I know the general consensus when washing and drying a 100% cotton gi is to wash it cold and hang dry. But to me sometimes it's not practical to hang dry because I live in an apartment building (no direct sunlight when I hang dry my gis) and it's usually humid, which means a GI can take as long as a day and half to dry. Not only that but after a day of being damp, it can start to smell moldy. So lately I've been tumble drying my gis and so far they haven't shrunk any more than the initial shrink, and not to mention they smell much better. Am I shortening the service life of my gis by doing this?
