Overnight weekender bag suggestions, help!

I have a Maxx NY overnight bag i like a lot. It holds a ton and does not get all that heavy. Handles and shoulder strap. I am usually going by car so never needed the strap.
I don;t even own a Dooney & Burke but i've seen their all weather material..i can't think iof what you call it but it is the same material used on convertible car tops...someone help here lol...and they seem very sturdy and roomy.
Darn i saw one the other day but i forget where or what it was called...i just know i thought if i went places more and did not already have a nice weekender i'd have grabbed it. If i recall the name i'll be sure to post it. Oh and i recall the name odf the D7B material now...Cabriolet i believe it is!!
