I have yet to try them on their own but they make great stuffers. I used some velcro strips cut off some pullups cause i take the sides off to use them as stuffers. The tri core is fun and way different than Im used to and they are incredibly thirsty. I doubled them under an M4. The first time i tried it i didnt rip the sides up to the top 2 inches of waistband, i wanted to see how the velcro would hold on the lower band. It holds very strong! This current time i ripped the sides to the top 2" and secured it w velcro and there's much more room for the boys and the combination doesn't cut into my thighs. Try them doubled, try them as stuffers, yet to try them on their own. They are greater than the sum of their parts with something else but alone im sure they fall short.
