I carry an ARC AAA Premium.It is AAA but I get elevin hours of full light with a new battery.It carries in the pocket well and the head turns a little stiff.I will also second Hikermor on Fenix products and Gerber Infinity.Have three Infinities (car,coat and work)and had them for YEARS with no issues.The Fenix I have is an E01.Very similar to a ARC AAA and around half the cost.The ARC AAA is made in America and the Fenix in China if that matters....
