I think you would benefit from having a combination of treatments. We swear by our body glide product, but it may not be enough. Use the body glide during the day, and make sure to carry it with you so you can reapply it as needed. It will make the legs slippery, but if chaffing does occur, it will not help to heal the skin.
I think it is also a good idea to have something handy to treat any skin irritation. At night, we clean irritated, red skin well with an alcohol product like Sea Breeze. It really burns but kills anything growing on the skin and often helps to heal irritated skin overnight. After cleaning with Sea Breeze, it might be good to apply a product containing clomitrozole. It will kill yeast that loves to grow in hot, humid conditions. Carry the clomitrozole with you as well and apply it on any skin in moist areas as soon as any itching or discomfort begins.
My husband stopped having any problems anywhere by using these three items.
