“This dry bag replaces the one that came with my S2S Spark III sleeping bag. The original sleeping bag sack was a 6L compression stuff sack, only sorta water resistant, this new 13L should be waterproof and is so much easier to put the sleeping bag into. It then squishes down to not much more space than the 6L. The extra 50g over the original is very reasonable for the convenience it gives.”
