As an American who drives a truck, this is moot. I have a full set of clothes, winter outer wear, a jug of water, a canister of peanuts, a blanket, a shovel, trauma sheers, a leatherman, a sun hat, to walking poles, a Midwest level scraper/brush, an air pump for my tires that plugs into the lighter, full spare, spark plugs, an extendable magnet, 10k lumen light that plugs into the cigarette lighter to charge if need be, tweezers, nail clipper, eyeglass repair, a paper book of maps for all 50 states, and a spare toothbrush.

Probably forgot some things. My truck is essentially my purse.

Uhhhhh.

Keys, wallet, and phones. Is all I do. Unless it is actually winter then I have gloves too.

Phone wallet keys.

There’s an umbrella in my car but I use it like once a year.

It really depends on mode of transportation, especially if a car is involved or not. I suspect a number of people in this thread are folks who drive most/all places and aren’t including all the stuff they have stashed in their cars, available if needed. Also, driving means minimal exposure to the elements, so even less stuff is needed to stay comfortable/presentable than if you are walking, biking, waiting at transit stations, etc.

As a former Tokyo resident I’ll also add that I used to carry a folding fan around with me in summer when I lived there, but I have no need in the US where air conditioning is so prevalent (to the point of overuse). I also stopped needing a fan so much, regardless of temperature, when living in less humid places.

Also, shocked more people aren’t mentioning a water bottle. I bring a reusable water bottle with me any time I have to leave the house for more than a couple of hours, especially if I’m cycling somewhere but even if I’m driving. How are y’all staying hydrated sans water bottle???

Most of the stuff I carry have already been mentioned so I’ll just add the ones not a lot of people carry:

• hand sanitizer
• a small travel vial of liquid soap
• a couple of squares of toilet paper rolled up

All of those including the standard phone, keys, wallet, etc. all fit in a small handbag that I wear across my chest.

Sometimes if I know I’ll be out in hot weather, I bring water in an insulated container. I also have a small bag that specifically has a pocket for water bottles.

Phone, wallet and keys most of the time, plus backpack with rain coat and water bottle if it’s for an extended time.

Keys, wallet, phone, shopping bag. That’s it.

I used to live in the desert. So on me, water bottle and sun block. In my car, water and a blanket.

The clothes I’m wearing, wallet, phone (sometimes a second), and usually keys as well. Depending on outdoors or not, sunglasses.

Unless I’m doing something specifically the would require more, that’s about it.

Phone,keys, wallet generally. If its going to rain I bring an umbrella. If its hot I put in cream. If im bringing a bag I bring a bottle of water

I wear pants, and shoes. Sometimes a jacket. If the weather is bad enough to require more than that, I stay home.

Keys, right pocket. Wallet and phone, left pocket.

Done.

Keys (house, car, bike), phone, wallet,… swiss army knife, handkerchief.
And during the pandemic a fabric face mask.

It all fits in my pockets

Then dependent on the weather I will bring sunglasses or an umbrella.
I check Buienradar (Dutch rain forecast app) to see whether I’m going to need that.

And sometimes, depending on what I will be doing, earbuds

I always carry a water bottle with me, no matter what the situation.

In a daily outing bag, I also always carry bandages, Vaseline, nail clippers, pepper spray, phone, glasses cleaning cloth, a portable charging bank/handwarmer, and a small stuffed animal (for emotional support).

I should start carrying sunscreen, but I 100% always spill things in my bag— be it ink, drink, or anything else.

For anyone reading this: purchase an Owala water bottle!! I don’t recommend brands often, but as someone who used to be chronically dehydrated AND always spilling shit: get an Owala. It has a lid that opens with a button push, a very good carrying handle that doubles as a button-guard when down, an easy to clean lid with removable/replaceable parts, and you can choose between swigging it or sipping it up without a straw!! I hate putting my mouth on straws, so that was a great option (even though I only swig lol— but the straw is inside the waterbottle). I’ve had mine for 2 to 3 years now, and apparently they’re popular now. Seriously, 100% recommend them. Only real downside is they are a bit too large for some cupholders and they can’t hold hot liquids, but that’s it.

Stay hydrated.

I have a “mom” sized pocketbook that I carry around and it always has the following:

• Band aids, nail clipper, and aquaphor tube
• Eye drops
• Wallet, phone, keys
• Masks
• Earbuds
• Hand sanitizer
• Sunglasses
• Small fidget toy
• Folding hairbrush
• Hair ties
• Small sunscreen stick, chapstick
• Pen
• Set of plastic cutlery
• Pill case with some commonly needed pills like Tylenol, Claritin, etc

If it’s sunny I’ll bring a sun umbrella and a hat, both of which can fit in the bag in a pinch. If it’s raining, just the umbrella. It’s not a perfect system but some things (especially the band aids and fidget) come in handy pretty often
