Just buy your own gi, then you can use that at which ever places you wish to train.

I train at a gym and they have a gi that people can buy, but I only plan on doing it for 2 months there because that is by my college and back home there is another gym I was planning on going to, but is that disrespectful to train at two places? Should i just get a normal gi if I am going to train at both? Please help
