These dry bags do exactly what they say. On a rainy day hike they kept my spare clothes completely dry. Also useful for traveling to keep organized.

This Sea to Summit bag works great. Holds a lot of stuff while keeping it dry. I've gotten the bag wet a few times now and everything inside stays perfectly dry. The bag is very easy to clean and made from quality material.

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!
A top line product. When Canoeing on trips compression dry sacks are the first line of defense to keep your sleeping bag, clothes and tent dry when you go for an unexpected swim. Also use this to store your dry suit over the winter to keep the gaskets from drying out.
I bought this dry bag for a recent week-long camping and canoeing trip. The bag was large enough to fit two sleeping bags—and worked perfectly to keep them both dry both in transit in the canoe and during a day of heavy rain. 10/10 would recommend!
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.
I bought the 20L and 13L dry bags and am glad I did! These are the perfect edition to my pack, my bedding (sleeping bag, sleep pad and my dogs blanket fit perfectly in the 20L and the 13L I have for 4L sea to summit water cell X, the 13L is a perfect fit and I can roll it down several times which makes me feel better about my water bag not leaking inside of my pack (already had the water leak into the bag and none of it escaped the dry sack. 10/10 would recommend and have already recommended
