So this has recently been something I’ve dealt with with all of my workout clothes (including my bike kits). I’ve been adding Oxyclean in addition to Arm&Hammer detergent to the wash and has really worked well.
PRO TIP: First time through, soak your smelly kit in hot water with oxyclean for 2-3hours. Then do a wash cycle on hot water with detergent and oxyclean. Once you’ve done the soak the first time, you should just need to wash and it should be good to go.
