Caving kit bags

 The Kit Bag is a speleo bag. These bags are often also ideal for transporting small personal items.
Kit bags are often also suitable for canyoning and working at height.

For caving, a few basic bag types that are specifically designed are:

Side bags:
Side packs have two wide adjustable straps and typically five D-rings that allow the pack to be worn as a traditional backpack, fanny pack or side bag. The side pack configuration is the most popular and is a very efficient way to carry a pack through a lot of chimney climbing and crawling.

Tackle bags:
The standard bag used is a round or oval bag with two shoulder straps and a drawstring closure at the top. Most of the larger ones have a roll-top closure instead of the drawstring variant.

Waterproof bags:
These bags are often made from a urethane coated fabric that is extremely abrasion and puncture resistant. Another waterproofing option is to use a tackle bag with drainage holes with a waterproof bag inside. Alternatively, a barrel can also be used.
