🚨🚨New product!
I've used the Blackburn Outpost Frame bag for 4 years now and its running strong.
Comes in 3 sizes and has an expandable bottom so can be used in conjunction with bottles or fuller frame if needs be.
Has a slim pocket on the side for phone / wallet etc and a removable divider in the main chamber.
Also has a sneaky hydration tube port so you can have a water bladder in it and a hose poking out, or a power bank with cables routed out to your bars etc etc!
Available online and in store.
