Recently, I purchased a new backpack and was in need of getting a dry sack where I can stuff my clothes, etc. in to keep them dry in case of rain while on the trail. So I took a look at the Sea to Summit Ultra-Sil Drysack* for my next hiking, backpacking, and packrafting trips and here is a short review.

Sea to Summit Ultra Sil Drysack Review

The Sea to Summit Ultra Sil Drysack is durable, packs small and weighs only 50 grams.

I decided to go for the Cordura version of the Sea to Summit Dry Sacks. Even so, they are a couple of grams heavier than their non-Cordura brothers, I felt it’s worth having a sack that is a little more durable since my non-Cordura sack died already after the second trip. This 20 liters pack weighs 50 grams and has won the Backpacker Editor’s Choice award in 2006.


I have tested theSea to Summit Ultra Sil Drysack* on our trip to Sarek in Sweden and those dry sacks performed quite well to keep our clothes dry. Alternatively, I would also recommend the Sea to Summit Ultra-Sil Compression Sack which I prefer even more. It weighs 136 grams but you will be able to pack gear like down sleeping bag or down jackets really small.
