We bought these 8-litre dry bags for bike-packing. They are exactly as described: 8 litre dry bags, and will do exactly what we need them to do. while we bought them for bike-packing, they would be useful for a variety of uses when small items need to be compressed and/or separated from other items. Although they are not water-proof, they are water-resistant.

Bought this in two sizes: one to stuff my belay parka and the other for rain gear. Does exactly what it says! Extremely lightweight. Haven't really had anything get super wet, so I cannot comment on waterproof capabilities, but it seems like it does the job. A bit pricey, but otherwise great!

These dry sacks are so helpful for keeping my pack organized and my gear dry. I've strapped them into canoes and kayaks and filled up hiking and day packs alike with all the different sizes and am always confident that my gear is staying safe and where I want it to be! Buckles are sturdy, sizes are appropriate, shipping is fast.

I bought a number of these dry bags in different sizes and colors. I just got off a river in the Arctic National Wildlife Refuge and it rained every day, except ONE! I was rafting and used a large, tough dry bag, lined with a large Ultra Sil dry sac ... then organized my gear into these smaller bags. I have found that redundancy in the field is a good thing! It was so nice to reach in and grab a bag, knowing what was inside!!! All my clothing and gear that needed to stay dry DID. As I pulled individual Ultra Sil Dry Bags out for different items, the other things in my pack stayed dry. Organization and dryness - what more could I ask for!One thing I noticed is that I don't need as large a dry bag as I thought I did, as you can compress items, and save space. For ...

Organization and dryness - what more could I ask for!One thing I noticed is that I don't need as large a dry bag as I thought I did, as you can compress items, and save space. For their intended purpose, these Ultra Sil Dry Bags hold up very well. You will always want to protect them with a heavier weight, sturdy bag on the outside. Also, very light! Great product.
I bought a smallish one a few months ago to use as a bear bag and it is perfect! Ultralight and it closes in a way that is waterproof and can squeeze our air. I just recently got another one (large one) to replace a pack liner & will be using it on my next trip. So far I have used it once in a day pack, and it worked well. Highly recommend!
I was astounded at how light this bag was. This is exceptionally thin material, is meant for clothing or non-electronic items that you want to keep dry or away from other items. It is not at all like the rubber-type dry bags that you may be used to and that weigh considerably more. The 8L size is still quite small. It would be ideal for packs where weight is an issue and will be very easy to carry when travelling. Not for keeping items dry on a boat. A very inventive item.
I purchased two of these dry bags to go with my Trek 1120 bike's custom rear rack. These bags are extremely well made and are very high quality. They weigh almost nothing and are very strong. We went for a family bike ride today and I had both bags fully loaded with snacks for the kiddos and some extra warm clothes. They worked perfectly and have a clever closing mechanism. I love these bags!
Used these for a while now in different sizes. Use them both when i travel and backpack, usually keeping my spare clothes in a 13L bag, using the 1L bag for electronics and the rest how I fit them. Pretty light weight and have stood up to a completely wet backpack.
For the last year or so I've used these and the slightly thicker 'light' version for kits around the house and on the road. Haven't had one fail yet and the removable buckle fits both kinds if needed. Pricey but works great. On sale 25% a few times a year.
Slippery fabric, helps to stuff it in the bag, and feels durable. Weakest point is definitely the buckles. One came loose, luckily has a small enough screwdriver to repair it.
