I have the KLIM Badlands jacket and pants. I love the jacket, even when it is hot. It vents VERY well. I have a Motoport Air Mesh II Kevlar jacket/pant suit as well. I find that when it starts getting really hot, like 95 and up. The KLIM is actually more comfortable. Both are hot if you are stopped. However, once moving, the KLIM flows enough air that even at low speeds it is comfortable. In fact, since I got the Badlands suit, I rarely wear the mesh anymore.
My beef with the KLIM is the pants. The knee armor moves all over the place and I think it needs better coverage for side impacts rather than just straight onto the knee cap. Also, I wish the pants had full length zippers, or at least up to the crotch. My Motoport pants have a full length zipper up the inside of the right leg and the left comes up to the crotch. This makes it very easy to put on and take off the pants without removing my dirt boots. With the Badlands, I have to put on the pants first and then the boots, or take off the boots first and then remove the pants. When camping, I don't always want to have to remove the boots just to put on or take off the pants. However, if they did better knee armor, I could live with the zippers as is.
I've worn my Badlands gear in 105+ temps here in East Texas and I was comfortable, as long as I was moving. A BIG factor in comfort will be what you wear under your gear. Jeans are going to be pretty hot no matter what. I like the moisture wicking under layers that pull sweat away from the skin. Then, when any wind passes over these layers, the sweat evaporates and feels very cool, even at low speeds. Of course, this is not real practical for commuting where you need to be dressed like a normal person when you reach your destination. If you are doing that, an Aerostich or something similar will be best because it will go over regular clothes the easiest.
