Twisted Veins ACHB50 15 m HDMI High Speed cable with high-quality fabric jacket + angle adapters and Velcro cable ties (version Latest supports Ethernet, 3D and Audio Return) (Electronics)
The high quality of this cable with an extremely tough casing makes it a perfect "outside-cable". As already mentioned, it is pretty solid, but can be up to a certain extent also bent, ie it keeps bends and does not return to its original shape.
