Hmm....interesting to see SD using cuben. I'm not quite sure they have the panache to sell a tent at that price level, but I'm glad to see them dabbling with these materials.
The design looks very similar to the Big Agnes Fly Creek UL2, with the main difference being the externally located poles. It's nice to see the poles located outside the fly to allow a 'protected inner' setup. Like the Fly Creek tents, I imagine the doorway is a problem area with the sloped door allowing rain to fall into the tent (likely) and the long vestibule likely being a big stretch to fully close.
I'm not sure what's up with the extra fabric at the sides - perhaps they're intended as extra vestibules you can slip some gear into? They look a bit small for this....the tent fly looks like it was accidentally baggy so they guyed it out. Tough to judge from one pic though.
$1800 is too much for what this is. People will easily spend $1800 on cool camping gear, but $1800 seems out of line for a cuben + carbon tent. You can get full cuben tents for $600 or so (ie. SMD Haven, Lightheart etc) plus a few hundred extra for carbon poles. I think Big Sky was selling their cuben Mirage tent for $1000 with full cuben and carbon poles.
