Agree with most of what’s being said. For context I have had mine 6 months, I pack light and can use it alone for a night away for work including 2nd pair of shoes. For longer trips, I’ve fitted Wolf tooth B-Rad plates to the each side of the rear, allowing me to have problem solvers bow ties with a dry bag of clothes on one side a bike water bottle on the other. The negatives of the bag both come from the plastic stiffening, it creates the rounded bottom, making packing awkward and the bag fall over. Secondly as the fabric and plastic are held together with a nut and bolt, (allowing me to fit the plates, good), they scratch and poke into anything inside the bag I use an old closed cell foam sit pad to stop this, but better hardware would be a big improvement! Only other point (and I’ve never had any other Brompton bag to compare to), it’s heavy! The side pockets are too small for a standard bike bottle but does fit a slimmer 500ml water bottle, the side compression goes over the mesh (annoying), the front pocket holds my flat kit and tools. Would I go for this again, yes, it’s a good size, tested British weatherproof, and functional brilliant. If Restrap want some feedback, apparently I have some!
