Most of my shirts don't have pockets, long sleeves, or intact collars.

I cut open the front of my T-shirts because they're too small for my 19" neck, and I feel like I'm being strangled. But I did buy some work shirts and long sleeve T-shirts for camping and riding my ATV. When you're wearing something like a Carhartt or Dickies work shirt instead of a plain T-shirt it saves your arms some wear and tear, riding through the woods. I can put my Oclip in the pocket then pop it out and clip it on when I need it. I have an i1R 2 Pro flashlight on my key ring, which I just remembered to plug into my computer to recharge. It runs up to 12 hours at 5 lumens on a battery the same diameter as a AAA, but only half as long. And it's done charging already. I just had to top it off. I plan on using the Oclip a lot when I'm camping, instead of using a headlamp, but I have an 1,100 lumen Perun 2 Mini headlamp if I need a lot of light or more runtime. I don't think I've used my old headband light since I bought that one. It has a small plastic light that sticks onto a non-adjustable elastic headband.
