In reply to Tigger:
Many other brands use ethically sourced down for their bags(and clothing) including Alpkit.
Mountain Equipment, Berghaus, Rab, PHD to name just a few of the big names.
But on the original question, the Alpkit shout is a good choice. A little dearer these days (well does anything get cheaper?) abs as ever dependant on their stock.
