I've been mulling this idea over for a long time now, and I'm still trying to decide how I like these. The last couple years I've stopped wearing SteepleJacks in favor of my Gene designs. I think mostly that the baggy pants interfere with driving a clutch. There are however, several things about Jacks that I do enjoy, so I've been trying to combine the best of both worlds. These have more structural components of Genes, like the back yoke, an articulated knee (I'm still trying to decide if that bit is necessary with the flexibility the cuffs add, but it looks great) crotch gusset, etc. It also has baggier pant legs (but not as baggy, a compromise), cuffs, and the bamboo fold pockets that Jacks have.
I'm also trying to think of what to name them... maybe Jaques? Though I'd take a Germanic word over French any day.
These ones I made as winter pants, so they're made of a heavy wool fabric with cotton twill for the contrast fabric.
