Blaklader XWARM Half Zip Undershirt

Looking for reliable thermal underwear that actually keeps you warm during those bone-chilling days? This thermal shirt from Blaklader combines smart engineering with real-world comfort. The XWARM undershirt is specifically designed for extreme cold conditions, featuring a clever two-layer system that moves moisture away from your skin whilst keeping warmth locked in. The inner cable-knit polypropylene layer works hard to pull perspiration outward, where the merino wool outer layer absorbs and manages it effectively. You get breathable comfort without the chill, making it ideal for outdoor work, static positions in harsh weather, or any job where temperatures drop significantly. With an extended back panel for added coverage and ribbed cuffs that seal in warmth, this undershirt delivers the performance you'd expect from a premium undergarment. Designed for temperatures between minus 20 and minus 35 degrees Celsius, it's built to handle serious cold.

Key Features

• 70% merino wool, 30% polypropylene construction for superior warmth
• Moisture-regulating properties keep you dry during physical work
• Half zip design with high collar for easy temperature adjustment
• Extended back panel provides additional lower back coverage
• Terry cloth interior adds comfort against skin

Recommendations from our Unishore Expert

When you're working in extreme cold, comfort matters just as much as safety. This undershirt excels because it actually understands how your body works. The inner layer actively pulls sweat away before it can chill you, whilst the outer layer absorbs that moisture so it won't freeze against your skin. That's genuinely useful during long stationary work in biting cold.

The half zip is a smart touch. Rather than being stuck with an all-or-nothing approach, you can adjust ventilation on the fly without stripping off completely. The high collar sits snug around your neck to prevent cold air from creeping in, and that extended back panel means you stay covered even when you're bending or stretching.

The ribbed cuffs at the wrists and hem work as a barrier against the cold, sealing in warmth where it matters most. If you're regularly exposed to extreme winter conditions, this represents solid value for the level of protection and comfort you receive.
