marked as biodegradable. The biodegradable bar oil is made in Canada, one presumes the toxic stuff must be from China!
