In reply to bouldery bits:
If it’s only a month ago they disappeared as eaf4 said, it could be worth a few phone calls to larger retailers who previously stocked them?
I wanted a specific Rab top two years ago quite a long time after it was discontinued and out of stock everywhere online. However, I found three available (one in each of three different sizes) at one retailer which weren’t advertised at all but just held in their end of line stock.
When I initially asked the reply was no, none, out of stock, sorry, but after a chat about how I liked them and that I would definitely have bought one if they had my size left, within five minutes they had come back to me saying they had one in my size. Sometimes stock control errors, as in my case, makes them invisible in the system without someone checking manually.
