Not that other underquilts would be bad but i like the idea of supporting the 'local' economy. So far i only found the 'Underblanket' made by 'Snugpak' (e.g. http://www.ddhammocks.com/product/underblanket).
What other european based makers of underquilts do you know?
Right now i'm looking for a 3-season underquilt.. i'd expect it to work up to -5°C (23°F) and i'd like it do be as light as possible.
