I got these
Tactical Molle Pouches for five bucks with a coupon from aliexpres to get a bit more storage space before I get a Brain Box. Enough space for my rain-gear, arm/leg warmers and a wind vest, so not too bad.
We'll see about how durable they are, but they seem to attach very securely to the straps on the side of the OFA bag.
Usually it takes a month for stuff to get here from China. Got these in a week so don't know what's up with that.
