Hi everyone, for an upcoming project of mine (new EDC backpack) I've been putting a lot of thought into making a concealed quick access method for pepper spray and a 18650 flashlight. So far I've come up with a few ideas, nothing too satisfying yet, though. Where to put? - on sidewalls: this would only work with the open side facing the user (flashlight and PS in horizontal position) at the bottom of the sidewalls, as pulling upward is pretty awkward if not impossible. Downside of this method is that you would need a relative strong retention system, hindering quick access. The object facing down would be possible but this would mean you'd have to catch the item as soon as you loosen retention. Bad solution for a high stress situation. - on bottom of pack: this would make for very fast access, but somehow I don't like the idea of setting a potentially heavy load on volatile items like pepper sprays and Li-Ion lights every time I put the pack down - shoulder straps facing upwards: my most favorite solution. Adds a lot of drag though and not very subtle. The weight would also pull the straps down making it harder to put the pack on. Definitely need some stiff shoulder straps with this method How to close? - velcro flap: Quick and easy in,quick and easy closure. Very loud though, making it a bad choice for self defense situations. - fastex buckle flap: too finicky and slow for high stress situations - shock cord retention: enough retention with very quick access. Hard to add concealment, though. Do you guys have any ideas, or even better, existing solutions for this problem? I'd really appreciate some input.
