I’m actually having a hard time finding a shot the ABU rain gear liner that I was issued… closest I’m seeing is the pic below, but that thing actually looks decent.
Ours was a material that looked similar to that, but shaped more like a vest - nothing went over our arms. It was completely nonfunctional outside of the actual raincoat shell though - you couldn’t just wear like a vest or put it under the ABU top for a little extra warmth. It was cut in a way that it’d just fall off without being buttoned into the shell.
…I wonder if there was some supply issue, and the ones we were issued were a shitty backup. /shrug.
