The Mountain Hardwear HyperLamina Spark sleeping bag and its 32 degree temperature rating deliver 3-season comfort and quality performance. The performance mummy cut is snug, reducing girth, weight, and bulk and maximizes thermal efficiency.
The HyperLamina Spark is insulated with compressible, durable Thermal.Q synthetic fill. Unlike most natural down fill, Thermal.Q is water-resistant and continues to provide warmth even when wet. This is particularly important if you'll be backpacking or camping in wet weather or humid climates. Thermally mapped insulation and half-length center zipper maximizes efficiency.
The HyperLamina utilizes welded construction which eliminated cold spots and enhances loft, comfort and warmth. The ergonomic draft collar blocks the escape of heated air from inside the bag. Mountain Hardwear's patented Comfort Footbox creates an ergonomic, insulated space for your feet.
The Mountain Hardwear HyperLamina Spark sleeping bag is available in Regular (fits up to 6' 5") and Long (fits to 7' 0") lengths.
