Spacious bag

This is the largest official Brompton bag. It can hold a lot, but ultimately is still compact and well thought out like most things Brompton. The rolltop gives you some flexibility. The back pockets are nice too. Do note that the rain cover tucks away in a semi-hidden pocket behind the right rear pocket. I wasn’t able to find it at first but the great folks in the REI bike shop were able to figure it out and explain it over the phone.

Nice BUT NOT WATERPROOF

I bought this bag for a bike tour. The description says “waterproof” and “comes with a Hi Vis cover”. Well I can definitely say that it is not waterproof as described by REI. It also did not come with a HiVis cover again as mentioned by REI. So REI, if you are reading this, please amend your description and buyers be aware. I’m glad I wrapped my electronics,valuables and passport in a garbage bag but my clothes got soaked inside.
