Compresses down to water-bottle territory in your pack.
A 650-fill duck down mummy bag in four fill weights, so you buy exactly the warmth you need: SP400 for September and October, SP550 for cold sleepers and late fall, SP700 and SP1000 for winter camping and hot tents.
Buy by the comfort rating, not the limit. Down is not machine-washable: spot-clean the shell and sleep in a liner; wash rarely with down detergent and dry with tennis balls.

FAQ
By the coldest night you expect. SP400 (comfort 3.8 °C, 0.86 kg) covers September and October in southern Ontario. SP550 is the safe choice for October and cold sleepers. SP700 and SP1000 are winter bags for snow camping and hot tents. All four are the same 205 × 80 cm size and the same 650FP duck down; only the amount of down changes.
Comfort. It is the temperature at which an average sleeper stays warm all night in base layers on an insulated pad. Limit is curled-up-and-coping; extreme is survival. If you sleep cold, go one model warmer than the comfort rating suggests.
205 × 80 cm, comfortable to about 195 cm tall.
Rarely. Spot-clean the shell and sleep in a liner to keep the inside clean. For a full wash: down detergent, gentle cycle in a front-loader, then tumble dry low with tennis balls until completely dry.
You get 650-fill duck down at 85% down content in a 20D shell with a YKK anti-pinch zip, the same construction as name-brand down bags, and you can pick the exact fill weight instead of carrying a winter bag on an October trip. Against a cotton bag with the same rating, it is roughly half the weight and a third of the packed size.
