The best ones I've used so far are the metal Kingston ones. They can
survive being on a keychain inside of your pocket without any kind of
issue. Using Bitlocker, you can also encrypt them for the additional
security you desire. There ARE military-grade ones which come with
encryption but you'll pay a lot more for them.

I've got a fairly cheap 4 GB thumb drive, dating from a time when 4 GB was
*huge*. And it still works perfectly although I keep it on my car keyring
(so I can never forget it if I visit anyone), so it lives most of the time
in my pocket next to all the keys on the keyring. The only modification I
had to make was when the mounting broke off soon after I got it and I had to
drill a hole through the case to thread the keyring through. That
modification, and the memory itself, has lasted probably about 10 years so
far. It gets written to and partly erased whenever an installation file for
a program gets updated (I carry around me all the free software that I
install for people - Firefox, AVG / Avast antvirus etc - to avoid having to
download it over their possibly very slow internet connection).

Every USB key I've ever owned has had that cheap plastic part which
allows you to keep it on a key chain break regardless of whether it
was on a key chain or not. Only this new metal Kingston one manages to
keep its shape. It's also a good 128GB and fast so I can't complain.
I'd recommend it to anyone.
