good idea, bad in use
The full heavy lycra backside is a bad idea. There is too much friction between it and the saddle and it and the liner short = copious chafing of one's ass.
These are a great looking, light, comfortable shorts, but for considerable time in the saddle cranking out miles you're in for some pain. I gave these many chances with multiple liner shorts (the Gore Powers these come with are nice liners) and still same painful result.
For park use they'd be fine.
Sent mine back.
