Snowbird Mummy SP400 Down Sleeping Bag
- 400 g of 650FP duck down
- From 820 g
- Down-proof 20D shell
The Snowbird SP400 carries 400 g of 650 fill power duck down from 820 g total. The 20D polyamide shell is down-proof, so the fill stays inside the baffles rather than working its way through the weave, which is where cheaper down bags fail. The mummy cut tapers to reduce the air your body has to heat.
Best for
Three-season hiking and camping, including cold autumn nights, where weight and packed size matter.
Not ideal for
Winter. At a comfort rating of 7 °C the warmer Snowbird models suit sub-zero nights better, and down loses its insulation once wet.
Additional features
- Available in Medium and Large, so the bag matches your height rather than carrying dead space
- Compression sack included for transport
- YKK zip
- Comfort, limit and extreme figures all published
