The best bag I've ever owned!

  • Gender: Female
  • Familiarity: I've put it through the wringer

This bag is amazing. I have used it in all kinds of weather, cold and rain and its never let me down. I sleep under a tarp and even if it gets a little wet, the down stays dry. Its super lightweight, compact and seems to hold well. I'm probably on year 4-5 of using it and I would buy it again without hesitation.

Curious if this bags zipper would be compatible with an REI subkilo 20 bag. Does anyone know what the YKK number of this zipper is?

I am 1m 68cm tall (roughly 5ft 6in) so I'm wondering if I'd be confortable in the regular women's size or should I get the long women version. I have 2 regular unisex sized sleeping bags and I find the extra room in the feet area too much.

Responded on

The regular will b too small (sort).

Hey Katish, it all depends on how you sleep. I've got a sleeping bag my exact height and it's perfect for me. However, I tend to sleep on my side with my body partly curled up, so I'm usually not stretched out to my full height. If you're a back or stomach sleeper, the 5'5" length may be a little short since you're already 5'6". You don't want your feet pushing too much against the bottom of the bag while you're sleeping as that will make them cold.

The neck baffle!

Recently I realized that one of the great things about this bag is the down-filled neck baffle (or face gasket according to them?) it has. So when you are sleeping, the cold air that could possibly get into the bag from the open hood area is blocked because the neck flap/baffle. It is soft and not at all constricting. I noticed this recently more from using other sleeping bags that didn't have this feature and wishing that they did.

Good Spring/Fall Bag

This is the first spring/fall bag I've had and I'm really glad I picked it up. In the past I've just had summer and winter bags which means the transition seasons usually suffered by being too warm in a 0 degree bag, or on the cold side with a 32 degree. The Phantom 15 is a great go between. It's still really light, but plenty warm.

Seen lot's of zipper issues, but haven't noticed any yet.

I've heard that the zipper catches a lot on the MH Phantom 15 and am trying to decide between this bag, and the WM Versalight. Does anyone have experience with the zipper issue?

Responded on

Go for the WM bag - its a superior bag over all - and no zipper issues.

Responded on

I second knanier. Definitely go with the WM. Great quality, well worth the investment.

Responded on

Yes the zipper catches on the MH one.

I'm hoping to match this to my MH Galaxy...

Posted on

I'm hoping to match this to my MH Galaxy 20. What number YKK zipper is it?
Also, does anyone have any feedback on the durability of the fabric?
Finally, the MH website states this is a 2 lb bag, but it says it's only 1lb 4 oz (for the regular) here. Is the 1lb 4oz just the fill weight? Thanks!

Responded on

nic. Unfortunately, we use a lighter gauge YKK zipper in the Phantom 15 than is used in your Galaxy. We wanted the Phantom Bags to be as light as possible and this is why we went with a smaller/lighter zipper. Afterall, the zipper is the heaviest thing in or on the bag!

I have both a Phantom 0 and a Phantom 15 that I have traveled extensively with around the planet. Although the fabric is extremely light and therefore not that durable I have never had an issue with durability under normal use. What is normal use? Well, inside a tent or bivy sac and not packed next to the crampons in your duffel! Pretty basic.

As for the weight posted on the site? Good catch. It is wrong. The Phantom 15 according to my Spring 2011 workbook should be 2Ibs.1oz. for a regular size and 2Ibs.4oz. for a long. I will make sure the weight is updated on the site here.

Thanks! I hope this info helps.

How many ounces of down fill does this bag...

How many ounces of down fill does this bag have? Is it overfilled around the waist and in the footbox like other women's bags? Thanks!

Responded on

Mads. The Women's Phantom 15 Bag has 20oz. of 800-fill down for the Regular length Bag and 22oz. for the Long bag which equates to about 6" of loft! Also the women's bags are a little bit shorter than the men's bags but maintain the same amount of down. So, they are warmer for their given lengths and widths than the men's bags. I hope this info helps!

Responded on

Thanks so much!! You're more helpful than MH :) I'm trying to decide between this bag and the Marmot Helium (women's version). You seem pretty well informed so I was wondering if you have an opinion between these bags? I've been using the Lamina 20° but I'm looking for a way to shave off some weight while adding a little bit of warmth. Overall I'm happy with the Lamina although I hate that the zipper gets stuck all the time.

One additional question: is the down evenly distributed on both sides of the bag? I'm a side sleeper so that's helpful for when I roll around at night. Right now I'm using a men's bag with plenty of extra wiggle room so I can sleep sideways without having to tilt the bag on its side. I'm not sure if I'll be able to do this with a closer fitting women's bag.

Thanks in advance for any advice!

Responded on

Mads. I've been answering a lot of questions on this site and unfortunately just saw your reply and subsequent questions! Sorry about that. So, not sure if you have purchased a bag yet but obviously since I am one of many Mountain Hardwear Reps I think you know what I will say! Go with the Phantom!

The down is as evenly distributed in the bag as we can make it. Hard to keep it all in one place but I have never had a problem with down migration in my Phantom. One reason for this is that Mountain Hardwear uses Side Block Baffles in our bag designs. This keeps the down either on the top of the bag or the bottom as opposed to some manufactures that think it is better to be able to move the down around the bag. The idea here is that you WANT the option to move down around the bag to make it warmer or cooler depending on the environment you are in. We figure that during the night folks naturally roll around and we want the down to be where it is supposed to be at all time. Sleeping sideways should not be a problem in this bag. Again I hope this info helps and thanks for the comments!

The picture shows that this bag does not have a full-length zipper, but I think the bag does. Does this bag have a full-zip?

Best Answer Responded on

Actually, it DOES have a full length zipper and that is what is shown in the photo. The Phantom bags used to have a 3/4 length zip but that changed to full length zipper in spring of 2010. Hope this info helps!

Is the MH Phantom 15-Women's compatible with the MH Phantom 30-Men's?

Is the MH Phantom 15-Men's compatible with the MH Phantom 30-Men's?

When I say compatible, I mean can they zip together?

Responded on

Ruze. If they are the S'10 bags you should not have a problem zipping them together. The reason they need to be the S'10 bags is because in S'10 they came with a FULL zip. In '09 they had a 3/4 zip. Also make sure you get a Right Hand Zip and a Left Hand Zip so that they zip together perfectly. I hope this info helps!
