The Good: Great hard shell protection, they hinge above the elbow so they move WITH your arm, three straps that keep them in place without cutting off the circulation, can wear with or without a jersey, they are R and L specific so they are even more molded to your arm which helps them stay in place
The Bad: Very expensive for elbow pads but they are Dianese afterall, they don't cover all the way down to the wrist like some elbow pads do, the sizing is very weird on them so make sure you try them on before buying (again because they are made by Dianese and all their products are sized funny)
Most body armor jackets that I have worn seem to have great protection except for the elbow pad part. So to try and remedy that one year I used a body armor vest and separate elbow pads to keep things lighter and hopefully improve the fit since most jackets that combine the two don't work that well. After looking around and testing out some different models I went with the dianese since they seemed to fit the best without having to wrench down on the straps and cut off circulation like most pads required.
What I love about these pads is that they really do stay in place even though there are only 3 straps, they don't used the sock method like some other elbow pads out there. These three straps also keep things open and lets the air circulate more which stops you from sweating and keeps things cooler overall. What I hate about them is that they are very expensive and for some they won't be worth the money but if you are looking for the last pair of elbow/forearm pads you'll ever need then look no further; your just gonna have to shell out for them. The material is pretty thick which aids in crash protection and lets face it 9 times out of 10 when you go down you put your hands and arms out to break your fall so why wouldn't you want something there to keep you from smashing your arm on a rock or tree.
