For us in the northern hemisphere, winter is coming. Temperatures are dropping, and for most of us that means clothing changes.
If you carry some sort of self-defense tool: gun, taser, pepper spray, knife, whatever (and maybe you carry a combination of those), can you still access that tool quickly and effectively with your change of clothing?
Are you wearing more layers of clothing?
Are you now wearing a heavy coat? That you close?
Are you wearing gloves?
Take some time to practice with your change in attire. Make sure it all still works for you.
