I'm not little. I'm 6' 1" and 330LBS. This carrier accommodates my LVL III+ AR500 armor (11"x14") as well as trauma pads and still fits over my job shirt. The MOLLE is well divided and sown with just enough slack to allow proper fitting of pouches. The VELCRO holds really well, maybe a little too well. Donning the vest is a little slow because you are fighting that VELCRO hold but once you have it adjusted you only have one half of the cummerbund to don or doff.
I am a paramedic and need a vest that I can don when the situation requires that level of protection. This carrier fits the bill!
