Sea to Summit Spark Ultralight 18 Sleeping Bag Review

All Spark sleeping bags are characterised by their ultra-light weight, minimal packing size and excellent thermal performance. The Spark SpII features vertical breast chambers that are stitched throughout for extra down and reduced cold bridging. Other continuous horizontal chambers in the foot area minimize the weight. A half-sided zipper with two sliders makes a comfortable entrance possible and serves for additional ventilation.
