Factor 2 Plus Womens Long Sleeve Mid Layer Tops are designed for active women who enjoy the outdoors, combining innovative fabric technology with a stylish, functional fit. 

Building on Sub Zero’s award-winning mid-layer fabric, the Factor 2 Plus takes warmth and performance to the next level. Manufactured with additional yarn, it creates a thicker single-sided microfleece that traps even more body heat, offering a 20% increase in warmth compared to its predecessor. The fabric retains its hydrophilic treatment, enhancing moisture wicking and reducing drying time. With the same amount of Spandex woven into the material, these mid-layers offer exceptional stretch and flexibility, contouring to your body without restricting movement—whether worn as a standalone layer or over a .

Designed with practicality and comfort in mind, the low-profile round neck stretches easily for hassle-free wear, even for those with long hair. The extended body length and dropped back prevent cold spots on the lower back during activity or while sitting. Tailored for a snug yet comfortable fit, the set-in sleeves and contoured panels adapt to the upper body, with strategically placed stretch zones around the bust and hips. Thumbholes in the low-profile cuffs keep sleeves in place when layering and add extra warmth by protecting your hands from the cold.

Elevate your outdoor gear with the Factor 2 Plus Women's Long Sleeve Mid Layer Top. Whether you’re hiking, skiing, or enjoying winter walks, this thermal mid-layer ensures you stay cosy in the cold.
