Hand warmer pockets are the standard front pockets at hip level on snow pants, and they're one of those features you don't appreciate until you're freezing on a chairlift without them. They're lined to trap heat and keep your hands comfortable between runs, which makes a real difference on cold, windy days.
Fleece-lined versions are noticeably warmer and cozier than basic nylon or mesh linings, so if you ride in cold conditions often, they're absolutely worth seeking out. Also, pay attention to pocket placement—some sit higher or lower on the hip, which affects how easily you can slip your hands in while seated on the lift. It's a small detail, but it can change how comfortable your whole day feels.
