Description

For when dry matters as much as lightweight.

Keep your on-trail, on-deck, and on-board wares protected from the elements with the Sea to Summit Ultra-Sil Nano Dry Sack. Weighing scantly an ounce, this waterproof barrier might be silly light, but when it comes to repelling water and standing up to Mother Nature's wrath, it's über-serious.
  • Lightweight, durable nano sil nylon keeps your items bone dry without weighing your pack down
  • Hypalon waterproof roll-top closure seals out moisture for worry-free traveling and trekking
  • Fully taped seams prevent water from sneaking in through the fabric joints
  • A variety of size options let you dial in the perfect fit for the gear you want to quarantine
  • Only intended for use inside a pack or bag; not designed for paddlesports

Waterproof inside and out

  • Familiarity: I've put it through the wringer

I use this for two purposes: 1) As a wash bag for clothes when I travel and laundry service/laundromat are not available, 2) As a backpacking/hiking waterproof bag for electronics (phone).

The material feels a bit delicate, as it is see-through thin, and if given enough abuse, I wouldn't be surprised if it ripped or punctured. However, you would need to try in order to damage the bag beyond normal usage.

For all uses so far, it keeps water out, or for my example described above, keeps water in.

Highly recommended.

These things rule.

  • Familiarity: I've put it through the wringer

Use them fishing, beaching, MTB biking, hiking, canoeing, camping. Not responsible enough to keep sand and sea off my electronics without it.

SuperDuper!

  • Familiarity: I've put it through the wringer

This stuff sack is super light and keeps all my clothes for my trips completely dry. I have one in 8L and one in 13L. These are surprisingly durable for how thin they are!

A Great Product!

  • Familiarity: I've used it several times

I have used these stuff sacks in both backpacking and backcountry skiing for two years. My wife and I have about five each and we are very happy with them. They are waterproof and weigh about a quarter of what the stuff sacks they replaced did.

How do these bags hold up over time?

While I don't own this item [yet], I do have some experience with the material.
Keep it in your pack and don't put anything sharp-and-pointy in it and it should last forever.
If you need a bag that can be exposed to rocks and brush, or one that you can drop down a scree hill, then get something a little heavier :-)

I love these bags, it's my 2nd one, compacts down small, color is cute and very handy for electronics, snacks and more.

What size would I need for an adult mummy...

What size would I need for an adult mummy bag and smaller kids bag?
What about one for about a 3-day supply of clothes (summer hike - two pair convertible pants, 2 or 3 light weight shirts, 2 socks, one short, emergency light gloves/hat).

Thanks!

I use a 20L to carry a highly compressed sleeping bag, pad, thermal base layers, and a few other misc items, with plenty of room to spare, so I think the 20L could handle your two sleeping bags and some clothes. You could go for the 35L to be on the safe side - if you don't fill it up, the extra material rolls up into the top so it shouldn't take up too much extra room.
