Their products are rugged, bright and a little expensive. If you are serious about caving it's great stuff.

Most of the gear we use is generic and interchangeable. This is the gear we like and wouldn't trade. Audio Glasses https://lemunaglasses.com/ *I have hearing problems and this company sent us these as a courtesy and have been very helpful.
