DeadCreek is thick with a inner removable lining with a pocket. They also sell mounting plates

 

I also have used the 5 inch leatherworks bag for years and it is awesome! Its my main travel bag for trips also. You can really load it up. When you open the top, they have some folded in side flaps that move up so you can load more and the straps have a lot of length and holes so you can still latch them properly.
This bag is top quality, strong heavy leather and holds up well...4 years and counting on mine.

 

I bought a like new used HD bag on eBay last year for $55. So far so good.

 

I agonized over which bag to buy and looked at all of them several times.

The Viking Bag is probably considered the bottom of the barrel. I mean, what do you expect for $89. It's synthetic leather and isn't all that big. I decided to give it a try since it was so cheap.

The back of the bag is plastic covered in "Viking Leather" (vinyl / syn leather). This is actually a good thing since I was going to hard mount it to the bike. I traced the bag on a piece of cardboard for a template and was able to position it on the bike so that I could use the 3 bolts from the belt guard to mount it. I then used the template and marked the holes on the bag and just drilled the back of the bag. I used different length 5/16" bolts and 3 plastic spacers to mount the bag to the bike.

Honestly, once the bag is on the bike it looks like all of the others. I'll use it until it no longer fits my needs and replace it with something better and US made. For now, it works.

 

I have a viking bag on my Fat Boy. I like it and it looks good. Holds enough for a long days ride and is sturdy. I think it's a quality made bag. It's just not real leather which doesn't bother me.
