Reddit reviews Ripoffs Utility Combo Holster for Mini Flashlight, Knife, Plier, or Scissors CO7 (Side Clip)

I had similar issues, but in the IT field (squeezing through server racks, etc). For your specific situation, I would recommend a combination of:

• Any single-AA light from a reputable company, that comes with a pocket clip: Thrunite, Fenix, Zebralight, etc. Ditch the lanyard, it will snag.
  
• A super-sturdy tool pouch that is made for abuse. Your light will clip into the pouch, instead of your pocket. Ripoffs brand is my favorite, for reasons below. You can buy their stuff on Amazon, but use their main website to look up the model numbers. CO- is clip-on, and BL- is belt loop.
  
   
  
  A good tool pouch is critical here. Your problem is that the pocket-sized AA lights are designed to clip into a pocket or pouch, not directly to your belt. If clipping directly to a belt, the clip will get bent out of shape, or else it will squeeze itself off of your belt when the light snags on something.
  
   
  
  I like Ripoffs brand because they are super rugged, and designed for daily use in your conditions. The belt clip actually surrounds the belt, so it cannot be pulled off accidentally. I recommend getting a flat, open-ended tool pouch or electrician pouch, for easy reholstering. You don't specifically need a flashlight pouch- it can be anything with the right dimensions. Be wary of 'mini maglite' size, as it may be too skinny.
  
  Models that will likely fit your needs would be:
  
  
• CO-64 or CO-32, for just the light
  
• CO-7, If you want things covered and also have some space for wire cutters / pliers
