Sea to Summit Ultra-SIL Stuff Sack, Ultralight Outdoor and Travel Storage

Handy item, good For storage of jackets.

Great brand, they make great products. This is the perfect size to stuff my rain jacket and pants in, bright color is easy to see in the bottom of my backpack.

Perfect replacement for lost stuff sack for Uniqlo down coat

I bought a 3pk last year and love these sacks. I wanted one more this size. They are the best stuff sacks I like the water resistance.

I cannot say enough good things about this bag. I bought it in January 2015 (a year and a half ago) and have been using it as my gym laundry bag every day I go the gym (let's call that ... 3x a week). I jam my nasty stinky damp gym clothes into this bag, then leave the bag in my alternating blazing-hot/freezing-cold car all day at work, then come home, dump the stinky clothes out, and load fresh clothes into it for the next day. I have never washed this bag. It does not smell, and it has never leaked gym-clothing-smell onto my next-day-clothes. It does not let smell leak out -- my car hasn't suffered from gym-clothing odor since I got this bag.The large is maybe a bit excessive size-wise for dirty gym clothes, but considering how lightweight the bag is and how little space the extra bag fabric takes up, why not get a larger one? The large would work well as a laundry bag for a weekend trip, but you might want a bigger size as a laundry bag for a longer trip. Also, the gold color is fantastic. I'm always paranoid that I'm going to forget my clean clothes at home, and seeing the bright gold blazing out of the depths of my gym bag is very reassuring.------Also, because the way they've listed the sizes is awful and bears very little resemblance to the drop-down of size options, here's my best guess at corresponding the volume/dimensions with the listed sizes. No promises these are correct! Use at your own risk:XXS is 2.5 L (4" x 8.5"), weighs 0.4 ozXS is 4 L (5" x 12"), weighs 0.5 ozS is 6.5 L (6.5" x 13"), weighs 0.6 ozM is 9 L (7" x 15"), weighs 0.7 ozL is 15 L (8.5" x 17"), weighs 1.0 ozXL is 20 L (9.5" x 19"), weighs 1.2 oz.XXL is 30 L (10.5" x 23"), weighs 1.4 oz

Sea to SUmmit makes great items and this Ultra-Sil Stuff Sack is no different. This is the 3rd one I have purchased within the past year. I use them for backpacking and organizing some of my items that might get wet or those I want to keep dry. Currently the XXS green one is used to store my hammock winter cover and works perfectly. The ultrasil does a great job keeping items dry. I have used the sea to summit pack cover with the same material and my pack was completely dry except where it was exposed to the elements.Overview:Pros:-Lightweight, not as light as cuben fiber though (however they are a lot cheaper than cuben fiber)-Waterproof-Keeps odors from escaping (I use it as a bear bag and you can't smell any of the food when it is closed up-DurableCons:- Somewhat expensive-No event system to let trapped air out however this is true for most regular stuff sacks and just requires skill in packing/closingOverall: I would recommend this stuff sack to anyone who wants to keep their items dry, or is looking for a good way to keep items organized.

A 2 person tent fits perfectly in this sack. When you pack up a wet or dewy tent on the trail, this sack keep the water off the rest of your gear. Love it!

I had ordered a couple of the Equinox Bilby Stuff Bag which I really likes, but figured I would check out these bags. The material is a lot thinner on this that the Equinox Bag, which was OK as a very lightweight bag, and this is probably the nature of the Ultra-SIL material. What killed it for me was the very small clip that secures te string as you close the bag. It is lierally about a 1/4 of the size of the one on the Equinox Bag and will pull through easily when the bag is stuffed. This bag seems well mde, but I need a bag that is going to stay closed when I tighten the string.

Faultless

Great bag, just right to fit a small down jacket in to it.

OK but need dimensions of sack the XL sack was not very big at all. I have had to use for something else

A useful bag but smaller than I thought it would be.

I give this 4 stars and not 5 because I have a 20l bag by a different supplier that is the same size as the 30l bag from Sea to Summit. So there seems to be an issue with the sizing. But in all other respects this bag does exactly what the advert says. If I could guarantee getting the correct size I would not have a problem buying from this manufacturer again.
