Lots of brands and models so take your time in checking them out.
I've have 1/2 doz. different T-Bag styles for my different bikes. They have a life-time warranty. I had a zipper opening at the wrong time on my "Baja" bag for the Sportster and they replaced it with a completly new bag. This was after using it for years. No questions asked.
Great service.
I have an "Iron Rider" Main Bag for short trips. Holds enough to get me around.
I used my T-Bag "Dakota" for the 2,000 mile ride to the coast with the Ultra. Held plenty and has two handy places (one on each side) that can hold the passengers drink. She just reaches over her shoulder and there it is.
Have fun looking.... all part of the purchase.
