TUNDRA TECH 
TUNDRA TECH® fabrics combine complete wind and waterproof protection with outstanding breathability, enabling you to stay dry and comfortable with fewer layers. This performance fabric is waterproof and breathable due to the polymer membrane fused between the outer shell and the lining. This thin durable membrane prevents wind and rain from penetrating the fabric, but allows moisture vapor from perspiration to escape through microscopic pores. The polyester shell is also treated with a durable water-repellent (DWR) finish so that water beads up on the surface and rolls off.
