Rated 4 out of 5 by from Super Compression, Super Light 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.

Rated 5 out of 5 by from Perfect size to pack into 22" carryon I had to pack a weeks-worth of underwear and socks into a 22" carryon. The "large" size I already had was too big, but the "small" size was perfect. Filled it, cranked it down, and it fit perfectly into the luggage. I used the large one to hold items like shirts, pants, and shorts. They make good laundry bags too while traveling! These sacks are durable and lightweight so you don't sacrifice much by bringing them along on trips. I just wish they were more squared off so they fit better into rolling luggage. Round objects leave small open spots - a waste of valuable packing space. Also, most clothing isn't very round so squares and rectangles would be a good line extension. If they made them, I'd buy them.

Rated 5 out of 5 by from Pack space extraordinaire I have a small for a 32 degree down bag and a XL for a 15 synthetic. Both compress the bags as small as possible. I use a Flash 50 pack and water bladder so this hedges against rain or bladder leaks while giving me more space in the 50L bag. Whatever few ounces these way are made up by having more pack space and thus less need for a bigger and heavier bag. I've beaten mine up good and sat on them and they are solid. I also use these as a pillow when backpacking; fill with clothes and then pull a fleece pillow case over it. Keeps any odors out and saves more weight.

Rated 5 out of 5 by from Wow I ordered this stuff sack in size small. Other reviewers suggested that you can fit a lightweight down sleeping bag into the small. When I received it, I was incredulous that my entire sleeping 20* bag would fit into such a small package without tearing the stuff sack. But I had no trouble stuffing my down North Face bag into this thing. In the end, my sleeping bag now takes up less than half the space in my pack than it did with its manufacturer's stuff sack. Highly recommended.

Rated 5 out of 5 by from use them all the time I'm writing this review because there have been some negative durability/construction reviews. I have two 30L compression sacks that I use for my synthetic sleeping bags – I put a 20-degree bag in one and a 40-degree bag + double liner in the other. I really have to mash the 20-degree bag into the sack, punch in the sides, and then compress it all the way down to the end of the straps, usually by kneeling/sitting on it, to get it into the dry bag I use in our portage pack - and I've done so easily 100 times. With such rough handling, I always expect something to pop, but so far, not a ripped seam, not a stitch broken – they're as good as new. I also have a 6L and a 10L that I use backpacking, but nothing has taken the abuse of the 30L sacks. One of these days, we'll get down sleeping bags and maybe I won't have to wrestle with them so much! I always try to pack them so that anything hard is packed in the middle of the sack so it won't poke the fabric when compressed. I've also found that compressing the sides part-way progressively around the sack keeps the load even and prevents the sack from becoming lopsided/lumpy. They are a bit pricey, but if you're looking for lightweight compression sacks, these are whisper-light and they've held up great.

Rated 1 out of 5 by from Do not buy 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.

Rated 5 out of 5 by from Squish that bag This bag works great in compressing the sleeping bag to a small nugget that easily fits into my backpack. I have an extra long, extra wide down bag that barely fit into the sleeping bag compartment of my pack when in the standard stuff sack. This lets me put bag, inflatable pad and small pillow in the compartment with ease. Sack also easily accommodates a set of sleeping shorts and tee to keep handy. Have not had to test the water resistance yet but was a bonus feature for a down bag.

Rated 2 out of 5 by from Great sack but... Bought this compression sack and used with my North Face Casaval(regular)bag before a two day section hike of the AT. All went well until the second day the sack tore at the seem while compressing my bag. I had heard Sea To Summit gear was of good quality will have to look into other brands possibly for a better quality compression sack.

What size would you recommend for a DUNNOCK™ COLD WEATHER SLEEPING BAG

Asked by: fitbrown25
That sleeping bag is too large for any of the Ultra Sil Compression Sacks we are stocking. That sleeping bag is not really meant to be compressed and may need a sack as large as 35-40 liters.

I have a Nemo Canon -40 bag used for expeditions. It has a stated compress volume of 18L. Do you think I can pull off a 20L bag or reach up toward 30L?

Asked by: NoBallGames
Compression stuff sacks should be purchased based on the standard stuff sack size. In this case, a 30 liter compression stuff sack would work.
