An alternative to housewrap is a product called Zip board. Coastal areas suffer from high winds that can blow off the siding — and the Tyvek along with it. Zip board works as sheathing and won't blow off. Like Tyvek, it is engineered to allow moisture vapor to travel through, allowing walls to breathe and dry out.
Because it is waterproof yet breathable, Tyvek also makes great car, bike or grill covers. It is used for protective clothing, industrial packaging, graphic applications, medical fabrics and even clever pendant lights like this one.
