You might consider this... I use black Tenas when out of the house unless on a long drive Then one up from that which are white. I have to carry a small over-the-shoulder bag with an injection supplies (steroid emergency kit). So it's in a small soft pencil bag (stands up in the back compartment), next to it I often have a Gatorade - can't get dehydrated or I might need the emergency kit). In the kit are 2-4 WetOne singles.. but a thin pack of wipes might be behind them.
In a quart freezer ziplock bag I put a spare black Tena (women only) - can hardly tell it's even a pull-up. I almost always wear pull-ups only very occasionally a tab brief to try out at home. It's a duel DL and UIC but def about pull-up. I also have the same setup in my computer pack pack.
So I like GoodNights (for kinda special times when need very thin or cute ones) but they are not very good at all vs Tena and cost more @ about $1.10 ea.). The Tena black is much much better. I wear women's tight boyshorts (like Brazilian boxer briefs) over them. Helps keep them in place. The Tena black are "stiffer" than the Tena white (which are nighttime) You can get the Tenas on Amazon for like $0.67 each in black they come two packs of 18 (sm/med) Some WMarts used to carry them but now they don't. I also have Tena 3-way cream which I always use. Good hand cream too. So, they even look like regular underwear. Always Discreet Boutique (about $1 ea but sooo soft and sex - my goto for sleepovers
) is another good one that is better than Goodnights but not to the level of the Tena. But they do have a nice scent to them and those channels. I only wear women's pull-ups becaue they just fit so much better, I enjoy them so much more and I used to wear bikini or boyshorts anyway -
If I need a spare, it's in the bag. (I have a small software lunchbox size cooler of spares (white and black tena, pack of wipes, small refillable bottle of the Tena lotion just in case). I have occasionally found myself without a spare so I hind a couple in the tire well from myself just in case) I have gotten more anxious about not having what I need so I kind of overcompensate with like 10 in the bag.
Since you like pullups and the black kind of looks uni-gender, no one would know or care if you were wandering around a locker room in them on and nothing else. I know because I wear them to the gym. No one knows.
You def have to have your spidey sense on in FL. :-( I imagine initially it feels like all eyes on you. I've felt that way. I'm sort of middle of the spectrum genderfluid so... I am a bit more careful lately in public.
But I've changed in the car out of necessity many times and aside from throwing a towel over my lap, never gave it much thought. I don't were very fem clothes (no skirts) in public but tight women's stretch jeans. Can't see the Tenas under the jeans. NO ONE is going to give you any trouble changing even if they did notice. It is a bit more cumbersome to change a pull-up in a public restroom because I have to take of shoes and undies and be barefoot in the bathroom. Oh, I usually have a large dog-size doggie back in my pack too. To put the old one in. Also black.
I'm going to Rene Faire next weekend and it's a long day so been wondering. Was to go to an air show Sun but we skipped it. People were trapped in their cars for 3-4 hours on sat and had to go #1 out on the side of the road (no trees here) sooooo.. I wasn't up for that - rained anyway. (we both wear now... my partner had some issues being addressed medically and then decided how much he like the girl's (generic) pull-ups and he loves me in them. He likes them really fem generic fluffy white.. More just DL.
