The Sea to Summit Ultra-Sil Dry Bag 8L is an ultra-light and waterproof dry bag for organizing and protecting clothing, toiletries and other small equipment inside a backpack, bike bag or suitcase.

The eight-liter model weighs only about 30 grams and measures approximately 46 × 17 centimeters. The minimal weight and packing volume make it especially useful during hiking, fastpacking, bike tours and trips where every gram counts.

Ultralight 30D Ultra-Sil Cordura

The stuff sack is made of 30D Ultra-Sil® Cordura® nylon. The strong Cordura fibers are woven in a thin ripstop pattern that provides a high strength-to-weight ratio.

The exterior is siliconized to repel moisture and create a slippery surface that slides easily between other gear. The interior has a waterproof polyurethane coating that allows the seams to be taped. The material is semi-transparent, helping you identify the contents without opening the bag.

Taped seams and 2,000 mm water column

The Ultra-Sil material has a stated water column of over 2,000 millimeters. The seams are double-stitched, reinforced at stress points and sealed with waterproof tape.

The construction protects the contents from rain, snow, condensation and other moisture inside the backpack. However, the very thin material is more susceptible to punctures and abrasion than Sea to Summit's stronger drybags. Therefore, avoid sharp objects and direct contact with rocks, gravel and other rough surfaces.

Roll closure with Field Repair Buckle

The opening has a reinforced Hypalon edge that does not absorb and transport moisture into the pack. The edge should be rolled at least three full turns before the buckle is closed.

The replaceable Field Repair Buckle is 15 millimeters wide and has two stainless steel pins. If the buckle becomes damaged, it can be replaced without the need to split or re-sew the strap.

Convenient size for smaller equipment

The eight-liter volume is suitable for underwear, socks, gloves, hats, hygiene items and other small accessories. The cylindrical shape and round bottom make the bag easy to place vertically or horizontally in a larger backpack.

The slippery exterior simplifies both packing and unpacking, especially when space is limited and several packing bags need to be placed close together.

For internal storage

The Ultra-Sil Dry Bag is primarily designed for internal storage in backpacks and other bags. It is not intended for paddling, general boating use, or situations where the dry bag may be submerged.

The material and taped seams are waterproof, but the roll closure is not pressure-proof. Electronics and other particularly moisture-sensitive equipment should therefore be double-packed or placed in a waterproof hard case.

Use

Place the equipment in the bag, leaving enough space for the roll closure. Squeeze out any excess air, align the sides of the opening evenly, and roll the Hypalon edge at least three full turns. Then snap the buckle shut.

Avoid overfilling the bag, as this can make it difficult to roll the opening properly. Pack sharp and angular objects separately so they are not directly against the thin material.

Cleaning and storage

Wipe the packing bag with a soft cloth, lukewarm water and, if necessary, a mild detergent. Do not use bleach, solvents, machine wash or tumble dry.

Allow the bag to dry completely with the opening rolled out before packing it away. Store it in a dry place and away from prolonged sunlight, open flames and strong heat. Regularly check the material, seams and roll closure for small holes or other damage.
