Based on the costume worn by Jor-El (Russell Crowe) in the 2013 film, the leather armor -- yes, that's leather -- features the mind-blowing detail we've come to expect from Lee. Note the intricate work on the "S" emblem ("On my world it means 'Hope'"), the layered shoulder pieces (I guess they're called spaulders?), and a helmet that looks somehow both delicate and formidable.
It's perhaps not the crowd-pleaser that The Joker and Iron Man armors are, but it's absolutely gorgeous. You can inspect the costume in hi-res on Lee's deviantART page to fully appreciate the craftsmanship.
