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.

Easy to Seal
[This review was collected as part of a promotion.] The bag is very lightweight, visible, and easy to seal. I organize my backpack with these bags of different sizes and colors. A quality product.

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.

Perfect for travel
[This review was collected as part of a promotion.] I love that these bags are multifunctional. These dry bags are great for traveling with liquids, wet towels and more. I love using them. They are easy to clean. I hang dry to keep the water proof capabilities.

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.

Packaged to fail
I purchased two bags, a 20L and an 8L. Both came in condensed packaging where the company purposely folded the bag across a stiffer plastic piece onto itself to fit into their packaging. I attempted to straighten this piece so there was not a severe bend in it, but that caused it to crack, creating a sharp edge that the material would rub against, creating a hole. I returned the bags the next day due to this poor design in packaging that damages their product.

Lightweight & Dry
[This review was collected as part of a promotion.] These bags are extremely light weight, compact and durable. I wanted a bag for when I travel that I can stuff a lot of thing in that would be compact and this is perfect. I have not had a chance to test out how dry it keeps my clothes in a wet atmosphere, but so far it has been just what I was looking for.

Light and durable
I use this to store a change of clothes and to give some water resistance to my sleeping bag since it comes with just a stuff sack. It has held up great over many miles and is now my go to for outings.
