The Binding is outstanding -- the leather is soft, flexible, supple and liquid. It just feels good to hold it.
The Clarion is available in three binding options: A black Calf-Split leather, a brown Calfskin leather and a black Goatskin leather. You can read more about these options here. In short, they increase in softness and suppleness (and price, obviously) as you move from Calf split with Goatskin being the top level, softest and most supple. It's really something. Also the Goatskin and Calfskin have "art gilding" which is the red-under-gold look, and the Calf split just has regular gold gilding.
The paper is thin, but ghosting is minimal. My only quibble is that the pages tend to curl up at the edges in some places in the Bible. This has been reported in other places, however it doesn't bother me that much. I hope to be carrying this Bible with me for many, many years to come.
If you are looking for a "lifetime" Bible, this is a good choice in any of the three bindings. It is available in ESV, NASB, NKJV and KJV.
