Introducing the IconX Heated Core Line

The IconX Heated Core line is designed for those who demand the ultimate warmth and comfort during their hunting excursions. The secret behind this revolutionary line lies in its battery-powered heat technology, which provides exceptional insulation without adding bulk. Compatible with various pieces of apparel, the Heated Core line is perfect for hunters who need to stay warm in the most extreme conditions.

Heated Core Vest

IconX Heated Core Vest

The Vest is the collection’s signature item that enjoys the greatest recognition in the series. With that being said, it shares many of its characteristics with other products in the line. Maybe it has to do with the vest’s lightweight design: the lack of sleeves makes this garment a preferable choice for layers, as it feels less bulky than its long-sleeve relative. But let’s delve into the reviewing part to see what a Heated Core Vest has to offer.

Distinctive Features

Battery-powered heat technology: The vest is equipped with a rechargeable 7.4V Lithium-ion battery that powers undetectable carbon fiber heating elements across the chest, kidneys, and base of the neck. This ensures constant and efficient heat distribution where your body needs it most.

Three heat settings: The vest offers three different heat settings (low, medium, and high) to provide customizable comfort. An easy-to-access LED heat level selection button allows you to adjust the temperature according to your preference and the conditions you face.

Lightweight and comfortable design: The IconX Heated Core Vest is designed to be worn directly against the skin or with a thin layer underneath. Its lightweight material and slim fit ensure that it won’t impede your movement or add unnecessary bulk to your outfit.

Versatile use: The vest is suitable for a wide variety of cold weather activities, including hunting, fishing, hiking, and even attending outdoor sports events. It can be worn against the skin or over another.

Odor Control: The garment incorporates SilverStrike antimicrobial technology that protects textiles against odors. That’s helpful in numerous ways: the sweat odor won’t be a problem, and hunters will benefit from the smell not reaching animals. 


Why would you want to opt for this vest? All the garments from the IconX series deliver consistent warmth throughout your core, ensuring optimal heat distribution and keeping you comfortable in cold conditions. The vest is suitable for a variety of weather conditions thanks to its adjustable heating system. With three heat settings to choose from, you have complete control over the temperature level. The vest’s slim design allows for easy layering and total freedom of movement, making it an ideal addition to any cold-weather wardrobe.


There isn’t much to complain about, really. The vest excels at doing what it is designed to do. Putting the garment under close scrutiny, there is one thing that might be inconvenient. Although the battery provides adequate warmth for most situations, some users may find that the battery life could be longer for extended outings. The battery lasts for 2 hours on high heat and 3 hours on medium heat settings, which may seem lacking to some users.

Heated Core Shirt

IconX Heated Core L/S Shirt

The long-sleeved sibling of the Heated Core Vest, the IconX L/S Shirt brings sleeves into the equation. To say this element drastically changes the garment’s functionality would be erroneous. The core remained the same, and so did the placement of heating elements. However, since the pieces of clothing share the price, it really comes down to personal preference. The Heated Core L/S Shirt might be more suitable for wearing as a standalone garment or wearing it under other items of clothing. 

Distinctive Features:

Next-to-Skin Warmth: The IconX Heated Core L/S Shirt is designed to provide warmth right where you need it most – close to your skin. Featuring low-profile carbon-fiber heating elements, this shirt efficiently provides maximum heat output without adding bulk.

Strategic Heat Zones: The shirt boasts strategically placed heat zones in the chest, kidneys, and base of the neck, ensuring that your critical areas stay warm.

Seamless Construction: With a seamless design, the IconX Heated Core L/S Shirt adds to your comfort by reducing friction against your skin.

Rechargeable Battery: The shirt comes with a rechargeable 7.4V lithium-ion battery and a wall charger, so you never have to worry about running out of power during your outdoor adventures. Plus, the USB outlet on the battery can even be used to charge your devices in the field.

Three Adjustable Heat Settings: Customize your level of warmth with the easy-to-access LED heat level selection button, which allows you to choose from three different heat settings.

Athletic Fit: The shirt’s athletic fit ensures easy layering, allowing you to wear additional clothing on top as needed.

Odor Control: Unlike the vest, the Heated Core Shirt is treated with Polygiene Odor Control and Odor Crunch. The technology is different, though the result is very similar: an odorless outdoor experience. 


The IconX L/S Shirt is perfect for a variety of outdoor activities, such as hunting, fishing, hiking, or attending cold sports events. Since the shirt provides ample warmth on its own, you won’t need to wear as many bulky layers, so your freedom of movement won’t be hampered one bit. There isn’t much to say that could complement the pros listed for the Heated Core Vest. 


There isn’t much to complain about in terms of functionality. A few customers have mentioned that sizing can be a bit tricky, suggesting that it might be a good idea to size down to ensure the heating elements are close to the skin.

Heated Core Pants

IconX Heated Core Pant

Finding a top is half the deal. The heat escapes our body through all parts exposed, so we should cover as many of them as possible if we want to retain warmth. That’s where IconX Heated Core Pant kicks in! It’s hard to find a better base layer bottom than these pants, for they combine the best of the two worlds.  

Distinctive Features:

Long story short, the Heated Core Pant boasts the same features as a vest and a shirt. You can expect the same degree of next-to-skin warmth, the same athletic comfortable fit, and the same odorless performance. The placement of heating elements, though obviously different from tops, is equally strategic: lower back and tops of thighs. There are three standard heat levels, and the three-color LED selection button is easily accessible. 


In addition to all the beneficial features mentioned above, Heated Core pants have some other advantageous aspects to them. The fabric wicks away moisture, so you don’t need to worry about getting sweaty. Thanks to their sturdy composition, these pants offer tangible muscle support in 6 key areas. All things combined, IconX Heated Core pants make for an indispensable base layer garment.


The cons are not numerous. The pants could benefit from additional heating elements in the knee area. The battery locations of pants and tops may overlap. That doesn’t create any major inconveniences, but you may feel them stacking on each other. 

IconX Heated Core Replacement Battery

Garments aren’t the only elements of the Heated Core lineup. Say, the battery got broken and you need it replaced. The IconX Heated Core Replacement Battery is a must-have component for those who want to make sure the longevity of Heated Core garments isn’t compromised.

IconX Heated Core Vest and Pant Replacement Charger

To charge a battery, you need a battery and a charger. If either of them breaks, the deal’s over. The IconX Heated Core Vest and Pant Replacement Charger makes sure you can keep using your garments for years to come. This charger is designed specifically for use with the IconX Vest and Pant replacement batteries.

As you can see, the IconX Heated Core Collection is a nonpareil heating solution for outdoor enthusiasts of all stripes. Each garment in the series is designed to deliver superior warming while remaining relatively lightweight. Each piece of clothing comes with a battery and a charger but you can get those separately to prepare for accidental breakages. Pnuma came up with an excellent line of base layer clothing that also happens to deliver unparalleled comfort and warmth.


For how long does Heated Core work?

The Heated Core garments work for varying durations depending on the heat level setting chosen. The approximate battery performance is as follows:

  • Low setting: 6.5 hours
  • Medium setting: 3 hours
  • High setting: 2 hours

How long does it take for Pnuma Heated Core to heat up?

The technology takes around 5 minutes to heat up. After you connect the fully charged battery and turn on the device, it will enter the pre-heat mode (indicated by a flashing red light). Once the 5-minute pre-heat period is over, the power button should automatically change to yellow or medium heat setting.

Does Pnuma Heated Core require any special maintenance?

The garments should only be hand washed in cold water with a mild detergent and air dry. The battery should be removed from the pocket prior to washing. The IconX Heated Core gear should never be machine washed or machine dried.
