Blackburn's Outpost Frame Bag makes use of the empty space in touring or bike-packing frames and keeps cargo weight centralized for predictable handling. External mesh and slip pockets put essentials close at hand, and the zippered main compartment includes a baffle to help keep things organized. For picking up extra items along the way or for when repacking gets a little untidy near the end of a trip, the bottom is expandable to create some extra room, which is always welcome.

A perfect bag for a week long adventure or an all day pleasure ride. An expandable bottom compartment accommodates more mission critical gear.

Features a hydration hose port for use with water reservoirs. Water-resistant. Available in two sizes.


  • Medium (4.2 L - 5.8 L): 18" Length x 2.5" Width x 7" - 11" Height (Expandable)
  • Large (5.25 L - 6.95 L): 20" Length x 2.5" Width x 7" - 11" Height (Expandable)

The frame bag fits my bike and my needs.

I put this frame bag on a Trek Stache 9.7 size small. I got the small bag and it fits snugly. The exandable nature of the bag is good, and when expanded, it fills the main triangle completely. I can put in my frame pump, a thick pair of winter gloves, tire levers, multitool and a tube. That pretty much fills all the space. Attacment is easy, although the front and rear belts have a long floppy end that needs to be tucked in somewhere when the are tighthened up. I just wrap the loose end around the frame and tuck in the strap. The bag has performed well in 0 degree winter weather and so far the zippers have worked fine. It does not get in the way of peddling either. S

Nice bag with plenty of storage. Haven't used it much as i have another bag and this bag is too big to get my water bottles out. I have the medium size.

This is a really nice bag, but even the Medium-sized version was too big to fit my Rockhopper 29er. The price was very good - I saw the same bag in a retail store for 50% more.
