The design of the Feathered Friends sleeping bag is a simple tube, or an elephant’s foot design, which you pull over your legs. Your belay parka, with its insulating hood, completes the kit and you are ready to sleep the night away under the stars!

Unlike other elephant bags, the Vireo liberally extends up over the shoulders, providing additional core warmth. But instead of consistently filling the bag with head-to-toe down, the Vireo lofts its horizontal baffling with a variable amount of down, providing “just enough” warmth where you need it most.

Since the torso overlaps with a parka, potentially repetitive down-fill is limited. The torso is filled with down rated to 45˚F while the foot box and legs are rated to 25˚F. The upside is flexibility. Use the bag alone in warmer temperatures. Bivvying in cooler temps? Simply pair the bag with a warmer jacket. Clean, simple, minimal.

The downside? Less fill in the torso potentially exposes the hands to cooler temps. For bivvying in downright cold temperatures, you’ll want to wear a pair of gloves or plan to stuff your hands in your pockets.

While the sleeping bag may be a bit more costly than others of its class, the Feathered Friends Vireo Sleeping Bag does use one hundred percent (100%) certified down, and has done so since 2015. Because it is certified, consumers can track the down in this sleeping bag through every step in the production cycle, from start to finish.

You may wonder if your sleeping bag needs such a high grade of care in its construction and to that we have to say we respect a company that thinks it is important enough, that their consumers are important enough, to get it right the first time!
