Menards sells Masterforce brand pouches that are well-constructed, durable, and CHEAP. They even have
an ear on the outside to attach to. They don't have any attachment point inside the pouch though so I modify
them for that.
I turn the bag in-side-out, cut out the divider except for one corner, cut a hole, install a grommet in the
hole, turn it back right-side-in, and attach a small s-biner as an attachment point.
