How should I handle bathroom breaks while wearing compression hip shorts?

This is the most common practical complaint with compression shorts. You'll need to pull down both your ski pants and the compression shorts, which typically requires at least loosening your ski boots in a restroom. Some skiers plan bathroom breaks around lodge stops where they can fully remove layers. If this is a major concern, consider models with a zip fly front (available from some brands) or look into wrap/belt style protectors that are easier to remove. Most skiers find the inconvenience manageable once they develop a routine.
