I have both. However, sealed should always be resealable while in the field, especially living in the wet PNW.

I’d picked up one of Doug’s PSK’s shortly after they came out and about a year later when out checking for windstorm damage on fences used the wire to jerry rig rather than walking back to the barn. While I replaced it --it was time consuming finding the exact gauge and then re-rolling it neatly. So shortly after that I decided to pick up another PSK and always leave that one totally intact for an emergency. That was really a good idea as it gave me the opportunity to actually practice with the signal mirror, compass-comparing it with my regular compass and fire making tools when out and about on my small farm and leaving the other kit always totally intact for when I leave the pavement for a hike.

That’s also given me the opportunity to play around with some other containers. What didn’t work for me was trying to stuff too much into a small waterproof hard-sided container as things were going to either get wet or spill out and potentially be lost when opened and especially when trying to dig something out of the bottom. So I keep the original pouch and then usually put that into a larger but still pocket able pouch or waterproof container that is often combined with the shelter or FAK supplies. I’d caution trying to play around with reorganizing Doug’s kit too much as that kit has a whole lot of lifesaving thought put into it. Supplementing it some is fine but I can see the need for most everything else, maybe with the exception of the fishing supplies.

With all my kits, first aid kit included, I keep a small light packed near the top so it is easily accessible when the kit is first opened. So yes, there is some redundancy but light is pretty darn important if lost in the woods in the middle of the night and I‘ve always had a theory that FAK‘s should be self-contained. I’d highly recommend either the nano or Doug’s pico over the photons for two reasons-- the photons can get bumped on and the batteries would be a nightmare to change in an emergency situation out in the field, too many little parts that could get lost. The photons are great little key chain lights, however.

Along with having a psk on my person, I also always include additional shelter in my pockets such as the AMK Heatsheet or Bivy and a small FAK. I’ve supplemented Doug’s original kit with 4 Katadyn water purification tabs, a one quart freezer zip lock bag, a small Steamlight nano light and a few BCB lifeboat matches with striker. While I don’t yet have a small knife in that kit, I always carry a knife, leatherman, good flashlight, bandannas, a couple of bic lighters, whistle, and cell in my pockets.

In the summer I almost live in the Filson Tin Cruiser vest which has ample large pockets. And I just don’t buy winter outerwear unless they have has sufficient pockets that will accommodate my various kits. And sometimes that takes some shopping as clothing made for women are notorious for scrimping on quality large secure pockets.

The main thing is if you’re going to get into your emergency kits -- then you had better promptly replace the items used or damaged. I’m lucky that I have several outdoor stores in my immediate area that carry replacement supplies for both PSK and FAK. So if your back is hurting and you use the aspirin then promptly replace them. Most people don’t and that becomes the problem. I find myself getting into the FAK’s for aspirin or a band aid but not the PSK so much, as my regular gear is used rather than the PSK.
