Comments about Sea to Summit Ultra-Sil Dry Sacks (Assorted Color):
I use these for backpacking. If you find yourself raiding the pantry for freezer bags often, these are a great upgrade. Toilet paper, lighters, phone, etc. are all great uses for these bags. Between these and an eVent compression bag you really don't have to fool with a raincover. Boaters beware - these are so thin they really aren't durable for the long haul, but are great for lightweight backpacking.

Comments about Sea to Summit Ultra-Sil Dry Sacks (Assorted Color):
I love the 1L Sea to Summit Ultra Sil dry bag. I bought it originally because I needed something to put my cell phone and some extra cash in while cycling. I can rest easy knowing my phone is protected from sweat in my jersey. Since these are so lightweight, you aren't going to notice it at all. When I'm on the bike I don't clip the top since I don't need it to be completely waterproof, but I've also tested it in other situations with the roll top closed and can attest to the fact that this bag will not leak if fully submursed in water.
Since I had such a great experience with the 1L, I've started using these bags more frequently. I use the 1L to protect my point and shoot camera whenever there's a threat of rain or when I might drop it in the water. I plan to buy a larger one to keep my SLR safe as well.
