Be careful of thin plastic bags that tear easily and can spill the carbide in your cave pack or on the floor. Ample extra carbide or back-up batteries and bulbs for double the time you intend to spend in the cave. The following are optional personal items which may be carried on caving trips. Many experienced cavers consider these essential. Gloves with rough finish to protect your hands from cuts and keep them clean.
Knee pads can be very helpful.
Cave snack or lunch. Sandwiches hold up only if protected by Tupperware-type containers. Be sure to take all food and trash out of the cave when you leave. Sturdy carrying bag or pack. Small first aid kit.
