Just in case you might be interested I have a pair of FXRG Harley pants, padded, etc that I bought when I got my bike, they have been taylored for my 30" inseam, still very much new as I have not worn them much. I paid over $500 when I got them, selling for $275 plus shipping, FYI. TTYS, Mark 98502
You can get decent chaps for under 100.00, but waist size and length are NOT used for sizing. You need to use the measurement around your thigh area. The waist is adjustable, and length can be cut down to fit. But if the thigh area is too large or small, you will have problems with them.
Look for a reputible independent shop in your area, many will have chaps in the 100.00 range.
Also if you have a Farm & Fleet or Fleet Farm in your area they have reasonably priced good quality chaps for under $100 and have many different choices and styles
