DrySpec D66 Modular Drybag System

The DSrySpec D66 includes one D28 and one D38 dry bag to create 66 liters of 100% waterproof storage. Modular packing has significant advantages over a single bag of the same volume. The two-bag D66 system makes packing and organizing your gear easier, allows for quicker access to your gear, and enables strategic separation of your gear; keeping your clean clothes separate from your wet tent. Each D-Series bag is also designed to mount directly to your bike, so you truly get three different bags in one. Use the D28 on local trails, strap on the D38 for around town, or connect to make the D66 for your longer adventures.


  • Includes a complete D28 and D38 dry bag
  • Modular packing (also mates with D20 saddlebags)
  • Universal slip-lock mounting straps included                        
  • Universal quick release mounting straps included
  • Mounts with or without toprack
  • Daisy chain mounting strip
  • Retro reflective logo
  • Strap keepers to secure excess webbing
  • 66 Liter capacity
  • 100% waterproof radio frequency welded seams
  • 22” L x 12” W x 18” H
  • 22oz vinyl and coated Cordura

DrySpec D66 Modular Drybag System 4.2 5 5 5
Great bag for a road trip Just for back from a motorcycle road trip i was able to pack all i needed for the week in the bags. It was easy to secure the bags to the bike and take them off at the end of the day. August 23, 2015
Great bags for the price I recently used the D66 along with the D20's on a 4000 miles trip. The bang for the buck is incredible! However, they were kind of a pain getting into and opening/ closing for 14 days straight. to get into the biggest bag you have to remove the duel end bag. For trips where you stay in one spot for a while they will work great, but if you move everyday for weeks at a time they become difficult (because they are all connected to each other and removing one affects the others). They did keep all of my gear dry and carry a ton of stuff. For less than $400 you get 106L of capacity, which is amazing for that price, so I cant really complain. July 10, 2015
Great bag, good price I recently used the Dry Spec on a 4 day tour of Colorado. There is a semi-rigid liner that ensures the D38 retains its shape, it was big enough so that i didn't need the D28 on this trip. The bag seems well made although the material is a bit thin. In pouring rain it remained 100% waterproof. The strap system is simple and intuitive. I managed to attach the bag (with 45 lbs of gear in it) securely with just 3 straps. Long term, i'm concerned that the material on the base of the bag is too thin and could be torn with use (the only reason it doesn't get 5 stars). However, it is a great bag for the price and I would recommend it. June 11, 2015
Sturdy, stable, versatile. If I had been able to give this product a 4 1/2 star rating I would have. First use of these bags was last summer on a 19 day road trip from CA to BC. Unlike the experience of a previous reviewer, securing the D38 bag to a 2013 Burgman 650 was straight forward. It rode on the passenger seat and up against the backrest with the four tie-down straps lashed to the passenger grab handles on either side. I suspect it would have worked just as well on my two previous bikes, a Suzuki Bandit 1200 and Suzuki GSX1100G (early 90s sport-tourer). Even though the ends of the bag overhung the Burgman's seat its internal rigid liner kept it from sagging or deforming. This liner also allows you to utilize almost all of the 38 liters of storage easily. Packing cubes seemed made for this bag, optimizing its capacity. This was not the case with the smaller 28 liter bag. While just as ruggedly constructed as its larger sibling it does not seem to easily hold as much as its specs would indicate. Rather than having two thirds or more of the usable capacity of the D38 it perhaps held half as much. If you plan on this going in you won't be disappointed. Packing cubes were less useful in what is essentially a somewhat narrow, thick-walled stuff sack. I ended up using it for things needed while traveling: extra layers, fresh tee shirt, gloves, hat, water, snacks, etc. For that it worked fine. The smaller bag connects securely on top of the larger one. At the end of the day only about a minute is needed to separate the bags from each other and the bike. In my case I tossed the four tie-down strap under the seat of the Burgman ready for use the next day. I plan on using them on my kayak for short touring/camping trips: they're that well made.

Great gear bags I bought these for a long road trip from Florida to Vermont and back. They performed perfectly and kept everything dry. With this setup and use of the many places on the bags to put straps, I was able to use an old saddle bag set in between the bags for some extra storage. These bags are very sturdy and keep everything dry and secure (not falling out of the bag or off the bike). My only issue is the straps and connectors that came with the bags with zero instruction were useless. I couldn't even find instructions online. I ended up using 4 pull tight/push button to loosen tie downs from harbor freight. The bag system is great just plan on picking up a strap system that will work best for you and your bike.

Aaron B asked: Does the D38 in the "DrySpec D66 Modular Drybag System" have a rigid core like the DrySpec D38 Rigid Drybag? It looks the same, I just want to confirm. Thx! May 20, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Casey B: Yes it's the same bag actually. The reason it's call the d66 is because the d38 combined with the d28 offers 66 liters total storage capacity. I just got the d66 last week and the bags are of awesome quality. Definately competitive with wolfman. May 20, 2015

brandon c asked: Would like to use this as a tail pack to have on the luggae rack of a Triumph Tiger 800 XC. Will be two up riding, will this be strong enough to have her lean against as a back rest? Jan 22, 2015

Michael S: This will definately be strong enough for her to use as a backrest. Extremely durable and heavy duty bag. Jan 22, 2015

Nowzar A: Even though I have not had a chance to use my Dry Spec bags yet (I ordered them at the end of my touring season), still as a long time motorcyclist and long mileage tourer I can offer my personal opinion on this question. I don't believe it is safe for a fully grown person to lean on these bags attached to the tail of your bike. The bags are of very high quality and the straps are strong, however, the straps are design for properly cinching down the bags and an adult leaning back on the bags would put undue stress on the straps and the attachment points. I would highly recommend an after market sissy bar or backrest to be installed behind the passenger seat. Jan 23, 2015
