With its mummy shape and innovative construction, the HyperLamina Flame Long Sleeping Bag from Mountain Hardwear offers warmth in cool temperatures while remaining lightweight and compact.
The HyperLamina's Thermal Q 60 gram 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's half zipper reduces the size of another potential source of heat loss.
