Sea To Summit Ultra Sil Dry 20L

Product description Sea to summit Ultra Sil Dry 20L

The new Sea to Summit Ultra-Sil® Dry Sacks are more than 50% lighter than our super popular Dry Sacks.

They’re made of Siliconized Cordura®, which is one of the lightest and toughest waterproof nylon fabrics available.

Now you don’t have to choose between keeping your gear dry and keeping it light.


- 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

- Nearly transparent allowing good visibility of the contents

- All seams are double stitched and tape sealed

- Smaller sizes have flat bottoms, others are round

- Colors: kiwi green, sky blue and orange

Proper Use:

- 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.

Good product


Quality product. The breathless material cuts the back and the backpack is difficult to pack back into its bag, but the product works well.

Best backpack ever!


Great tiny pack. Weighs next to nothing. You can stuff it.

Perfect portable daypack


I usually carry a water bottle or two, a jacket, toilet paper, and lunch. The pack handles those items easily and the shoulder straps are comfortable for that load.

Perfect day pack


This bag is great! It stuffs into its built-in bag and is very tiny, small enough to fit in a purse or cargo pocket with ease.

Very compact, and useful!

Perfect as auxiliary backpack


With its 20 l its compression bag is ideal for carrying in the backpack crossing and use it to attack a summit and even climbing routes of various lengths, with minimal material for these occasions (water, food attack, frontal, jacket, etc, etc.) Very tough.
