3D Nano Shell
3D Nano Shell is a protective layer between an outdoor enviroment which prevents condensation and external moisture affecting the soft, fluffy down of a Sea to Summit sleeping bag. The NanoShell fabric face is windproof and water repellent, while the 3D barrier of non-woven silicone encapsulated layer allows moisture vapors and condensation to pass through. If this condenses on the inside of the shell, the condensation (and any external moisture) cannot pass back into the down. Simply put, it'll protect the down so the down can keep you warm.

Sea to Summit ULTRA-DRY Down
ULTRA-DRY Down is a treated insulator for Sea to Summit sleeping bags. ULTRA-DRY treated down repels moisture, so when your environment is damp, your gear stands a much better chance. The down will retain its loft, dry faster and is even anti-bacterial and anti-microbial, improving their life span. When conditions are bad, your bag doesn't have to be.
