I've carried this bag on every trip on two bikes (T7 and 1250 GSA) over the last 45,000 miles. Several BDRs, the Trans America Trail, the Continental Divide, and 4 times across the US. Its the 44 liter version and it carries a bunch of gear without being too big. It always stays waterproof, and there are zero holes wore in it. A wash and a wipe and it looks new again. The fact that it has a burp vent is vital to rolling it up tight. If this ever wears out I will buy another one. Matter of fact, I'm getting one now just in case.

I bought the large Tusk duffle to use with my Highland saddle bags for a long trip. The additional size helped with the additional items I wanted to take.

I was able to hold all my camp and personal gear in this bag - hammock, quilts, tarp, clothes, personal items, etc. This allowed me to take the bag to my camp spot and leave the rest of the gear next to the motorcycle and cooking area. Many days and nights of rain - a few torrential - and never had to worry about any gear getting wet.

The air release is a small but very beneficial feature.

One item to note, this large bag is enough wider than the medium that you pretty much need to remove it in order to get into the side panniers. It took a little bit of trial and error to get everything packed in the proper location, so I did not need to access the side panniers on a normal day. Most accessed items where in the attached pockets, less likely in the top bag, emergency/nightly/cooking/food in the side panniers.

Not only do I use this on my KLR, but I use it on my sxs as well! We take some pretty remote trips on 2 and 4 wheels and this bag has been perfect! I bought the 40L and it is small enough to bundle down tight and big enough to hold whatever I need! Very versatile and has held us great! Love Tusk products!

Received with in 2 days. Good Quality, like the air bleeder, when put on my KLR 650 length ways makes a good back rest. Takes a while to thread straps through the buckles and frame. but this would be the same with all dry bags.
Cannot really rate durability as only used it once so far but it looks good

Very happy with this bag. Great build quality, thick, durable, and completely waterproof.
Plenty of external D-rings and straps. You can pay a lot more for a similar bag, but I doubt
it would be any better. Unless you just enjoy paying for a name...
