What is Heat Boost?

Published on Jan 28th 2025 by Nate Sellers

One of the age-old questions when it comes to making your garments warmer is how do you do it without adding bulk to the garment? Particularly when the mercury drops below zero, you really want to have a garment that allows you to still bow hunt and firearm hunt, climb into your saddle or tree stand without adding extra bulk, weighing you down, or tangling you up inside the garment.

Our answer to that problem is Heat Boost graphene technology. We took graphene yarn and knitted it right into our high pile sherpa garments. You can find this technology inside of our Grayling hoodieSaskatoon pants, vest, and jacket, and the Matterhorn jacket and bibs. Heat Boost is a full lineup of insulated hunting jackets, pants, and bibs for both men and women. With options from form fitting ultra quiet hoodies to fully windproof and waterproof jackets and bibs – Heat Boost has you covered. Anytime you see the Huntworth Heat Boost logo on the sleeve or the bottom hem of the jacket, you know that you’re in for superior warmth.

When we use graphene technology, it allows us to retain our body heat longer. It’s absorbed into the graphene that’s knitted inside of the sherpa. This means it retains the heat and reflects it back to you. Therefore, we do not have to add a whole bunch of extra filler such as polyfill or feather down to make this jacket warmer. This allows it to stay thinner, which means you stay more flexible while still staying warmer than traditional fabrics.

Heat Boost works a lot like a pot of hot water on the stove: once you to get it to boil it’s definitely hot. But then it remains hot long after it's done boiling - that's what Heat Boost is inside of your jacket, pants, or bibs. Once you add your body heat to the graphene sherpa on the inside, it retains the heat longer. With a windproof and/or waterproof film on the Saskatoon and Matterhorn garments, it keeps that cold air from penetrating into the Heat Boost, making sure it stays warmer longer and keeps you on stand.
