You probably know this already, but Marmot makes really, really nice sleeping bags, especially the down bags. Honestly, it’s hard to go wrong with any of them! That said, there are so many different Marmot down sleeping bags, it can be a little confusing to browse the selection. Which fill-power of goose down best fits your needs and budget? Are you looking to save every gram, or do you need a waterproof shell fabric?
It’s OK, we’re here to help. First things first: goose down is rated by fill-power; the higher the number, the more efficient and lofty the down is… which means achieving the same temperature ratings at a lighter weight than lower-quality down.
Second, as of 2014, all Marmot goose down bags except the MemBrain bags (which feature a waterproof, breathable shell fabric) feature “down defender” technology, a coating that helps the down stay lofty and warm when damp.
