I had to get them custom made on Etsy. $45ish each, but 100% worth it. I highly advise against most synthetic fabrics, though.
I have some micromodal ones that are nice, but nothing performs like wool. I'll take them off at the end of the day and they'll be wet from sweat, but my skin is dry.
And that's saying something, because I have hyperhydrosis.
It's also forgetting that a significant portion of homeless people are homeless by choice, or are homeless for reasons that just providing housing won't resolve.
People have this idea that all homeless people are just regular people who experienced hard times, but that's just a minority. Most homeless are mentally ill people who won't take their meds or drug addicts who aren't willing to quit.
It sucks, and they shouldn't have to live on the streets, but you can't force people to change.
