Hand-Made, all Leather lace in hat liners for low vein Mining Hats. They can also be used in just about any Mining
Hat.  Liner has tabs the length of the liner made with leather making it line up with the holes in the hat no need to drill any holes in the hat. Liner does come with laces for top and bottom. Request size in messages to seller at checkout. I have the vinyl liners listed also.

Tabs and liner are made with 100% leather cow hide. 
  
How to get the size you need: measure around your head and that is the size you will need.  Example: your head measures 25" around (where your hat will sit on your head) you would need a x-large hat liner.

The sizes are:

Small--22 1/2"
Medium--24"
Large--24 1/4"
X-Large 26 1/2"

Request size in the Message to seller at check out.  Colors may vary.

Each has an adjustable Velcro strip in the back that will tighten or loosen up to 
1 1/2".
I have been making and selling these liners for over 10 years and no one has had any problems with the workmanship of the liners. If for some reason liner does not fit I can issue refund or can make one to fit your hat.  My husband has had one in his hard hat for over 2 years and still wearing it.

Please feel free to ask any questions you may have.
