Why the Sea to Summit Ultra-Sil Compression Dry Sack?

2017 marks the year I retired my tired, 12-year-old 80L Jansport. I picked up a new Osprey Auriel 65L and realized that the 15L loss meant I would need a compression sack for my down sleeping bag. The Sea to Summit Ultra Sil Compression Dry Sack appeared to be the perfect solution. Maybe…

How I Tested It

I’ve used this compression sack a number of times, but the concept behind the compression sack is pretty simple. I’ve also had it loose in the car for a quick last-minute car camping trip. For the waterproof test, I sprayed the thing with a garden hose, on “gentle rain” setting for 30 seconds with my down bag in there to see how it would perform in wet conditions.

How it Performed

Overall, it does what it says it does, keeps the contents dry and vents out excess air when the system is compressed. At only 3.2 ounces (for the 14L capacity) you certainly don’t notice it. After being drenched by a hose, the contents (my precious down sleeping bag) remained perfectly dry. Water rolls right off of the bag itself.

However, I ended up having to purchase two of these. On a car camping trip, I left the Sea to Summit compression sack in the car and came home to find a hole slashed through it. I found this to be rather surprising, as it was simply sitting on the floor of the car. The fabric is also supposedly rip-stop, but it looked as if the rip had continued in several directions.

For best waterproofing results, fold the top over several times to ensure a good seal.

Best Uses

The Sea to Summit compression sack ensures your down bag stays dry, which is essential in the outdoors. I know people who use these to compress their tents and rain flies. Although I have yet to give this a whirl (since I only have one), I could see this being a highly useful compression sack. If you don’t mind wrinkly clothing, you could also use one for longer trips to compress your clothes.

Drawbacks

It was a disappointment to see this thing spring a rip so easily. Since it’s one of the few lightweight options for compression sacks, I’m giving it another try. However, if I find I have problems with the new one I’ll certainly be returning the product indefinitely and I will update this post accordingly. **Update: After returning and getting a new dry sack, I have had no issues after multiple uses.

Cost

$45 made me cringe a bit. However, as far as ultra-light, waterproof sacks go, the price is on par with others I’ve seen.

The Verdict

It certainly does what it claims to do and lives up to its lightweight namesake, after replacing the one that ripped, it works beautifully. I’d highly recommend this product to anyone who uses a down sleeping bag.

    Again, a review of something I’m looking for – thanks, Meg!
    On my previous trip, I used a general waterproof bag, which doesn’t hold air out well and can’t be properly smushed, so the sleeping bag bag was just huge altogether. It is so expensive, though! :-/

      No problem! I’m glad you liked the review. I used a general stuff sack for quite some time, and I found it just didn’t work with my new bag. The price definitely hurts, but if you’re looking to splurge, it’s worth it.
