The IWOM eliminates all of your traditional jacket and pant heat and scent release points. The chest zipper goes all the way up to your cheek and removes the heat release that you normally would find at the head area. The wrist gaiters at the ends of the sleeves ensure that the heat doesn't just flow out the sleeves. The waist area where you normally would have the jacket and pant overlap is eliminated all together. And finally your feet are totally enclosed capping off the ultimate scent and heat containment system.
With a top to bottom zipper the IWOM Pursuit XT completely opens up for easy access for the user.
