Gold Bond comfort powder is excellent for keeping you dry and comfortable. Use it around your neck as well! Some use corn starch but that's not a good idea since it's a food that would (feed) promote the growth of bacteria in moist areas. The comfort powder definitely eliminates the 'stickies'.
If you can afford it then "Gold Bond" is first choice but regular Talcum powder or baby powder will suffice. Discount stores have better prices for that product.I don't know what you have nearby but we have "Family Dollar" and "99 Cent Store""
