MOUNTAIN HARDWEAR PACK FIT GUIDE and INFO

• Determine the correct pack size by measuring from the top of your hip shelf to the C7 vertebrae, which is the protruding bump at the base of the neck.

• If you think you are between pack sizes, consider how and when you will be using the pack. For example, if you will be using the pack primarily in the winter, when more and bulkier clothing is required, you may opt to size up.

• You can find Torso Range and other size information in the description FEATURES or SPECIFICATIONS for each Mountain Hardwear pack. You can also refer to the size guide below to compare the current season packs by category.

Rated 5 out of 5 by from Warmer than you think This bag has the best warmth to size & weight of any bag I have tried. The zipper can make it kind of a pain to regulate temperature on warm nights or to get out of in a one person tent. But it's worth it for how much warmer your feet stay. For me, this is a good compromise on quilt v bag. on warmer nights I will flip the bag upside-down & leave it unzipped. Comfort of a blanket while staying put & keeping my feet warm.

Rated 4 out of 5 by from Great if you're not clostrophobic I have learned a few things about myself after trying many sleeping bags and sleeping pads. I can't use either one of them. What caught my attention about this bag was when I watched a video about it, and saw that it packed up ultra small. I was sold. What I realized when I got it, was that I am clostrophobic and can't be in this bag with this zipper where it's at. Mountain Hardwear makes a newer Spark bag, not this exact same one, but it is a 34 degree bag, orange, and has a long side zipper. In conclusion, I dislike the colors. Can't these bag makers pump out a black bag? For me, the selling point is the packability and warmth. However, I can't be in the modern day mummy bag, so I am returning all my bags, putting on my warm and waterproof clothing, returning my sleep pad, and sleeping under a tarp. To each their own. If you aren't bothered by mummy bags, bright colors, and want ultra packable, get a Spark bag. It's not the bag, it's me.

Rated 5 out of 5 by from Mountain Hardware HyperLamina Spark sleeping bag I love this bag. It's crazy light and packs down to nothing. It kept me warm toasty on an overnighter at Zion National forest where it was in the low 40's. Highly recommended this bag!

About how far does the zip go down in the long length in comparison to your body? Is it possible to get some air to your feet?

Asked by: Aaron l
Hey there, The zipper on the Long Length of this would go down to about your waist, depending on your body type and height.The zipper ends halfway down the bag to help lock in warmth and prevent cold spots along the lower half of the bag, so sadly it can be difficult to get air moving down there. I would suggest leaving the bag unzipped for a few minutes when you need to cool down to allow the outside air to travel down through the bag.
