    Details

    Make cold spots a thing of the past.

    Mountain Hardwear designed the Lamina Z Spark 34-Degree Synthetic Bag to virtually eliminate cold spots, so you don't wake up cold in the middle of the night. The bag's welded Lamina construction prevents the Thermal.Q insulation from migrating and leaving you with cold spots, and the strategic insulation mapping concentrates warmth around your core and feet, helping your most important and vulnerable spots stay warm and comfy.

    Condensation can also leave you chilly, so Mountain Hardwear finished the Spark's Lamina Revamp nylon shell off with a DWR treatment to repel water. The face gasket and tailored hood stop heat from escaping from out the top of the bag, and the comfort mummy shape and footbox provide a slightly roomier fit for better insulation and more room to move.

    Temp rating was right on.

    • Familiarity: I've used it once or twice and have initial impressions

    I wanted a bag that would be warm enough as I sleep cold, but not too hot as I was camping in UT July and it can stay fairly warm at night.
    This bag held up to the 34 degree rating perfectly, I did have to sleep in my down jacket and socks to be totally comfortable, but that is pretty normal again, as I sleep cold personally.
    My favorite things about this bag is that for the temperature rating, it packed down super small to fit into a 40L bag without taking too much space up, about 6" long with a circumference of about 11" even though the specs say 12". It was a light as it says in the specs too, which was awesome and left plenty of room in my pack for food, clothing, and of course some beers!

    I would definitely recommend this sleeping bag for spring and summer camping.

    nice small packing synthetic bag

    I took this bag backpacking in Glacier over the summer. I am 6 ft and this was the regular size. Wish i had the long. Would have been more comfortable. Kept me warm in temps around 40 but 30 would have been too cold for me. I recommend this to people looking for a more entry level. Great value!

    nice small packing synthetic bag

    great bag, beware of published specs

    • Familiarity: I've put it through the wringer

    I purchased the Lamina Z Spark to have around in addition to my MH Ratio 32 down bag, simply as an alternative for predictably soggy trips. So far it has worked great. I have had it down into the mid 40s and high 30s and have stayed nice and cozy throughout the night sleeping in just base layers. It is very roomy, .



    The Lamina Z Spark is impressively warm for how lightweight it is, and my Large size bag packs down to about 7" x 13" in the compression sack. Minus the stuff sack, my bag is 2-3 ounces heavier than advertised, so if you're picky about that, be forewarned.

    great bag, beware of published specs
