The aikido gi and aikido uniform you choose says a lot about you. They must be good quality to withstand the impact of regular training. If you buy cheap training aids, they will not stand up to hard consistent practise, so it is vital to get the best.
I know, because I have used cheaper aikido suits in the past and they just don't last. Over time, they lose their ability to protect you and start to look dull and lifeless.
It is important that your aikido uniform looks good, clean, and fresh, just like your techniques :)
