Yesterday I was informed by a European facebook hammock group, that the polish brand cumulus, who are known for making high quality sleeping bags which you can customize by inquiry, have started making both TQ's and UQ's for hammocks. They range from rated temperatures of +4c to -22c.

They seem a bit narrow looking at just their specs but are otherwise proper made with differential cut and H-baffles. I haven't seen any reviews yet, but I encourage people to link to reviews here
