Excellent bag!

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

Warm bag, and super comfortable. Decent amount of room in a long (I'm 6'6"), and there is enough room for me to be comfortable. The zipper setup is nice, with the dual zippers to the hip, however they can snag, so you do need to be careful zipping up the bag. Hood adjustments work decently, and allows you to cinch up the hood well. The welding design of the bag does help to provide an even amount of insulation, never had a cold spot.

Great bag - bad zipper

I had a big problem with the zipper being caught in the fabric the first time I tried to zip it up. It would not move up or down and I ended up sleeping in 19 degree tempatures with my bag open. The good news is that the bag is very warm for the weight. I would highly recommend this bag based on compression, weight, warmth but the zipper is cheap. I'd give it 5 stars if it had a better zipper

How far down does the zipper go on this bag? My current bag has a two way zipper, so you can unzip the feet a bit if you're feeling toasty. does this bag have this features?

Responded on

The zipper goes to about hip height and I dont think there are foot zips

Comfortable at temps

This bag took me down to 20 easily in the back of a pick up bed without cover. The head draw strings were a bit unusual. Only major problem is the zipper set up on this. The double zippers zips only halfway and that was not working for me. I guess if you spend time sitting up in the bag this may be for you. When I am up I am out. The half zip made midnight necessity trips near impossible. This one is going back. Also the stuff sack failed. Be careful as it is sil-nylon and is not really rugged. If you need a warm inexpensive bag to sit up in this is it.

I just wanted to ask how the Ultralamina 15 compares to the (2011) North Face Cat's Meow, from someone who owns or has used both. How warm are they in comparison? Is there any difference in weather resistance (rain, wind, etc.), and just how comfortable are they in general? Also, is there a new version of the Ultralamina 15 coming soon? I noticed that it’s been on sale at a lot of places and, from what I've seen; this means there could be a new model upgrade. I would love to save money on this bag but, if an improved version is coming, I would gladly pay a few dollars more. Or, is this simply a lot of spring sales happening at the same time, to make room for summer bags? If these sales expire before I buy a sleeping bag, is the Ultralamina 15 worth the extra price over the Cat's Meow?
Sorry for all the question, but I would really like some more information on these two bags.

Best Answer Responded on

A Weber. I'll see if I can answer your questions. To start, both bags are great bags and you can't go wrong with either but comparing the two is like comparing an apple to an orange. First, the Cat's Meow is a 20 degree bag where the Ultralamina 15 is a 15 degree bag as you probably guessed so there will be a little more insulation in the Ultralamina. Secondly, the Ultralamina is made in a completely different way than the Cat's Meow. The Cat's Meow is made in what would be considered a more traditional build where the insulation is sewn in a "shingled" fashion to overlap for warmth and then kept from moving around in the bag by baffles. Much like the construction of a down jacket. The Ultralamina is made very differently. First, we lay one complete 'bat' of insulation (one piece)in to the bag, then sew around the edge of the bag to anchor it in place from the side. After that, we anchor the insulation again by welding it to the shell of the bag there by eliminating the need for baffles. The Lamina Bags and Ultralamina Bags are made in this way and it is a very cool way of making a sleeping bag which lowers prices, eliminates cold spots, and increases loft. Now for the obvious comparisons: In Mountain Hardwear Synthetic Bags we use something called Thermic Micro which is a short staple insulation very similar to primaloft in design and construction. It has a higher amount of silicon in it than other insulations on the market and less resin which allows for more water resistance and better stuff-ability overall. We are able to use this highly stuff-able insulation due to the special construction of the bag. The Cat's Meow uses Climasheild which is TNF's proprietary synthetic insulation which is a continuous filament insulation. The Cat's Meow weighs 2Ibs.12Oz. for a long and the Ultralamina weighs 3Ibs.2oz. for a long (6oz. difference for 5 degrees = not bad!) We use a 20 Denier RipStop nylon for the shell fabric and a 20 D Taffeta for the lining. Very lightweight, nice feeling, and comfortable fabric. The Cat's Meow uses Ripstop and Taffeta as well... just not sure what denier as it is not listed. The smaller the number of denier the lighter the fabric.

As for the pricing of the bag? Well, I would say that there are what amounts to pricing wars going on over the internet. This is the current version and an updated or newer version would not be available until spring of 2012.

I hope this info helps!

there isn't a better 15F synthetic bag for the price

there simply isn't a better 15F synthetic bag than this. Used it with a liner for a year in the backcountry of Alaska. loved it - it kept me warm, packed down to nothing, all at an affordable price.

I have already decided on this bag, just wondering what size i should get. i am 511 185 lbs. i dont want it to be to tight but i dont want to be cold either, any help would be awesome! thx

Responded on

If you don't want your sleeping bag to be too confining & you are on the line between medium & long, go for the long & be more comfortable.

Responded on

I buy longs in cold bags (15deg or less) so I have room to put my boots in the bottom. Few things suck more in the morning than cold boots. Ideally, I hike to camp, switch to either a down bootie, sandal or some other comfortable footwear, let the boots dry, clean them off before I go to sleep, and tuck them in the bottom of the bag. Sometimes the heat helps dry them out, other times not, but they're always warmer than leaving them in the vestibule all night.

Synthetic

Cant adequately rate yet. It is much smaller, lighter than the 0 degree bag from Northface. I am not sure what I am loosing in thermal tolerances. Seems well put together. The stuff sack is a bit strange but seems to work ok. There is a small pocket for ear plugs and other sleep related things. I have not pulled it on so I cant comment yet about size, fit or function.

I having a hard time choosing between this bag and the Lamina 20.
I know this is a great bag, but does it worth the extra $$$ compared to the Lamina 20?
The temp diff is fair, also the weight and compression. What makes it cost 30-40$ more? Does it worth it?

Best Answer Responded on

Lior. The reason that it is slightly more expensive is because of the lighter/softer feeling fabrics used to make this particular bag and the fact that we use slightly more Thermic Micro insulation. Otherwise, the choice is between the differing zipper configurations. With that said, both bags will treat you well! I hope this helps!

I've got the MH ultralamina 32 degree and it has been an absolute gem. I used it for multiple months in AK and New Zealand...both fairly wet and cold environments. The 32 degree is quite nice but I favour something slightly warmer...Does the 15 degree provide warmth late season backpacking in snowy or wet/cold environments demands?

Responded on

actually, I don't have an answer for you but I am going to do some of the tracks in F-Land, NZ and am wondering ifthe 32 temp was warm enough for that environment? (or warm enough for summer/march camping)

MtBiking Touring Essential...

The compressed size, weight, warmth, and water resistance of this bag have made it ideal for me. I'm 6'3", 220lbs and the long version of this bag fits me perfectly. Dual zippers are really awesome in the morning when you can't seem to roll out of your bag...unzip, stick your arms out, get some coffee going, life is good!

I own the Ultralamina 32 degree bag and have absolutely loved it. It's been great from Alaska to New Zealand, and its packability and water-resistance is unbeatable.

I do, however, want to pick up something a tad warmer.

It sleeps very warm, I've used this bag in conditions which would definitely test this rating, slept like a baby, except wasn't wet like one.

Warm and Light

This bag is light and packs down small. When it says 15F it means it. You will sweat your A off in this bag if its not winter time. Great bag overall.

As advertised, Warm, Small and Light... but too tight.

I'm not a sleeping bag expert, before this bag I have never owned an expensive bag. The bag packs very small and light about 8"x10" when fully compressed and the listed weight is right on. The lining is silky to the touch. My only problem is that the bag is a bit narrow for me, but I am a overweight (5'9" / 240lbs) and I toss and turn in my sleep. If it has 3 more inches in circumference in the shoulders it would be perfect.

The bag is a bit warm if the outside temperature is higher than 40 degrees, with no way to vent the foot there is not much you can do about it other than taking your arms out. The warmth is just about right for the 10-40 degree range with a lightweight base layer. The cost of the decreased weight is versatility.

anybody have an issue with this bag being too warm??? i'm concerned that you can't unzip the bag as far down the side as most others. does having the double zips make up for that?

Responded on

If it is above 40F outside it will be too warm in this bag. Because of the tightly weaved fabric and the lack of foot vents you have to be careful to control your temp so you don't sweat.

Write your question here...Can two of these Ultralamina sleeping bags zip together to make a double?

Best Answer Responded on

Actually Jeff.. the Ultralamina bags CANNOT zip together due to the positioning of the zippers. The Lamina Bags CAN zip together and that may be where the confusion is coming from. So, to re-cap: Ultralaminas= NO Laminas= YES when it comes to zipping together. Hope this helps!

Responded on

Thanks so much Jon Webb for the info. I am looking for a pair of 0 degree bags that are very light and can zip together. Lighter than the northface snowshoe long mens and womens. Do you have any suggestions?

Review Title

bag works great for 3 season use, even without a tent. I have yet to use it in the snow, but from use so far, a liner should be enough to keep me warm.

Zippers are cool, they work and a draft tube keeps out any air.

Don't try to over-compress the stuff sack, the clips aren't that strong and will come off.

4 5

It works

Don't know what to say, it's a sleeping bag and I sleep in it. The dual zips are a cool feature, but one that would go down say 2/3 would be handy for getting out easier in some situations. I'm kinda disappointed that it's lost its loft somewhat since new but it still gets the job done for a 3-season bag.
