    Bags work with Moto Guzzi V 85 tt panniers


    Spoke with TT and they confirmed the Dry Bags are only 45 L now, 37 L no longer available. The side panniers on the MG V 85 tt are 33 L and 38 L. These bags work well . Two folds to close and they are the proper height. The top box on the Guzzi is 48 L (some sites state 42 L, but I think it is 48 L). Anyway, the top box dry bag is a little short front to back, less side to side, height is fine. The left over space is fine to pack other items that you may want access to without opening the bag, so no downside IMO. The bags are fairly thin but well built, so not bulky and fit the spaces nicely. There is velcro across the entire opening which ensures the bags close securely. Obviously these are new so no feedback on durability, but evaluating a new product I am pleased with this purchase. Quick shipping. FYI for other MG V 85 tt owners.

    Quality product but too small for 45l boxes


    Been using this in my 45l TraX boxes and while the quality, material and the whole idea is great, it’s just too small.

    As it is right now, once I fill the bag up and put it in the box, I still have room for 2 sets of shoes and 2 sets of rain gear. So I just compliment it with a couple of extra smaller generic dry bags. Not ideal, but not the end of the world either. As soon as I find something that fits the boxes better, I’ll replace them. I imagine it would fit way better in the 37l cases.

    Perfect liners for my need!

    I’ve been using these bags for a while now (2+ years as I won’t review a product until I’ve thoroughly tested it) and they are holding up very well.
    I have some home made panniers on my KLR which are exposed to the elements (but very lightweight!) and searched around for some time to find the perfect fit dry bags for them. They are typical dry bag roll top/buckle secure design but pannier shaped (obviously!) instead of cylindrical. I also appreciate the continuous strip of velcro at the top for an even better, more secure closure.
    Would highly recommend these if you’re needing waterproof pannier liners!
    Sorry….I tried to add pics but said file to large. 🙁
