Review by Woodster
I do some camping and put on about 15,000 miles a year on two wheels and was tired of my stuff being wet. No more. It's a little hard loading it at times but I love it. (Posted on 5/30/2016)

I submerged this bag in several rivers in Alaska and otherwise abused it horribly. It took it all and never failed me. (Posted on 2/13/2016)
Review by Bill Rides
Recent purchase - only used 2X so far on dry rides. Seems overpriced for thickness of materials. Not completely rigid - plastic liner will flex under load, so check clearance on fenders and saddlebags to avoid paint damage if bag is not fully supported by a rack or seat.
Holds a week's worth of big and tall man clothes - pack corners first due to narrow opening. Loop straps work well on a FLHP rack for long rides, but bungees are more convenient if you need to remove quickly and/or frequently.
Only gave (3) stars due to price, flex under load, and yet TBD durability. (Posted on 11/19/2015)

I bought this as a tail bag so I can remove my side cases around town and for touring. Compares very well to the competition and is large enough to stash all of my riding gear. It is well made and appears very durable. Fitting it to the bike takes a little trial and error but it is a simple process. My only complaint is the same as other reviewers, the opening is way too small. Yes I can fit my full face helmet inside but the opening makes it a bit of a struggle, especially if the bag is already partially full. Twisted Throttle, you have a great product here, but you lose a star due to the small opening. That said, would I buy it again? Yes. I may even add the side bags as an alternative to my hard cases.

I've tried a lot of different bags like this one and the D-38 beats them all. Good looks and performance makes it the best in class. (Posted on 3/24/2015)
Review by Bigboy61
I bought the orange colored dry bag and I took it with me on my fall trip to Deals Gap this year. Very easy to attach to the rear of my FJR1300. It holds a lot of clothes and other equipment. I am very satisfied with this purchased. I may get one of the medium sized dry bags to attach to the top of this large bag.
The bag is waterproof and will keep your items dry. Highly recommend this item for anyone traveling. (Posted on 1/6/2015)
Review by Kohburn
Sold my Givi hard bags and bought this as part of the D78 set. I love this bag, the size is perfect for most things. Yes the opening is a little tight due to the nature of the bag and the limitations that the bag stiffening insert create, but it is very manageable if you load the ends first with smaller items. It is stiff enough that it can be strapped to the rear pillion seat without the need for a rear rack. I leave this one attached most of the time as I commute to work 5 days a week rain or shine and it makes the perfect trunk, if I happen to stop in a place that i don't want to leave it behind then it is much nicer to carry around as a duffel than a hard case would be. The majority of my use is daily commute including 50 miles and a ferry ride salt spray and all, but it also gets some sport touring and adventure rides. (Posted on 11/12/2014)

Review by PJTX
I rode the Colorado back country discovery route late july. This bag sustained some punishment. We got stuck in nearly 18 hours of torrential down pour and not one leak into the bag. I held a tent, sleeping bag, my cozy liner, little pillow, sleeping pad, little chair, camp towel and toiletries for 8 days in this sucker and nothing got wet! The only issue I had the bag was that one of the pockets came off and the other is starting too peel off as well. The guys at twisted offered to replace the bag at no charge, i declined due to the inability to use said pocket when the bag is stuffed to the gills. I also enjoyed the mounting system that came with the bag simple easy it was nice to free up my other straps for hauling wood and beverages during the trip. I highly recommend this to anyone looking for a streamline waterproof bag. (Posted on 8/14/2014)
Review by WvJohn
Purchased specifically for 6k trip to South Dakota and the midwest. Though not a tremendous amount of rain, it keeps all dry when it does pour. As mentioned before, really is a puzzle at times to pack this bag. The opening is narrower and shorter than the bag so hard to get items in the corners.
Would be an easy 5 star rating except no directions with the straps. We never did figure out their loop system and used Kreiga straps and rope to secure it. Even googled the issue but did not come across the strap system. (Posted on 8/13/2014)

I bought this bag before my trip and it really worked well. There were times I thought it too big but it fit really well on the back of my 2014 Yamaha Super Tenere ES. The side pockets are to small for anything other than a card. I was very concerned about the mounting strap system but it worked very well I think that one of these mounting straps will be the first thing to break. Can replacement straps be purchased?
I never worried in the rain I knew it was water proof. I really like the side stiffener it worked very well.
The opening is a bit small causing a bit of "work" putting things in or getting them out. However I believe this helped to insure how water tight the bag is.
I purchased the Orange bag so it could be seen.
It could benefit from some reflective material/panels particularly on the ends.
It was an expensive bag but I am pleased with it. (Posted on 7/7/2014)
