Redheat Pro Grid Thermal Top
The Kombi RedHEAT Pro Grid Thermal Top is a fitted, long-sleeve base layer made from a 200 g polyester-blend knit, intended for low-to-moderate-intensity winter activities. The fabric uses MaeTrX RedHEAT microcrystal technology to capture, store and redistribute body heat, and also provides UV 50+ protection, quick drying and antimicrobial odour neutralization; a ventilated grid construction (RedHEAT PRO Grid) wicks moisture and regulates body temperature. It features four-way stretch, flat seams and a stand-up collar, and is shown in black with an orange KOMBI logo at the hem and upper center back.

A thermal baselayer for low- to moderate-intensity winter activity
Kombi's Redheat Pro Grid Thermal Top is made as a baselayer for active winter days, with a thick 200 g polyester-blend knit designed for low-to-moderate-intensity activities. Four-way stretch allows greater freedom of movement, and flat seams are described as maximizing comfort. Kombi describes it as a perfect baselayer for an active winter.[2]
Actively store and retain heat from various sources
The Redheat Pro Grid Thermal Top features MaeTrX RedHEAT™ technology, which captures, stores, and redistributes heat generated by various sources. This technology responds quickly to unconventional heat sources like body heat, the sun, and indoor heating systems. The heat is equally distributed across the entire garment for enhanced warmth.[1,2]
Staying comfortable during active outdoor wear
Kombi markets this thermal top for outdoor activity, with a breathable, ventilated grid construction. Its RedHEAT™ PRO Grid technology is described as wicking away moisture and helping regulate body temperature while you wear it. Note this is the brand's technology description rather than a reported user outcome.[2]
Staying dry on the move
Kombi designed this thermal top's RedHEAT PRO Grid fabric to wick moisture away and regulate body temperature, with a breathable, ventilated grid construction. The fabric is also described as quick drying, so it's aimed at staying comfortable when you heat up during outdoor activity. These performance points come from the product listing, not reported customer experiences.[1,2]
Staying fresh through long days outdoors
This thermal top is designed with anti-microbial odor neutralization built into the fabric, a feature the brand says comes from its microporous RedHEAT fiber structure. That makes it a fit for active outdoor wear where sweat and repeated use can leave base layers smelling less than fresh. The same fabric is also described as quick drying, which supports wear during high-output activities.[1,2]
Sun protection on the trail
Wear this thermal top when you're hiking, skiing or spending long hours outside and want shielding from the sun. The fabric offers UV 50+ protection, so it can serve as a base layer that also helps cover your skin during bright, sunny days.[2]
