My Nerd-tactical Gear B-)
(1) Samsonite Delegate II briefcase
(2) Marchon Flexon Glasses
(3) Insulated Kleen Kanteen wrapped in foam and hockey tape
(4) Perfect Digital Watch -- Timex Datalink, discontinued :-(
(5) Perfect Wallet -- Lowepro Santiago "wallet"
(6) Fenix E01 Flashlight
(4) Perfect Pen -- Modified Staedtler Marsmatic 700 with 000 sapphire tip
My pen and my flashlight are attached to the wallet, which is attached to my car keys, which is clipped to my pants. Haven't ever misplaced any of those things since I started doing that. (I used to have my cell-phone velcroed to the wallet, but no one ever calls me, so I keep it in the briefcase now).
