You can buy all the crap (travelpro, tumi, etc), but the best that I own is made by Glaser Designs. I own 3 pieces from Glaser Designs...the two pieces of luggage are the: Short Hop Garment Bag (perfect for 1 week trips) and the Three Suitor Garment Bag (perfect 2 week or longer trips).

Both pieces are made of excellent materials and craftsmanship. If you are ever in SFO go visit their shop/store its incredible.

The other piece I own is the All Leather Deal Bag which I can easily carry my laptop and other work papers. I have owned this bag for over 10 years and its in great condition.
