I have loads from John Lewis. In my experience they don’t shrink or fade and last for years. https://www.johnlewis.com/john-lewis-supima-cotton-jersey-crew-neck-t-shirt/navy/p6030384

I’ve been hunting for a radar app as good as Dark Sky ever since it was discontinued, but not found one so far. Currently I’m using Ventusky (on Apple) because it provides a lot more detail than rain radar (wind gusts, air pressure etc).

I wondered if it might be something to do with the real name policy on Facebook. Instagram is closer to Twitter in not having such a policy.
