Description

An excellent balance of durability, weather-resistance, and weight, the award-winning Sea to Summit Ultra-Sil Dry Sack is a reliable, ultra-lightweight option for organizing and protecting backpacking gear.

The dry sack’s Ultra-Sil 30D siliconized Cordura nylon fabric is highly durable and is coated for high water-resistance. Fully-taped seams further ensure weather protection and reinforced stitching bolsters strength. A Hypalon roll-top closure provides wide-open access to the sack’s interior but battens down the hatches by using an internal stiffener to create a secure seal. Delrin buckles emit a positive “click” when connected to confirm that you’ve properly protected contents. Oval shaping at the bottom of the dry sack provides structure and makes packing easy.

The Sea to Summit Ultra-Sil Dry Sack is available in your choice of colors and 1L (4.3" x 9.4"), 2L (5.1" x 11.4"), 4L (5.9" x 13"), 8L (6.7" x 18"), 13L (8.6" x 21"), 20L (10" x 24"), and 35L (12" x 27") size options.

  • A Backpacker magazine Editors' Choice Award Winner!
  • Super compact and ultra lightweight
  • Made of Ultra-Sil nylon, a polyurethane coated siliconized Cordura for ultimate waterproofing and maximum durability
  • Non-wicking Hypalon roll top closure with stiffener at the top for a better seal
  • Soft and flexible with a slippery finish for easy packing
  • Translucent fabric allows good visibility of the contents
  • All seams are double stitched and tape sealed
  • Any roll-top dry sack must be closed properly to ensure water can't get in. Begin by folding the Hypalon strip down first and be sure to have at least three rolls before closing the buckle.
  • Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
  • Ultra-Sil Dry Sacks should only be used to store sensitive electronic devices when used in conjunction with another, heavier-duty dry bag - the double bag method. For maximum protection of electronics the use of a waterproof hard case with a mechanical seal should be considered.
  • This product is not intended for boating or marine use.
  • Intended for use inside a bag or backpack

Nice lightweight drysack

Likes

Very lightweight with solid construction and good materials. The sil nylon in this bag seems a bit more durable than other types of silnylon.

Dislikes

Not sure about the durability of the buckle as I often break these. To be determined how well it handles wear.

Take my review with a grain of salt

Likes

This has incredible packability. If you are looking for an ultralight dry bag to keep clothes or other good dry, this is likely a great choice.

Dislikes

Ok, so I will admit that I did not do any testing of the water resistance of this product. However, I was going to use this as part of a "double bagging" system for a DSLR camera and a few lenses and the thinness of the material made me hesitant enough to return it for one of the thicker Seas to Summit dry bags. I'm sure it works great, but I didn't want to risk expensive equipment with something that felt like it would not handle abrasion very well. Again, I did not use the product, so this is more of a "gut feeling", but it's my impression.

Use as a waterproof food bag.

Likes

I purchased the 13 Liter bag to hold all my food. It's waterproof, and the perfect size for holding 5 days of food with room to spare. I use a carabiner and a line to hang it out of reach of pesky critters at night.

Dislikes

Nothing.

Seems high quality and as described

Likes

Out of the box it seems airtight and waterproof, seems durable and very light. The 13L should be big enough for 5+ days of food.

Dislikes

None so far

Seem very thin.

Likes

This product is very lightweight, even the top and clip. The bags are all smaller than I'd thought. I wish Backcountry Edge would list not just the volume, but also the dimensions on their site. I don't know how durable they are going to be, and who cares if the fabric is lightweight if it rips or tears with use, because it won't remain waterproof if torn. I am not a rough person, but time will tell on this one.

Dislikes

Very thin

Just as advertised

Light weight. Holds a surprising amount of clothes. Haven't got to test out how water proof it really is but hope I don't have to.

Great choice.

Likes

Truly waterproof. Light. Durable. The way in which in rolls closed makes for easier hanging on a bear pole.

Dislikes

Nothing.
