With high temps and high humidity here in the southeast, I believe that this systems design is best suited. The construct seems to be plenty tough for regular outings on the trails and also during weight training days in a gym type setting. The padding is excellent and it seems like the weight is more evenly distributed higher on my torso which I find to be very comfortable. Additionally, the smaller individual weight blocks allow for excellent adjustable weight distribution that also conforms to my body better than flat plates. My buddies that have the backpack-plated versions are now wanting to switch over to this vest system.
