Is the compression sack that comes with my sleeping bag waterproof?

Sea to Summit sleeping bags come with either an Ultra-Sil Compression Sack or Nylon Compression Sack. While the fabric may provide some water resistance, the seams are not sealed and the pull-cord closure will allow water inside. 

If you would like to upgrade to a waterproof bag for your sleeping bag, you may care to take a look at our eVent Compression Dry Sack (external use - 10,000mm hydrostatic head) or Ultra-Sil Compression Dry Sack (internal use - 2000+mm hydrostatic head). Both items are seam taped and have a roll-top closure to keep your sleeping bag dry on your adventures.
