Sustainable Down Source is certified by the Responsible Down Standard

We offer RDS CERTIFIED regular and DWR down.

Through a very selective sourcing process, all SDS down comes from farms that undergo strict audit procedures to ensure that our product does not come from birds that have been force-fed or live-plucked.
