aquafree 2.5L 5L 10L 15L 20L Ultralight Waterproof Lightweight Dry Bag, Keeps Safe & Dry During Watersports & Outdoor Ultra Strong Silicone-Coated Nylon & Weighs Less Than 2 Oz.

Worked well on our trip to HI. I put our things in it to keep them dry and also to keep them out of the sand.

It's certainly Ultra Light. You can't get a sense for just how thin the material is from the picture. Too thin. Purchased as a Prime Lightning Deal for just over $10, but looking at it, it would be more appropriately priced as a package of 2/3 for $10.

We backpack a lot so these come in handy all the time

Love how light & stuffable this sack is. It’s downfall is that it’s supposed to be a dry bag & it is NOT WATERPROOF. Took it for a day trip on the back of my kayak. Some small waves splashed up so this “dry bag” was sitting in about 1 & 1/2” of water for about an hour before I realized it & emptied the kayak. A few hours later, I pulled our towels out but the bottom one was already soaked and part of the second one! Do not purchase if you actually want a waterproof dry bag!!

Needed something small but durable when on my paddleboard. This dry bag is fabulous!

kept everything dry, and that's all that I am asking of a product like this. Easy to use and lightweight

I have the 20 liter version of the bag. I didn't buy it to keep anything dry, but I got it to wash clothing while traveling. I've tried it out, and it seems to work pretty well. I'll be able to pack a lot less this summer.

I was surprised when the bag arrived to find how thin and lightweight it is. My expectation was a bag made of thick, rubbery material like the bags I have seen and used in the past. This bag is far more usable.To test the bag, I filled it with dirty clothes, rolled the top over 3 times, and closed the clip. The bag was puffed up due to the clothes and trapped air. Then with the bag under my chin, I squeezed it against my chest and felt no escaping air on my face.I then filled the laundry sink with water and tried to submerge the bag. This was very difficult and took all the force I could muster to get it under water. Because of the trapped air, it wanted to float.With maximum pressure still on the bag, almost immediately I noticed air bubbles coming out of one corner. I pulled the bag out, checked the contents and found everything still dry. This time I rolled the top 4 times before closing the clasp and forced it under the water. Again I saw air bubbles coming from one corner.After a few minutes I pulled the bag out. It was much flatter because of the loss of air, but the contents were still dry.It is possible that once all the air was forced out that water would have very slowly filtered in through whatever tiny opening in the seal that the air was escaping through, however, I am still giving the bag 5 stars. The reason is that I don't think this bag is intended to be forceably held under water for an extended period of time.Based on my test, I am confident the bag will keep the contents dry in the rain, in a boat, or wherever it might normally be used and that if it happens to fall in the water, it will float rather than sink unless loaded with rocks something heavy that wouldn't be put in a dry bag in the first place. Those are things I expect from this dry bag and it met all my expectations very well.The bag will also be very useful when I travel to hold any liquids that might possibly leak when traveling by air.Sample provided for testing and review.

A nice bag, would have been helpful to know the dimensions as 10L is a little on the small side to what I was expecting. Quality seems good, appears to be waterproof although not tested yet.

他の防水バックに比べ、薄く軽いーそこが良くて買ったわけだが、またそこが問題にもなり、自転車の荷台に括り付け縛っただけで、いくらか穴が空いてしまった。一度沢登りで使用して良さが分かっているだけに残念だけれど、この薄さでは、遅かれ速かれそうなるだろう。消耗品にしては高いし、もう少し丈夫なものが欲しいね。

渓流で濡らしたくない物を入れる目的で２０Lを購入しました。、防水のみ期待していたのですが泳がないといけない場所で身軽になるために、ベスト（道具入れている状態）を本製品に入れて、泳いだところ十分浮力あり、余裕で泳げました。当方体重60kgですが装備品＋飲み物（２リットル）を持っている状態でも十分浮いて気楽に泳げました。　きちんと３，４回開け口を折っていれば空気も抜けないですね。今の所、岸に上がるときに岩場にこすり付けても、穴が開くことはありませんでした。（薄目ですが、今後の耐久力に期待）中身もまったく濡れていませんでした。折りたたむと、手でにぎるれるほどのサイズです。２０Lでは意外と物足りなく、もうちょっと容量が大きいのを欲しくなりました。商品画像ではわかりませんが、肩にかけられる、取り外し可能なバンドが付属しております。（当方首から腰にかけて前にもって泳ぎました）※※※本製品、浮き輪にすることを目的とは思いませんので、泳ぐのはあくまで自己責任で気を付けて下さい。　防水性は抜群だと思います。

I bought this for general camping use but used it today for kayaking. I put my keys, money but luckily not my phone in it and guess what, it's not waterproof. It was full of water. Usually buy Karrimor dry sacs, they've never leaked.
