After a week of very light use the pull tab string began to frey, they were quick to send out a new tab and offer to replace the bag altogether. Certain areas of the bag worry me as I could see areas where chaffing from repeated use of the zippers could cause the material to become comprised. Perhaps some reinforcement on the corners. Can only speak on the commuter so far but very ergonomic. Can easily deploy under 2 seconds. Also would like to see more pockets for items, my personal opinion the velcro on the inside doesnt really do much for me. Tactigami pouches are pretty sweet and universal and provide perfect retention for my cz p10c mags.
