Oooh, this is what I carry my EDC in instead of a purse! I have a small, leather crossbody bag that’s maybe 2″ x 5″ x 8″? One small pocket and two attachment points on the outside. It’s pretty small but holds a robust EDC, Leatherman, extra battery, and all. No links to a bag, sadly. It was a gift from my father who has “a leather guy,” so… no spec sheet. You might be comfortable with a heavier load, but if you’re trying not to stand out to others (and/or have structurally unstable collarbones), a smaller and less MOLLEd bag is nice. The crossbody stays out of the way when you’re walking or biking but allows easy hand access even while walking if you adjust it right. It lies pretty flat, so it doesn’t make maneuvering much harder. The leather is really durable, too. It’s been seven years of rough use and still going strong. You might need all the space those bags you linked will give you, but you can fit a solid EDC into much less if you want to. Heck, I’ve even seen decent ones in just pocket organizers.
