The luggage is all Happy Trails. 9" Teton Pannier and their big flat top box. The panniers come in different widths and sizes.
I will say one thing. The top box I chose for the DR is BIG. It remains to be seen if Kim will ride with it or we use something smaller.
Anyway, you can check out the DR specific Happy Trail Panniers here:
Tim Bernard is the owner and a super guy. I can't say enough about the luggage. When we went on the Atlantic Canada loop last year, Kim had Jesse panniers and I had the Happy Trails. Lots of rain and mud etc. Guess whose panniers leaked like crazy? Also, the Happy Trails are lighter than the Jesses. That's why Kim now has Happy Trails.
