With its mummy shape and innovative design that eliminates traditional stitching, the flame orange Lamina Z Spark 34°F Sleeping Bag (Regular) from Mountain Hardwear offers warmth in cool temperatures while remaining lightweight and compact. Comfort-rated for 42°F, it carries an extreme temperature rating of 34°F.
The Lamina Z's Thermal Q synthetic insulation is welded to the shell and liner, rather than simply sandwiched between two sewn-together layers of fabric. This method eliminates the cold spots that occur at stitching lines, where insulation is pinched and loses its loft. The insulation is "mapped" for extra coverage where it is needed most, your core and your feet.
The bag seals out drafts with a full-length zipper tube, a draft collar and a face gasket within the tailored hood. Your feet will be both warm and comfortable thanks to the comfort footbox, which has room for them in their natural position.
The shell of the Lamina Z is water resistant, so you won't get wetted through from tent condensation or dew if you're under the stars. The soft polyester lining is designed to wick moisture away from you during the night. Packed in its stuff sack, the Lamina Z Spark measures 6 x 12" and weighs 2 lb.
