Trekking: Double down with Sierra Designs’ Mobile Mummy 800

Sierra Designs Mobile Mummy 800 3-Season

Man isn’t meant to stay indoors — our weekly “Trekking” column can attest to that. It’s a column dedicated to the adventurer inside of all of us, the one pining to ditch the office humdrum for a quick surf session or seven-week jaunt in the Grand Tetons. One day we may highlight an ultra-light stove and the next a set of handmade canoe paddles. Life doesn’t just happen inside the workplace, so get outside and live it.

Sleeping bags should never be an afterthought. Whereas bags designed for car camping are crafted with comfort in mind, those intended for frigid nights in the backcountry are more concerned with minimizing the weight in your pack than a pleasant night’s sleep on the trail. However, with Sierra Designs’ Mobile Mummy 800 ($380), you don’t need to sacrifice warmth or protection just for the sake of your back and legs.

The versatile, 15-degree sleeping bag is snug, yet it’s two-direction center zip allows you to move more freely than is typical of a more traditional bag. A pair of zipperless arm ports allows you to read and drink your cup of morning coffee without having to fully embrace the outside world, while the bag’s stowable footbox lets you crack open the bottom and walk around without dragging the bag everywhere you go.

Most importantly, though, the three-season bag features 20D Nylon Ripstop and 800 Fill Duck DriDown — meaning you’ll stay warmer and drier in any scenario you might face. Its garmet-style design even allows the bag’s tapered build to rest on your shoulders instead of your head, even if the entire thing only weighs a mere 2¼ pounds to begin with. Plus, the draft collar, curtains, and tube ensure you retain warmth despite the plethora of openings. Now, just try not to confuse it with a Snuggie.
