Familiarity: I've put it through the wringer
My buddy tried a few different vests out and settled on this one for the Wasatch 100. He loved the minimalist, yet functional design and felt it carried the best on his frame. Enough pockets to carry his pill holder and chews and his jacket and layers comfortably fit in the back.
