Is caused by body parts rubbing together or body part rubbing against something. Moisture and bacteria are chafing allies. So stay clean and dry and chafing will be reduced.
Body glide, Gold Bond creme and powders, etc----they all work.
Depends sort of where you are chafing and why. If thighs are rubbing together and chafing, then a pair of nylons or cut off long johns or biker shorts can prevent that.
Some girls chafe in the breast region----tighter fitting sports bras and various lubes help to prevent this.
If chafing in buttocks area, clean the area and keep it dry and use lubes. Skirts and kilts are good ideas. Good air movement helps you stay dry. Don’t wear anything underneath which will hold moisture.
And yes chafing is a common problem. It has ended many a hike and thru hike. It is similiar to blisters, one it starts, you had best treat it immediately, else it will just get worse and worse as time goes on.
See you out there.:cheers :cheers
