The outer is constructed from Sea to Summit's 3D NanoShell which provides both water resistance and condensation management to protect the down fill the effects of moisture.

Contoured Mummy Shape

Sea to Summit's contour mummy shape has been sized generously across the shoulders and chest to allow space for wearing extra layers in extreme conditions. There is knee room to allow turning and the boxfoot is oversized to give room for boot liners.
 
Ultra-Dry Down
 
Ultra-Dry Down has a water repellent treatment protecting the down from moisture and condensation. The water repellent polymer treatment vastly improves the downs water repellency without effecting it's weight or loft performance. Ultra-Dry Down retains over 60% more loft and absorbs 30% less moisture when compared with untreated down. This not only helps insulate better in wet conditions but means Ultra-Dry Down bags dry much quicker too. The treatment also stops bacterial and microbial growth, making the bags more hygenic and giving them a longer life span.
 
3D NanoShell
 
3D NanoShell uses a two layer construction to protect sleeping bag down from both external moisture and condensation from vapour leaving the users body. The outer layer is windproof, water repellent and breathable. It acts to protect the down from external moisture. The inner layer is a thin non-woven silicone encapsulated layer. As vapour from the body moves through the down and comes in contact with the shell, if the temperature is low enough it will form as condensation on the inside of the shell. The hydrophobic properties of the inner layer traps the condensation close to the outer shell thus preventing the down from getting damp.
