Footnotes :

(1) the filling is WHITE, Polish, 'diamond grade' super goose down, whose Fill Power rating equals 870 cu in.

(2) the FILL VOLUME is a measure of the TOTAL insulating power of the sleeping bag

(3) the main part of the inner is made from graphite Pertex Ripstop Microlight fabric, but critical areas (ones that may get wet in extreme conditions) are made from the same Endurance fabric as the outer. These include the hood inner, and the sections around the feet.
