Kilo TT has rack braze ons so you should not have a problem installing any rack you choose. I am using this combo:

Works for me but there are a lot of options to choose from in racks and bags/panniers. I lived in D.C./NOVA for a year and the summer was brutal especially with the humidity so you will sweat with a back pack on but there's also the aesthetics because some people think racks and stuff don't look cool. I'm 95% car free so I like to be able to run errands and get groceries etc on my bike.
