Just finished 4 days of mtb bikepacking with restrap framebag. For a full suspension mtb, it is difficult to fill in the frame without interference from the suspension. This bag combined with toolbidon provided free good use of my frame
I bought this product for a bikepacking tour. I've covered a few thousand km since then. The frame bag is super handy for carrying a lot of heavy stuff. I put my Go Pro, chargers, camera batteries, leggings etc in it. In my opinion, the bag is very waterproof. I've caught some very heavy rain and apart from a slight dampness on the outside of the fabric, nothing else. I can only recommend it. The fixings are well designed and the pannier doesn't move a muscle. Fits perfectly in size M on my Megamo Jakar in size M too.
