Down is traditional insulating material. In case that we
protect down against the direct humidity, there is no better filling
with such compressibility, low weight and high insulating ability.
In combination with modern fabrics it gives an option to make
very popular lightweight jackets, which are also called „down
sweater“.
Compare with conventional thermal layer, these jackets and vest
are more efficient and its volume and weight is inconsiderable.

Colibri DWR: 

Extremely light fabric especially designed for
equipment filled with down or synthetic filling.
Combination of low weight and high density
construction allows getting maximal loft with preserving
durability. Fabric has DWR finish which protects filling
against moisture and allows breathability as well.
