Thor Quadrant Protector 4.7 5 3 3
Great product for the money I'm very happy with this product. I'm 5'10' and weigh 250. This protector fits me very well and is comfortable enough that I forget I even have it on when trail riding. I've tested it by hitting the ground a time or two and I'm very happy with the protection level. It has good airflow and good looks. I would recommend this product to anyone. June 7, 2013
Solid protection. This thing is pretty solid, and pretty big. I like the monolithic tank-like angular look. It's a one-size-fits-all kind of deal, but it fit me quite well nonetheless (5'6", 175lb, long torso/short legs, stocky build). It's nicely curved, so it goes around the side of the body nicely. It does put pressure on the shoulders when wearing a camelbak, but I'd expect that's normal. The padding seems adequate, and the airflow is good (comfortable during recent 100 degree Lake Pleasant, Arizona desert ride). I wore it on top of a thin mesh hockey jersey to stay cool. Very easy to put on. Bicep guards seem somewhat unnecessary, but when the straps are tightened they stay in place. September 26, 2011
