Hailed as much more comfortable than your average mummy sleeping bag, the Nemo Nocturne 15 Degree Sleeping Bag by Nemo is shaped to accommodate the way most people sleep. An incredibly warm option, if you love car camping and the occasional backpacking excursion, this bag is most definitely for you.

Convenient Shape – LOVE IT!

Nemo Nocturne 15-Degree-Sleeping Bag by NemoProviding space where it’s most essential, the Nemo Nocturne 15 Degree Sleeping Bag by Nemo is wide in the elbows, tapers down through the hips, and flares back out again for optimal knee space. Compare that to traditional mummy bags, which taper around the hips and just get narrower. If you always sleep on your back, mummy bags won’t bother you, however if you’re a side or back sleeper like most, you’ll need a bag you can move comfortably in. This bag allows you to move and shift your knees comfortably as you snooze rather than waking you up because you’re twisted into some disastrous position. And while it works well if you’re average height or a little above, it’s a bit tight if your shoulders are on the broader side.

Additionally, the bag’s construction keeps the down from shifting about as you catch your ‘zzzs.

Warm, But Temperature Rating Is Off

Temperature rating is huge in regards to sleeping bags, as the wrong option will leave you shivering or sweating buckets. A 700-fill duck down bag, users consistently rate the bag as very warm, even in frigid weather. Created with “power down” and DownTek™ nanotechnology, the 15-degree rating is a bit ambitious, especially in light of the extra room down at the bottom. This decreases thermal efficiency–giving the bag a +-25-degree rating is probably more accurate.


The extra room at the bottom of this sleeping bag results in additional weight, and while the regular bag is 2 pounds, 6 ounces and the long 2 pounds, 8 ounces, this bag probably isn’t the best if you’re a backpacking ultralight extremist. As an avid backpacker, this is a bag I take frequently on my backpacking excursions. One of the benefits of mummy bags is how light they are, which makes them easy to strap on your back along with your other gear.


While most bird down bags are doomed if they get wet and take an extremely long time to dry, the Nemo Nocturne 15 comes with a waterproof coating on its back side. This coating works in conjunction with its Durable Water Repellent finish to protect the bag from tent condensation.  This bag pared with the Aqua-Quest ‘Single Pole’ Waterproof & Breathable Ultra Light Bivy Bivouac may be a match made in heaven.


The Nemo Nocturne 15 comes with a tuckable Blanket Fold™ hood. This insulated flap of fabric is meant to wrap around your neck to block drafts and keep you extra toasty, and is celebrated as one of the bag’s best features. The hood isn’t as comfortable when cinched via drawcord, but improves when left open. The fabric flap is therefore very helpful when you want to leave the hood open but don’t want to wake up with a stiff neck from the cold.

Additional features include a pillow pocket for stuffing clothing or a camping pillow in – yes I said “pillow pocket”. Why have I waited so long for this feature. I LOVE IT. There’s also a zippered watch pocket for your phone so you can hear your alarm come morning, and a roll-top compression stuff sack and a storage bag. The zipper doesn’t feature a velcro or snap closure, so if you’re 5”11 or taller you might work the bag open in the middle of the night. Should you be this tall or taller, look into the long option, or another bag designed for taller individuals.

Wrap Up

If you can’t stand mummy bags and need a spacious option, this is a great bag to get. It won’t do you any favors in regards to weight, and there’s cold spots in the bottom of the bag to consider, but it’s still very comfortable and easy to get a good night’s sleep in.

The Nemo Nocturne 15 Degree Sleeping Bag is one of Gear Head Junkies best three season sleeping bags that we have tested in the field. Its ultra comfortable, light weight, and super compactable making it one of our top go-to bags for backpacking.


I wish this bag kept me warmer in colder weather. In 15-20 degree nights, I was sleep cold, wishing I had an I.V. of hot chocolate pumped into me.
I wish it came with a compression sack.


Overall, this is an amazing sleeping bag. I have slept in mummy bags to often over the years and after using this bag, I wont be going back. I am a side sleeper and this bag was designed with me in mind.
