The Rab Continuum at the summit of Mount Washington in January.
The jacket is extremely comfortable, large enough to fit a few layers underneath but not so large you look like a marshmallow.
The helmet-compatible hood is very large when worn without a helmet, though it can be cinched down.
Hiking in wintry conditions in the Rab Continuum.
I almost always wear the Continuum under a shell jacket to protect it as the Pertex exterior is somewhat delicate.
The waist hem has a drawstring to keep out updrafts.
The Continuum can easily be packed into its small included stuff sack.
The entire jacket packs down to the size of two Nalgenes or grapefruits, making it perfect as a backup or emergency layer.
