Ah interesting. Looks like a good solution. Might be a bit of a problem if it’s my only bag on the bike though.
Half tempted to try and make something in the meantime tho.
Rather annoyingly I’ve just given two old waterproofs to charity that would have been ideal to butcher haha.
Harnesses and dry bags. Outershell Handlebar Harness or Straight Cut handlebar harness. I have an unused straight cut that I’m looking to sell.
