Got a new set of T-shirts from supply to wear under my ACU's in Iraq. Wore without washing. Trying to sleep that night I thought sand fleas got into my bed, unbelievable itchy and crawly. One of the worst nights of trying to sleep in my life, pure misery. Saw medic the next day thinking sand fleas but nope, some chemical on the t-shirts. I wash EVERYTHING before it touches my skin now.
