Which maintenance practice is crucial for dry suit longevity?

Regular inspections for damage are crucial for the longevity of a dry suit. This practice allows divers to identify and address any wear and tear, punctures, or leaks that may develop over time. By thoroughly checking the suit before and after dives, divers can ensure that any issues are fixed before they compromise the suit's performance and integrity.

In contrast, other maintenance practices listed can be detrimental to the suit's lifespan. For instance, repeated washing with detergent can degrade the materials used in the suit, while storing it in direct sunlight can lead to UV damage, affecting the fabric's strength and flexibility. Additionally, leaving the suit wet in a bag can create a breeding ground for mildew and lead to odors, significantly affecting the dry suit's usability.
