Dry suits can be inflated with air from the main cylinder or a suit bottle. A suit bottle is a specialized small tank designed to hold a limited amount of breathable gas specifically for the purpose of inflating the dry suit. This option allows divers to adjust the buoyancy of their suit without relying solely on air from their main cylinder, thereby reserving that supply for their breathing needs.

Using a suit bottle provides divers with greater control over their buoyancy and helps manage the air volume in the dry suit as they ascend or descend. This is particularly important for maintaining comfort and safety during the dive. The design of the suit bottle makes it easily accessible and convenient for use during the dive, offering a practical solution to suit inflation needs.
