Mountain Hardwear Phantom 0F/-18C

Great option, but maybe not the best option.

Overall a great bag. I tested at a local camping store but purchased from Sunny Sports as they had the bag for $120 cheaper. I went with this for colder Colorado hikes and it holds up well down to near zero temperatures.

I was between this bag and comparable options from Feathered Friends and Western Mountaineering. In the end it came down to this bag and the Western Mountaineering Antelope. This bag was heavier than the Antelope and did not have continuous baffling, which can be a plus or sometimes a curse (depending on your storage habits).

I liked the asymmetrical neck baffle and I trust the Mountain Hardwear name so I went with the Phantom. It is also a little more snug fit and doesn't pack down as small as the Antelope, but I found it to be more comfortable during limited in-store testing.

You have several choices in this temp and price range but it really only comes down to two: the Mountain Hardwear (MH) Phantom and the comparable Western Mountaineering (WM) Antelope. The comps go as follows:

• Comfort: MH
• Fit: Closest but WM
• Neck Baffle: MH
• Packability: WM
• Warmth: MH (but this is only through Trailspace and similar review sites, as both were not tested outside the store)
• Price: Tie
• Weight: WM

See which of the above you value most and hopefully this will help you you make an informed decision. 

Good cold weather bag.

I have the long version of this bag. It's very warm, the coldest I've had it was at 2°F, -17°C on a Therm-a-Rest Xtherm. I was very warm.

The interior pockets are a very nice addition, but as with all the Phantom bags, you'll be wrestling with a snagged zipper if you don't take the time to be careful with the zip.

This is a cold weather bag, if you try to sleep in this above freezing point, you're going to be too warm.

I bought this sleeping bag a month ago and did Everest trek in it. Before using it i thought it was quite expensive but after using, my impression was totally changed. Now I have a confidence to sleep easily and warmly even in very low temperatures.

The only drawback I feel is a little greater volume and no inner zip handle. Overall very good.

Great weight-to-warmth ratio. Used in temps below 0. Have used for 3 years and no complaints

Used this bag in below 0 temps in the Sierras and Alaska. Lightweight. Warm. Compacts nicely with a 16 liter compression sack. Use a liner and very comfortable.
