Rated 5 out of 5 by from Love these stuff sacks!!! These stuff sacks are great. They come in different sizes, have different colors so you can remember exactly where something is. They also have a siliconized coating which will do a good job of keeping it dry, although water can get in through the opening of these bags because they are not truly waterproof. They are extremely lightweight. They are very thin and I assume puncturing could be a problem with pointy objects, but so far I've had no such problems. I have several to organize my smaller gear such as cooking gear, personal gear and such. They are not compression sacks just to make that clear, but if you are looking for a stuff sack these are the ultimate find.

Rated 5 out of 5 by from Great Product I got the Sea to Summit Ultra-Sil Stuff Sack to replace the stuff sack I lost from my down jacket. I needed to store my jacket in a climbing and backcountry ski pack. The main purpose is to prevent the jacket from ripping when stored next to a shovel/probe or climbing gear. So far I have been very happy with the Ultra-Sil Stuff Sack. I am not worried about my coat tearing while in the pack because of the durability of this product. I also have more room in the pack for extra food and gear than before since I was able to select the appropriate sizing. Yes this is not a dry bag and the Ultra-Sil Stuff Sack will let in water, but that is not the intent. If I wanted a dry bag I would have purchased a different sea to summit model sack.

Rated 4 out of 5 by from Good Stuff Sack Very nice stuff sack, exceptionally well sewn. Slippery enough to slide into pack without extra effort. However, can't understand why sacks sized for sleeping bags don't have a dust flap. I was not expecting a dry bag closure, but I'm old school enough to expect a dust flap on anything over ditty bag sized.

Rated 5 out of 5 by from Amazing! I have two of these bags, and love them both. They are extremely lightweight, very strong, well stitched, water-resistant, and are all around well made. No, they are not water-proof, but they are not supposed to be. I stored around twelve pounds of food in one of these bags and it held up great.

Rated 5 out of 5 by from Lightweight, Water Resistant I've used two of these sacks for the past few years, and they work perfectly. They are very lightweight, and perfect for backpacking. I use one for my sleeping bag and one for food. They are water resistant, not waterproof. I have a down sleeping bag, and if the bag gets splashed, or my backpack is wet, it will keep the sleeping bag dry. It will not however, keep its contents dry if submerged. Overall, this is a great choice for lightweight backpacking.

Rated 4 out of 5 by from Versatile little bag Happy I bought this 16L stuff sac. Tough and waterproof! Did I mention light weight???? I used this as a bear bag on a recent camping trip in the Catskills and it worked like a charm. I'm sure I'll think of other things to use this for but it held up overnight in light rain and kept all the water out despite not being labeled as a dry bag.

Rated 4 out of 5 by from Great bag with a lacking tab After nearly two years of using the 15L version of this bag for hanging food on backpacking trips, it has held up nicely. Unfortunately, sometime in the middle of the night on my last trip, the hang tab ripped and when I went to retrieve my food in the morning, the bag was on the ground. Thankfully no critters got to it before I did, but I'm pretty disappointed with the tab. I need a new hang bag now, but I'm hesitant to get another of these for the same job.

Rated 5 out of 5 by from super nice This sack is the snizzle. The bag is so light weight it is almost nonexistent. I use for camping blah blah blah and also when I travel to keep dirty laundry separate. Get the xl unless it is for something specific because it weighs nada.

what size would owners recommend for stuffing an XL rain or nano pull jacket into?

Asked by: Michaelcs
Some jackets are much more packable than others, so it is hard to determine which size is best without knowing the packed dimensions of your jacket. We recommend packing your jacket as small as you can and comparing the measurements of the packed jacket to the dimensions of the stuff sack in order to determine the best size.

which size is best easiest to use for a sleeping bag

Asked by: kogentry
Most 3 season sleeping bags have a stuff sack size of 8x18. The appropriate stuff sack size will vary depending on insulating material, sleeping bag length, and other materials.
