Blackburn Outpost expandable frame bag

Ive used the Blackburn Outpost frame bag for 4 years now and its still 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!

If you are between sizes I would suggest sizing DOWN - this allows for zips to be pulled taught and easier to use whilst riding.

Comes with velcro straps, and has webbing all around if you wanted to use different straps or weave it on with cord.
