My gis are slowly developing a perma-stank. I'll wash them with vinegar, as I've always done, but there's still a faint whiff of BO when I pull them out of the washer and put them in the dryer. It doesn't seem like a big deal, but I get to class and after about 5-10 minutes of sweating that odour magically turns into something as though I never washed it at all. The only time recently I was able to make a real dent in the smell I had to wash them twice in a row with a buttload of vinegar, but it's not practical for me to put them through two washes at a time because that's three hours of my day gone. I don't know what's causing it, but I have a few guesses. I live in a really humid place and over the summer they never really dry after class so there's a period of a few days where they fester on my pull-up bar instead of drying. Also they're soaking up a LOT more sweat between washes. I used to train for an hour most days, two hours on Wed and Sat. Now I train for two hours Mon/Wed/Sat and three hours Tues and Thurs. So, even though I wash them between wearings, they're soaking up 50-300% more sweat than they used to between washings. Any tips? It's getting bad.
