I excise dedicated compartments from my purses and luggage. Individual special-purpose kits in zippered packing cubes or high-tech zip-close plastic bags corral inventory and are easy to shift from tote to tote.
Such is the nature of my daily life that I use a rolling under-seat airline tote in lieu of a purse. Chopping my share of packs and side bags led me to zip open the lining of the tote. A good eighth of the interior space lay between and alongside the telescoping handle of the piece. I stuck lengths of male hook and loop tape onto the rigid plastic back of the tote and short lengths of female tape onto each kit. I can now carry field essentials with no waste of the space that holds the daily payload of shopping, study gear, and gym amenities.
