Good small bag

I wanted a smaller bag for day trips that wasn't too wide and this is perfect. Room for lunch / spares / coat etc and bonus of being waterproof. I don't intend to use the straps but have found the fixings perfect for attaching an external water bottle carrier on the rear facing the rider for easy access.


    Super waterproof bag

    Super bag, a good size, waterproof and perfectly matches Bertie.

    Fabulous service from Brilliant Bikes, I'm not sure that they could have shipped it any quicker!


      Does what it says on the tin, but...

      This was bought as a smaller addition to our Large Borough bag - wanting something smaller and totally waterproof, and it succeeds on both counts. However the plastic clip that turns the shoulder strap into shoulder straps clanks on the steering post, and has to be clipped onto the carry handle out of the way. The bag material is quite stiff, and totally different in feel to an Ortlieb bag.
