Ultra-Sil Dry Bags are an ideal dry bag for backpacking, travel and cycle touring and here come in a set of three: a 3-litre, a 5-litre and an 8-litre bag. They are made from bluesign®-approved ultra-lightweight, waterproof 30D Ultra-Sil with CORDURA® yarn fabric that is also semi translucent so you can see what gear you have packed inside. Other features include a roll-top closure and taped seams to further keep moisture out and oval bases so the bags don't roll away on a slope and to make packing more efficient.

The body of the dry bag is waterproof enough (2000+ mm hydrostatic head) for use as storage inside a backpack or duffle. However, for water sports or on its own, Sea to Summit recommend dry bags with higher hydrostatic head ratings.

30D Ultra-Sil: an incredibly lightweight yet durable fabric used in a large number of Sea to Summit products. This 30 denier Nylon is made with CORDURA® yarns for strength, woven into a ripstop pattern. Two versions of the fabric are used:
Water-resistant products (such as the Ultra-Sil Stuff Sacks) are siliconised on both sides for ultimate packability
Waterproof products (such as the UltraSil Dry Sack are) siliconised on the outside and PU-coated on the inside to allow seam taping.
Both versions have a hydrostatic head greater than 2000mm, which makes them more than adequately waterproof for the types of environments they are intended for.
CORDURA® is a special type of nylon yarn used for its strength. These yarns are used in two different product areas: In the siliconised Ultra-Sil fabrics used in Ultra-Sil Dry Sacks, Stuff Sacks, Compression Sacks, Pack Covers, Travelling Light and Travel Essentials products and in the foot section of the extremely tough eVent® Quagmire Gaiters.
bluesign® approved: The bluesign® system is the solution for a sustainable textile production. It eliminates harmful substances right from the beginning of the manufacturing process and sets and controls standards for an environmentally friendly and safe production. This not only ensures that the final textile product meets very stringent consumer safety requirements worldwide but also provides you confidence you'll acquire a sustainable product. Those operating sustainably - meaning conserving resources and reducing the environmental impact to a minimum - also act responsibly and innovatively. Wanting to produce sustainable goods though involves a detailed examination of all materials and processes used as well as the impact of the production on the environment. Only this holistic observation, which starts well before the actual production, will guarantee a final product that is harmless to human beings and the environment. The standard covers 5 principles:
Resource productivity: defines the ecological and economical goal to produce textile products of maximum quality and added value, using a minimum amount of resources as well as causing the least possible environmental impact.
Air emission: air emissions need to comply with strictly controlled emission limits along the entire production chain. Optimising the energy flow as well as using low-emission components reduces the CO2 load, implicating active climate protection.
Occupational health and safety: the health and safety of employees in the textile industry has to be safeguarded by strict guidelines. Weak points occurring locally must be detected. In accordance with the risk potential of the deployed chemical substances, corresponding occupational safety measures are mandatory.
Water emission: control aims at feeding back purified water into the natural cycle and causing the least possible pollution of rivers, lakes and seas. This can be achieved by the use of ecologically harmless components as well as by optimising production and wastewater treatment processes.
Consumer safety: includes not only the mandate for high-quality textile products without health risks, but also the assurance that all of the principles of sustainability are consistently implemented during the production process.
