Black chrome echo bravo backpack. Only used for two weeks then sat in the cupboard, so it's close enough to brand new condition.
Fully waterproof. Found the compression straps super useful on this one and can include a jumbo waterproof sack (imagine a massive super tough ASOS delivery bag) to be used with the straps.
Can meet in Shoreditch in the week or Finsbury park evenings and weekends, but also happy to ride most places so let me know where you're at.
