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

Sea to Summit sleeping bags come with either an Ultra-Sil Compression Bag or Nylon Compression Bag. 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 eVac Compression Dry Bag or eVac Compression Dry Bag UL. Both items are seam taped and have a roll-top closure to keep your sleeping bag dry on your adventures.
