I own and love several Tom Bihn bags, but would often find myself with 'analysis paralysis' when trying to decide which one bag would best suit the load that I needed to carry on a particular day. I also hated having to transfer my stuff from one bag to another. So, inspired by the YouTube videos of The Urban Prepper (http://www.youtube.com/user/TheUrbanPrepper) I created my own, basic, Tom Bihn based, tiered EDC system. Which, without further ado, I present to you now in all its Burnt Orange Glory .....
OK, no bags and no Burnt Orange just yet ..... Just my keys, a teeny tiny Streamlight Nano torch and a Leatherman Style. These are always in my pocket so that if I happen to step outside the front door to chat with a neighbour, I'm not going to accidentally lock myself out (learnt the hard way!! )
Tier 2 = Tier 1 + :
Small Cafe bag containing (roughly left to right from top to bottom) folding shop bag, little screen wipe thingy, manicure set (trying hard to grow my nails after 40-odd years of biting them!), card wallet, sunglasses, store loyalty cards, spare AA batteries, Snow Peak mini spork & travel chopsticks, Joby tiny tripod, emergency battery pack & cable (in pouch), folding reading glasses, hand sanitiser spray, tissues, pen, penlight torch, (not pictured) iPhone, iPad mini, earbuds and folding cap. I also need to add a small first aid kit and have a double organiser pouch set aside for this purpose. I will carry this bag whenever I step outside the house for more than a few minutes. I use a 3D mesh organiser pouch to corral the small bits and bobs that wont fit in the front or internal pockets of the cafe bag. The dark interior doesn't bother me in the slightest because everything is kept in the same place and can be easily found without having to physically look inside.
Tier 3 = Tier 1 + Tier 2 + :
Depending on what else I feel the need to carry, this will either be my S19 or my S25 (or, soon, my Daylight Pack ). I will take this whenever I'm going further afield, out for an extended period or if the weather dictates. It will always contain a water bottle and a waterproof jacket but may also carry extra clothing layers, food, headphones, laptop in Cache etc etc. The Cafe Bag can be nested inside the backpack but I usually carry it separately for easy access to its contents.
A couple of weeks ago I went on holiday (car trip) for a couple of weeks. I took my S25 as my 1 travel bag. With my clothes packed into Pilot packing cubes, they were easily removed so that the S25 could also double as my Tier 3 on our days out.
