Mountain Hardwear Hyperlamina Spark sleeping Bag - REVIEW
Mountain Hardwear's new HyperLamina Spark is designed to be the lightest, most compressible synthetic bag on the market. Does the Spark live up to this high praise? Well from this reviewer’s standpoint it does come in with some great features that make it hard to beat for those fast and light summer trips. The thermally mapped insulation made with proprietary Lamina welded construction, help in reducing weight and bulk. This also helps with a higher warmth rating for a reduced weight penalty. Lamina welding is essential a technique where the insulation is welded to the shell and lining to eliminate stitching. If you look closely at the HyperLamina you’ll notice very few sticked seams and none across the top of the bag where you traditionally see the stitched baffles. This in addition to different insulation weights in different locations eliminates cold spots and places more insulation where it's needed. Most notably, there is more Thermal.Q synthetic insulation in the core and foot area while the underside is noticeably thinner. This helps keep you warm but also reduce weight which is important.
