Heat X is Style Union’s winterwear line made for keeping warm and being at ease for the entire winter season. This collection focuses on smart insulation, gently soft and light fabric, and lightweight design. You can stay warm and cozy for the entire winter, and you won't feel bulky and restricted.

Imagine your most comfortable blanket, then wear it outdoors on a chill day.

How Heat X Works

Heat X is made with Volcanic Rock Fibre, a smart material that helps trap body heat and release it evenly, keeping you warm without feeling heavy.

Instead of one bulky winter jacket for every situation, Heat X offers different warmth levels designed for your climate, daily routine, and comfort needs. Each level balances heat retention, breathability, and easy movement, so you stay warm, flexible, and comfortable all day.
