Here are a my favorite brands for the best comfort:
Pink No Show Yoga Thongs. Very comfortable and the material is great for hard sweaty workouts. Also because they are made for yoga they material is very flexable. I fit into both mediums and smalls.
Underarmour makes some amazing underwear for working out I have 6 pairs of their Dri-fit thongs. They are by far my favorite and most comfortable underwear for all occasions. I have never tried the boy shorts of the bikini bottoms but my friend owns some and she says that they are just as amazing. The thongs are one size fits all. I am normally very skeptical about these kinds of szes but they fit me very well!
Also try the Victorias Secret VXS Thons I am told that they are perfect for any sort of work out.
Comfort and exercise go hand in hand.
