Why We Like The Sea To Summit Ultra-Sil Dry Bag
Lightweight and waterproof, the Sea to Summit Ultra-Sil Dry Bags are made to keep our gear dry and organized inside a backpack or travel duffel. The translucent fabric lets us see the contents easily while the roll-top closure compresses our belongings and protects them with a watertight seal. These bags are not submersible and not intended for paddling and watersports. However, their 2K waterproof rating and seam-sealed construction keep our clothes, sleeping bags, electronics, and other gear dry when we're out backpacking, bikepacking, or traveling.

UL Dry Bag 3L
[This review was collected as part of a promotion.] This 3L dry bag is perfect for organization while backpacking. I used to think I didn't need an organization system, but it makes all the difference for minimal weight. I store my toiletries, electronics (cables and battery pack), and other personal care items. Would highly recommend to anyone considering!

Durable and UL… magic
[This review was collected as part of a promotion.] Does exactly what it’s supposed to do. Keeps things dry while being incredibly light. There are other “lighter” options out there that I have tried. Nothing comes close to the durability to weight ratio that they have achieved with these dry bags.

Perfect Dry Bags!
[This review was collected as part of a promotion.] My husband and I are currently in the midst of a multi week backpack trip on the coast of England, where we’ve had some significant rain and heavily dewey nights. We’re using three ultra-sil dry bags inside of our backpacks to keep everything nice and dry. These bags are indispensable. They’re very light weight. The fabric is nice and smooth, allowing you to slip them in and out if your backpack very easily. We’ve used them for about a month and they still look just like new!

Biggie Bag of Magical Treasure
[This review was collected as part of a promotion.] Surprisingly durable! Used it for the entire Superior Hiking Trail thru hike as my hang bag for my food. Then used it backpacking in Colorado as my dry sack for sleeping bag and pad. Wicked light, wicked simple, and overall a good product. Great stuff.

Ultra sil 4 litre dry bag
Unfortunately, perhaps user error, the top of the bag ripped off when I tried to stuff clothes in it. Not meant for putting much strain on it.

Great size
[This review was collected as part of a promotion.] This 8 liter fry bag is a great size! I use it on my kayak to keep my stuff dry while out on the lake. It’s not too big and not too small. It’s sturdy and feels like it will last a very long time. The color is true to color.
