This is the extended "L" version of the Cumulus Quilt 450, cut for users up to 201 cm tall rather than the standard 185 cm. It keeps the same insulation approach as the regular model — 850 cuin Polish goose down at a 95/5 ratio — but with slightly more fill, 480 g against 450 g, to cover the added length. Comfort and limit ratings match the standard quilt at -1 °C and -7 °C, and total weight comes to 745 g.
Unlike the standard-length Quilt 450, this version is not cut with a differential shell (the outer and inner layers are the same size), which is a reasonable trade-off for a longer quilt since it simplifies construction and keeps costs down, though it means slightly less loft margin than a fully differential-cut design. Packed size runs to roughly 25×17 cm, about 5 litres. It is aimed specifically at taller hikers who find standard quilts too short and need genuine shoulder-season warmth without hunting for a custom-made bag.
