Out of all the three light-weight bags I own, Marmot Sawtooth (15F), MTH Lamina 45, and MTH Phantom 32, the Phantom is by far my favorite. I have tested this bag in extended days of downpour rain as well as dryer days in sub-freezing weather. Its extremely light weight and very compact (slightly taller and slightly fatter than a Nalgene). Regarding its quality, this bag is top notch. I've owned this bag for over a year, and have stuffed and unstuffed it many times. In that time period, I have only seen maybe two feathers leak through the down proof material. In contrast, my the fabric of my Sawtooth constantly leaks feathers. The fabric has a nice face and a tight weave, and as a result, it is slightly water-resistant. Furthermore, the zipper glides effortlessly without snagging.

As far as comfort is concerned, the bag breaths well, the hood is very comfortable, and unlike other superlight bags in this class, the Phantom has a 3/4 lenght zipper. In contrast to some other bags I have such as the Sawtooth, the Phantom stays dry. The outside is never soaked with condensation, and any that builds up, I have been able to wipe off without it being soaked up. Also, the inside stays dryer, even if I overheat and doesn't feel damp in the morning. The coldest I've tested it has been 28F. I was wearing Patagonia Cap 3 top/bottom, smart wool socks, hat, etc, on Thermarests, no tent and breezy. I wasn't cold the entire night (though I wasn't really warm either). Considering that I was below rating and without a tent in the wind, the bag surpassed my expectations. In weather warmer than about 50F, the bag does get steamy, so consider the Phantom 45 for warm summer trips.

I'm 5'4", and for me the bag is extremely roomy. If you are larger, and like room, you shouldn't have any problems. As of now, I am so impressed with this bag, that I am planning on buying the Phantom 45 as well. If you are looking for a great, light-weight, high-quality bag that doesn't lack comfort, get the Phantom 32, you won't regret it.

My Phantom bag is very warm, light, and compresses impressively. Maybe too warm for summer in Colorado? My only criticism is the lack of a full length zipper. The bag is very warm but on warmer nights my legs and feet start to feel claustrophobic. I really like the feeling of the fabric, construction is first rate, and I am confident that I'd be plenty warm at 32 degrees. I just need a full length zipper, so I kind of wish now that I would have bought a different bag. It is a personal preference and sleeping style issue which I didn't give much thought to. Backcountry.com though was a good place to purchase the bag, I found the reviews on products helpful - but somehow missed on considering the lack of a full length zipper - I got too caught up on the weight issue I guess.

I'm KNOW I'm going to get flamed by a few forum addicts and MH die-hard fans (I'm a MH fan too!!!!), BUT I've got to question whether or not this is really a 32f bag. I recently did two nights out in this bag (before returning it). The first night's low was right at 32f and I wasn't any too warm (and I like to sleep COLD) with a wool beanie, wool socks, and a thermo base on! The second night the temp. dropped to 20f (at it's lowest, and YES, I know I was pushing the bag here!). Geeze, I had everything I brought on..... and was still COLD. The other problem I had with the bag is it's shell material. I noticed that the 15D shell allowed a few feathers through on every use. On the postive side, the bag is incredibly light and well put together. The long, as stated, was exactly 1 lb - 7oz within it's compression sack. But, I decided in the end that a little more weight on my back was better than going through another night like these (above)! Has MH become too obsessed with being the lightest on the market?

This bag goes with me on 75% of my trips. It packs ultra small and compact, you dont even notice it. Temperature rating is pretty accurate. I sleep pretty warm anyways, and Ive had it out below 32 degrees and it worked fine for me. Im 5'8" but I got the long version for clothes and other items, and to just have some more wiggle room. Very nice bag for spring, summer and into fall.
