It Ain't Always The Heat

I thought that, maybe, it was because I hadn't walked in the body armor in about 4 days. Or, maybe, it was the increasing heat. Whatever it was, today's walk was kicking my ass. I could barely take in a full breath. Halfway through, I realized that it was neither of these things exactly. I had adjusted my vest before the walk and made it too tight, and the chest plate wouldn't let my chest expand. So I took off the IBA, layed it out, loosened the straps, and it was better than ever. Now I could breathe again. That, and it was cooler.
