IconX Heated Core pant is the ultimate combination of next to skin heat and performance. It’s no secret that you can stay in the field longer when you keep your core warm. The biggest enemy you face during late-season hunts is cold. Cold impacts your performance mentally and physically. It can affect your body’s ability to stalk across a ridge or to pull to full-draw smoothly. The key to winning the battle against cold is maintaining your core temperature. Our heated core pant utilizes undetectable carbon-fiber heating elements that crisscross your lower back and tops of thighs to distribute constant, efficient, and compelling warmth. With three levels of heat available at the push of a button, you’re in complete control of your comfort. Our IconX fabric adds unparalleled wicking and muscle support to complete the package. Wear the Heated Core pant under your IconX top or Merino Wool baselayers on the coldest of days. You’ll remain warm with no bulk and experience total freedom of movement, and stay in the hunt as long as it takes to get the big game you’re after.

Awesome Gear

Have the complete set, pants, vest & shirt. extra batteries always a good idea. Set works great. I find myself having not to turn on most of the time, when I do turn on, it's not for long, I do wear a light base-layer under them, I have yet to use up a fully charged battery. Product works as advertised. Quality product. I am 6' 240Lbs & wear the 2X pant / shirt, 3X vest and it is slightly loose fitting. Fit is true to size & is not restrictive. Great for those frigid day sits. Happy PA hunter. Highly recommend.

Great Product

First, the customer service at Pnuma is top-notch. I needed the long-sleeve thermal within two days so I called customer service and they were awesome. Got directly connected to someone right away and they ensured I would get the thermal within 48 hours and even put a rush delivery on it. I went out muzzleloader hunting for mule deer in western Nebraska during the December cold snap of -40 to -60 below zero and the thermal worked great. I didn't even need to turn it on until I was done walking/cutting off the herd where the buck was, but once I did power it up, it was instant heat. It's very comfortable also and fits like a dri-fit compression shirt. I am 6'2" 205-210 with muscular build and the Large fits perfectly. I also used the Waypoint pant and matching jacket on the hunt and I'm impressed with their products thus far and will be using them for years to come. Thanks, Pnuma!

Totally worth the money!

Best investment I've made for late season Wisconsin hunts and ice fishing.
Buy extra batteries! Only complaint is the battery life and position they sit on top of eachother which creates bulk thats uncomfortable while sitting, also the connection lenth and plug...the lenth should be longer and use a usb plug so you can use a charge pack positioned where you want and 20,000mah would last all day long. Other than that quality and heat are top notch
