WOW! Just wanted some quick reviews on Motoport jackets, to decide to order the Ultra II stretch or Marathon stretch jacket..... and now know more than needed. FYI I live in Fairbanks AK where the temperatures range from 168 degrees F to 108F. Spend a -30 below day inside getting the answers and decided on the Marathon! I can use it for shredding the double black Diamonds (skiing) too! (needed there more).
