During a 37 day tour of the Philippines, one of the things that i took note of is particular pieces of gear used during the trip (check out the first entry here https://pedalpowerphilippines.com/2017/04/05/biketouring-the-philippines-preliminaries-and-leg-1-manila-to-matnog-sorsogon/). One of which is the Ortlieb bikepacking framebag (you can check the specs here https://www.ortlieb.com/en/Frame-Pack/). Ortlieb is one of the premiere companies providing quality touring bags for decades and its 100% waterproof! Similar to their panniers, the framebag uses the same fabric -PU laminated ripstop nylon-light, strong and durable.

There are a couple of features that makes the framebag an excellent piece of equipment for tours:

adjustable straps to adapt to different frame designs and uses a combination of velcro and smooth cloth protecting your frame. The straps are robustly made-assuring you that you wont have problems making sure your framebag stays in place. The single compartment design with internal velcro strap prevents complicated use and even bulging when loaded. I particularly like this framebag as it fits the small Surly Troll perfectly and other similarly sloping downtube bikes in the market (i got the medium sized version) The heavy duty zipper is not only waterproof but can be locked when closed making sure that rain will not enter the bag. The medium size that i got can fit about 4 liters of gear. In the case of the tour, i placed all my personal stuff, gadgets, small items and even a small tab and fits perfectly. During the tour, we experienced light to heavy rain and several boat trips and my gear remained dry throughout the trip.

I got my framebag from Green Basikal in Singapore (https://www.facebook.com/theGreenBasikal/). You can check out other online shops for this item
