untuvalla

Untuvalla is a Finnish adessive form of the noun untuva, meaning down or down feathers. In Finnish language and product labeling, untuvalla is used to indicate that an item contains down as filling or is lined with down. It is commonly found in textile and apparel descriptions.

In practical usage, untuvalla appears in phrases such as untuvalla täytetty tyyny (a pillow filled with down) or untuvalla vuorattu takki (a jacket lined with down). The form signals the presence of natural down rather than synthetic insulation and is typically part of compound descriptions that specify the material or lining of a product. Because untuvalla denotes a material attribute, it is most often seen in marketing, packaging, and technical specifications rather than as a standalone noun.

The term refers specifically to down as a filling material. When down is mixed with other fillings, or when product labeling uses general terms like "down insulation," manufacturers may use different Finnish formulations (such as untuvaa sekoitettu or untuvainen) to convey the exact composition. In Finnish and EU labeling practice, the use of such terms helps consumers identify the type of insulation and its quality, particularly for outerwear, sleeping bags, and bedding.
