These overall quality and construction of the Oxford heavy duty braces is superb, and far better than any other braces I have bought and tried in the past. The elastic straps are strong and also wide so they can be tightened right up and not dig in my shoulders, even worn over thin t-shirts. The metal clamps are strong, snap on tight and once attached stay put. The plastic liner protects the material of my riding trousers. It took a few tries to get the clamps in the right position, but once done they remained in situ. The metal adjusters on these braces allow them to be tightened and loosened really quickly, which is crucial for those impromptu toilet stops. Once the metal adjusters are set in the right place they stay there. Braces are essential with certain types of trousers, such as my RST textiles, and these Oxford heavy duty braces are perfect and highly recommended.
