Reddit mentions of Fury OC 18% Aerosol Red Pepper Spray Twist-Top with Safety, 4-Ounce, Stream

Great start! Feel free to x-post to /r/bugout, as they'll have some more suggestions. Here are my thoughts:

• I agree with gittenlucky: if the first-aid kit is mostly off-the-shelf, you may want to consider adding some pain killers, anti-diarrhea, and any prescription meds you might require. Some people also recommend iosat tabs, if you're concerned about nukes. If you're comfortable collecting and using them, also consider minor surgical gear, antibiotics, etc. Maybe some sun/bug protection? If you're walking, moleskin and foot powder?
  
  
• Although I noticed you have at least one pull-top food can, the P-38 can opener is lighter and surprisingly effective. If you're interested in lightening the load, they're available cheaply. Lighter than carrying cans, you might alternatively consider a stack of Datrex bars.
  
  
• While the candles might be romantic on a calm day, I'd swap them out for a flashlight, head light, or a pack of chemical glow lights. Each stick lasts about 8 hours and is pretty bright.
  
  
• Have you considered any defensive items, even if it's as benign as pepper spray?
  
  

OK, thanks for the advice. I'm definitely going to add the 550 cord. Pepper spray is another good defensive option that isn't banned in the People's Republic of Chicago. You've also sold me on the stainless steel canteen, so consider that and some water purification tablets added, too.
