Why we like it.
Very warm for its weight
750 g of 850+ fill power down gives a 14°F comfort rating and a 0°F comfort limit at 2 lb 10 oz.
Responsibly sourced down
The white duck down is certified to the Responsible Down Standard.
Heat-trapping design
A hood with adjustable collar and pull cords, plus shoulder and zipper baffles, block drafts.
Thoughtful extras
An internal pocket holds a phone or flashlight, and four small pouches hold heat warmers.
Packable
It compresses to about 13 x 7 in with the included sack, and a mesh sack is included for storage.
A few things to consider.
Mummy cut is snug
The mummy shape is warm and light but gives less room than a rectangular bag.
A cold-weather bag
With a 14°F comfort rating, it is more bag than you need for mild summer trips.
Down needs care when wet
The shell is water resistant, so keep the bag dry and store it loose in the mesh sack.
