Product details
All Spark sleeping bags feature ultra-lightweight, minimal pack size, and excellent thermal performance. In the Spark SpII, vertical chest chambers sewn throughout contain an extra amount of down to reduce cold spots. Additional sewn-through horizontal chambers in the foot area minimize weight. A half-zip with two sliders allows easy entry and provides additional ventilation. The optimized sizes of the Spark sleeping bags offer more space at the shoulders and hips. The integrated zipper channel prevents heat loss, and for added protection, the SpII comes with a thermal collar.
Ultra-Dry Down is a PFC-free, water-repellent down treatment used in all Sea to Summit sleeping bags. UltraDry Down retains over 60% more fill power, absorbs 30% less moisture, and dries out 60% faster than untreated down, meaning the down insulates better even when damp. The treatment also inhibits bacterial growth and extends the life of your sleeping bag. The UltraDry Down treatment is an environmentally friendly application.
