2D NanoShell is the lightest, most breathable water resistant shell fabric in Sea to Summit's range. The Nano DWR treatment is highly durable due to the tiny particle size of the repellent allowing a greater quantity of particles to attach to the fabric fibres and adhere better than larger particles. The treatment has been designed to optimise breathability while providing a windproof and water repellent shell protecting the down from external moisture.
