Evolution by Viking Tempest Unlimited

Waterproof/Breathable

Viking uses the most globally recognized Hydro-static Water Pressure testing method – AATCC 127 to qualify our fabrics as being waterproof. The test material is subjected to steadily increasing water pressure on one face until water penetration occurs on the opposite face in three separate locations. The minimum standard for Viking is 11.2 psi (pounds per square inch) or 784 mbar. This may generically be called 8,000 waterproof.

Trilobal Ripstop Polyester

Trilobal Polyester utilizes triple twined polyester thread to create a cross section of fibers at regular intervals to form cells. These cells significantly increase the tensile strength of the garment over regular knit fabrics, effectively preventing tears from expanding to the next cell, while increasing the cut, tear and abrasion resistance of the garment.

Stormblaster Hood

The Stormblaster hood system reduces wind and rain exposure up the back of the jacket, while orienting the front close to the chin and cheek area. It has a safety “Tear Away” design, making it easy to remove and attach. Standard hoods are traditionally attached with hook-and-loop fasteners or buttons, leaving gaps that could allow water to travel up and around the neck area.
