        Comments about Sea To Summit Ultra Sil Compression Sack - 8 x 15:

        I can't believe I paid [$] for a stuff sack, but it works. Sizing is tough to figure out. The Medium size just fits a -15 degree down sleeping bag but not quite big enough for a -20 down/gore tex bag (old North Face Plover).Material is thin (hence light weight) but that is what I was looking for. Material is also slick, per description, for making sliding into pack easier.If the price were lower, it would be 5 stars.

        The little square pattern is not rip-stop nylon. Had a rip (my fault) and a hole (not my fault) from my second trip with it.

        The rip keeps expanding, due to lack of rip-stop. Expensive and light, good for gentle handling.

          Comments about Sea To Summit Ultra Sil Compression Sack - 8 x 15:

          I have two of these, an XL and a Small. The small crushes my 30 degree down sleeping bag to about the size of a large cantaloupe with EASE. The straps and the cap that goes over the opening are what does it so well. These are ultra lightweight From 2.0 oz (XS) to 3.8 oz (XL). Don't know how they could even make a lighter compression bag. Not too sure how well they repel water but gauranteed better than some stock compression sacks which are usually bad quality. These are high quality sacks for sure but gave four stars because I can't attest for long term durability but they seem like they will last a long long time.

          Very light, but tore the very first trip. I take care of my gear, and this did not stack up. If you're using it for something that is either too small for the bad, or compresses to a size too small for the bag it is okay. If you use it as a real compression sack buy something else. It is too thin to withstand the pressures. The weight is not worth the seam failures.
