Set Phasers To Sleep.
Worrying about being attacked by icy gremlins is a really good way to lose a good night’s sleep, but the Marmot Phase 30 Degree Down Sleeping Bag will keep those chilly little demons at bay. The Phase 30 will keep you comfortable during spring, summer, and fall adventures whether you’re sleeping under the stars or in the back of your car, and the water-resistant down and fabric won’t get soggy with dew if you opt to fall asleep looking at Orion.
There’s more to the Phase than warmth, though. It’s lighter than a feather (well, a whole mess of feathers), and has slightly stretchy baffles so you can comfortably work on your sleep-dancing. Marmot even hooked up an internal pocket, so you can have your light handy when you wake up in the wee hours needing to explore the woods.

- Q & A
Nice light bag
- Familiarity: I've used it several times
I read a review on Outdoor Gear Lab which calls this a 40 degree bag, mislabeled as a 30 degree bag. I own a Western Mountaineering 30 degree bag, so I figured I had some basis for comparison. The WM bag is about 15 years old and contains similar quality down, but is not the water-resistant kind. I do a certain amount of backpacking in areas that get substantial condensation.
Anyway, I would probably call the Phase 30 more like a mid 30's bag, at least for me. This is a very light sleeping bag, and I used it with a silk liner, midweight base layer and a marmot driclime windshirt; pretty typical in my case. At temps in the high 30's I was not cold, but feeling a bit of a chill in the legs and feet. The next two nights were warmer and I did not even zip it up completely. Springtime weather, you know, can't make up its mind.
I got mine at the recent sale price. It's an ultralight bag; expect the zipper to be dainty and the fabric fragile. I'm used to it. If you need a bombproof bag you are going to have to carry the extra weight. Enjoy the journey.
Super duper lightweight
Unbelievably light and compressible. Can't wait to test this out once the mercury goes above zero. The zipper is definitely easily snagged, but the other benefits of weight, size, and quality can't be stressed enough.
"The Marmot Phase 30 . . . compared to the best-of-the-best bags . . . is still lighter weight, roomier, and more compressible . . . from every standpoint, this is one of the very best sleeping bags currently available". Having now purchased one from Backcountry, I agree with this quote from Outdoor Gear Lab.
Zipper: The tiny zipper snags easily. You have to be careful, but it doesn't look like it will break. Personally, I'd rather have a tiny 3/4 length zipper on an UL bag then a larger 1/3 length zipper.
Comfort Range: For me this was critical. I have now spent a night in this bag at an inside tent temperature of 32F (0C) with NO ISSUES. (Male, no socks, only shorts + a quick-dry shirt, mat rated at R8).
