The main benefit of wearing training pants over regular underpants is that if the person has an accident, they do not soil their environment.

[3] Many toilet training pants use flexible sides for the wearer to easily pull them off and on like normal underwear.

Also unlike normal diapers, the sides are sold already fastened with the goal of enabling wearers to put them on independently.

Conversely, the sides may be more vulnerable to breaking and are liable to lose the psychological benefit of moving away from diapers.

Many companies have allowed a fairly large amount of absorbency in their pants, mainly to make them appropriate to be used for night trainers who wet the bed.

In addition to the visual wetness indicator, some companies have gone as far as to introduce a liner inside their training pants, specifically in the area most frequently urinated.
