In most cases, no. D3O pads at 8-10mm thickness are virtually invisible under standard ski pants. The soft material conforms to your body rather than creating visible ridges or bulges. Only very tight, thin, or light-colored ski pants might show a slight outline. If discretion is a priority, look for ultra-low-profile D3O models specifically designed to be invisible under clothing. This is one of the primary advantages of D3O over traditional foam or hard shell protectors.
