Ultra-Sil Nano Dry Sack for Featherlight Dry Bag

The Sea to Summit Ultra-Sil Nano Dry Sack is a featherlight dry storage and organizing solution, designed for mountaineering, climbing, alpine adventures, and minimalist pursuits. Manufactured from durable 15D Ultra-Sil nylon with a smooth siliconized finish, this dry sack offers exceptional waterproofing with its reinforced 1,500mm waterhead rating.

The sack's waterproof seams are double-stitched, tape-sealed, and reinforced at stress points, ensuring maximum protection against the elements. A secure hypalon roll-top closure keeps moisture out, while the translucent fabric allows for easy visibility of the contents.

Featuring a low-profile, streamlined shape, the Ultra-Sil Nano Dry Sack saves valuable space within a pack or duffle. Its oval base resists rolling, adding to the sack's stability and convenience. A patent-pending field repair buckle can be replaced in seconds using a Phillips screwdriver, ensuring the sack's durability and longevity.

Available in seven sizes, from 1 liter to 35 liters, the Sea to Summit Ultra-Sil Nano Dry Sack can accommodate a wide range of gear, from small essentials to group equipment. The 20-liter model is an ideal choice for carrying a sleeping bag and liner, with open dimensions of 10.2 x 7.9 x 24.8 inches and a weight of just 1.3 ounces.

Backed by Sea to Summit's lifetime guarantee against defects in materials or workmanship, the Ultra-Sil Nano Dry Sack is a reliable and versatile dry storage solution for outdoor enthusiasts. Its featherlight construction and exceptional waterproofing make it an essential companion for any mountaineering, climbing, or alpine adventure, as well as minimalist pursuits where space and weight are at a premium.
