Just spoken to the retailer Elite Mountain Supplies. He's out of stock of the UL7 and won't be getting another delivery until October. He said he'd checked with the importer and other retailers as well.
He's sending me a UL 9 instead, for 80% of the price difference between the 2 products.
I'll send the old one back to Lyon. I've already sent them an Exped pillow this week....
