Overview

A wave-construction top paired with a blanket-construction bottom gives this Marmot bag its loft. SpiraFil synthetic insulation fills it, and a footbox, a two-way zipper and a fold-down secondary zipper handle fit and venting.

Synthetic fill is the reason to look at it: the seller says the insulation stays warm even when things get wet. That makes it a good match for rainy trips. The limitation is that the rating appears only in the model name, with no scale.

Who it's for

Women who camp or trek in cool, wet conditions and want a roomy footbox suit this bag. Hikers who count every ounce or sleep in deep cold should look at lighter or warmer designs.

Pros and cons

Pros
  • Synthetic insulation for damp nights
  • Two-way zipper plus vent zipper
  • Stuff sack included
Cons
  • Rating shown only in the name
  • Temperature scale not stated
  • Left zip only in this size

Performance notes

High-loft synthetic fill holds its shape when damp, which is why it is chosen for wet trips. The wave-construction top and blanket bottom are laid out to maximize loft, and the secondary zipper lets heat out when the bag gets too warm.
