Scroll all the way to *almost* the bottom, and you'll see micro rigs. Arc AAA is there. I have several of the sheaths from Onscene. Very professional products.
I have the LS123 kydex holster with the metal clip. If you store the LS/123 in the holster with the lens facing out, you can clip the rig to the bill of a baseball cap (gimmie cap) and it makes a nice ARC Nerd CAP (headlamp)!
from the looks of that micro rig from the above website, i would be afraid the aaa arc could wiggle itself out thereby be at one with the ground. it appears its just a friction fit. but neat factor is there.
Yeah--Kydex is magic! Might "fall" out of you attached it to a helecopter propeller or something, but if you do that loosing your AAA is probably the least of your worries...
