Cheap hood and draft collar draw cords

  • Familiarity: I returned this product before using it

Very cheap lightweight hood and draft collar draw cords, one of them was not even anchored when received and pulled right out of it's sleeve. I returned immediately.

Excellent bag for the money

  • Familiarity: I've used it several times

The Lamina 0 degree bag is a great sleeping bag. I use it on the AT and it's so warm that most nights I sleep with it half unzipped. Although the bag doesn't come with its own compression stuff sack, I purchased one for it and it packs down just perfect to fit into the bottom of my Kelty Redcloud 90 with extra space to fit my sleeping pad as well. I like the dual zipper feature which allows you to zip open the bag from the feet for people who like to air out there feet or help regular the internal air flow.

Unanswered Question

I see that John Webb speculated that the EN ratings would be EN comfort 19 and EN limit of 4. Since the UltraLamina 15 bag has EN ratings of Comfort 17; and limit 5, I wonder how he arrived at this. That would mean a Mountain Hardwear 15 degree bag is warmer than the 0 degree bag..

Unanswered Question

I am trying to select a bag for Pico de Orizaba this December and not completely break the bank. Would this bag work well? I sleep pretty hot. I was also looking at Marmot Never Summer and EB Karakorum 0F Down (expensive) and synthetic. Thanks!

I am 5'4". Will the "short" size be sufficient or should I consider the "regular"?

Hey quinnbear,

At your height I would suggest getting the short variant.

I know this says it's a 0-degree bag, but what is the comfort rating on it?

Best Answer Responded on

Hi Molly S., Sleeping Bags 0 degrees and below do not require an EN rating to be sold in Europe and so they are not given the standard "comfort" "comfort limit" or "extreme" ratings... they are simply considered to be warm! With that said, base on EN ratings that we give to other bags in our line I would guess the Comfort Rating would = 19 F, Comfort Limit = 4 F, and Extreme = -33... not sure why they even give bags -33 extreme rating as I don't think anyone is going to take a 0 degree bag out when it is -33... anyway. I hope this info helps.

Super packable winter bag

  • Familiarity: I've put it through the wringer

I got this bag 2 years ago and have been very impressed. The best thing about it is it compresses to an amazingly small size. I use a Sea to Summit UL compression sack which shrinks this bag to be almost as small as my summer down bag! Since it packs so small I took it on a 4-day Inka Trail trek (on top of a 3 week backpacking trip) in May and was super warm (the Inka trail can get cold at night). I also use this as an emergency sleeping bag in the summer in Arctic Canada. This bag is also breathable enough that I use it as an extra layer at home under my quilt in the winter! I am 5'4" and the small size fits me perfectly. My feet don't feel cramped but there is not a lot of extra room (with other bags that don't fit too well I have to stuff clothes in the bottom to take up the extra air space). The bag also has shoulder yolks and beefy draft tubes down the zipper for extra protection against the cold. I haven't tested it in Canadian winters but it is very toasty for spring and fall camping in Ontario and compresses small enough that you won't have to debate over taking a lighter bag and risking being cold in the shoulder seasons.

Weight off, great construction...

First impressions FYI- I purchased new models of both Lamina 0 Long and Lamina -15 long, the -15 was right on with its weight... The MH specs claim the long Lamina 0 to be 3lbs 14 oz, however, with a compression stuff sack that weighs 4oz I'm getting 4lbs 7oz on a very accurate (and calibrated) digital shipping scale... So 4.7-4 = 4lbs 3oz, roughly 4 to 5 oz on the HEAVY side... So maybe mines a bit more stuffed... We did just finish Thanksgiving ;), FYI, weighed at 2600 ft elevation...

Will return to review its quality in reality after this weekend- going up to high country for one night- supposed to get 2-3feet of snow over Friday night, and temps -10 to -20 F... Will be inside an old Tiros 1 SD... LEGENDARY great tent though... Also trying out new Asolo Titans

Happy Trails

How many liters does this bag pack down to with a compression sack??

Responded on

Well.. the "base" stuff sack size is almost 17 liters, but it really depends on how much you think you can compress it after that.... maybe by half at the most?

warm bag!

  • Familiarity: I've used it several times

This sleeping bag is great! I needed a bag for winter camping and this one is perfect. It is VERY warm which is good because I sleep colder at night and it is great for wicking moisture. The fabric is very durable and the bag itself is comfortable

  • Familiarity: I've used it several times

I love this bag! I get cold very easily and I often sweat when I sleep, but I haven't had any of those problems in this thing. The polyester lining is definitely doing its job and wicking away moisture.

I recently used this bag "under the stars" and when I woke up, the outside was completely covered in dew, but I was warm, dry, and cozy on the inside. The face gasket is perfect for situations like that, when all you need is a way to breath, but want to trap as much heat as possible.

Does this thing have rip-and-stick (aka velcro) anywhere near the face/head area?

Best Answer Responded on

Hey bud- the lamina 0, see my above review- has a Velcro flap to secure the main zipper at its top limit, a dual adjustable hood draw cord, the inner "neck ruffle", for lack of better words, has its own tension cord as well, but no Velcro to lock it around your neck... The -15 Lamina version DOES have Velcro on the inner neck guard though... Funny, I noticed that as well and was bummed for a few minutes...

Whats the difference between the thermic micro fill and the thermal Q fill?

Best Answer Responded on

Thermal Q is allegedly an improvement of thermic micro fill, which is Mountain Hardwear's version of Primaloft. They still seem very similar to me, but the new version (Q) is supposed to be 20% warmer. Warmer than what exactly is what I'm not sure about, and backcountry seems to be using the terms interchangeably on MHW products. Here is more of an explanation:
