I purchased my Aqua Quest White Water Duffel in November 2015 and have been very pleased with it. Aside from the bag being quite large (75L – they do have smaller sizes), it is well constructed, with heavy metal “D” rings in just the right locations for running tie-down straps through to securely attach it to the rear fender of my motorcycle.
The bag features a roll top, with interior velcro bands near the opening to keep the top from opening. Once packed, you roll the mouth of the bag down to the desired size and secure it with four external m/f clips (two across the top opening, and one at each end of the top opening), to keep it secure and your contents safe from the elements.
An attached velcro sleeve on one of the hand straps allows both straps to be kept together when transporting the bag, and a very comfortable, adjustable shoulder strap can be removed or added as needed; given the fact a 75 liter bag can contain a lot and get rather heavy, a comfortable shoulder strap is a must! I can easily carry my CPAP machine, toiletries, and several changes of clothes in this bag and still have room for a few souvenirs I may purchase while I’m traveling.
The bag is heavy nylon, waterproof lined, reinforced seam construction. It feels like it will hold up to a lot of use and beating. As I previously mentioned, I throw my bag over my rear fender and across my saddlebags; this also allows it so serve as a nice backrest. I then secure my bag with two Rok-straps (another great accessory for road travel).
