Factor 2 Womens Long Sleeve Zip Neck Mid Layer Top

Factor 2 Womens Long Sleeve Zip Neck Mid Layer Tops blend of innovative materials and functional design, makes it the ultimate companion for outdoor adventures. 

Crafted from soft virgin polyester, this single-sided microfleece is enhanced with a hydrophilic treatment to improve moisture management and reduce drying times. The brushed inner surface effectively traps body heat, providing excellent insulation against the cold, while the smooth outer layer allows for seamless layering. With Spandex woven into the fabric, these mid-layers offer exceptional stretch, contouring comfortably to your body’s shape without restriction, whether worn directly against the skin or layered over Factor 1 Plus base layers.

The stand-up, double-thickness turtle neck incorporates an 18cm (7-inch) zip with a reverse wind baffle for added protection and ventilation options. Known for its long body lengths and drop-back hem, this design prevents cold spots on the lower back during movement or whilst seated. Set-in sleeves and contoured body panels ensure a tailored fit, with strategically placed stretch zones around the bust and hips for added comfort. Low-profile cuffs with thumbholes keep sleeves in place when layering and provide extra warmth for your hands in chilly conditions.

Whether you're hiking, skiing, or running errands on a chilly day, this top delivers on warmth, comfort, and style.

SIZING GUIDE
There are no standard sizes for clothing, which is why each brand has their own unique cut and fit. Please do not presume you are the same size between brands for a similar product. If you have a base layer that fits correctly, then use it as a template for these measurements.  

HOW TO MEASURE
Chest* - Measure the full circumference of your chest just below the armpits, above your breasts if possible.
Hem - Measure the full circumference at the top of your hips
Back Drop - Measure from the back of your neck to the base of your spine. Due to the contoured drop back, this will be 5cm longer than the front. 
Arm Length* - Measure from the end of your shoulder to your wrist

*Chest: The in-built stretch of the fabric will accommodate busts of varying sizes, which is why we ask you to measure above them. For fuller busts, you may wish to wear the next size up, but please be aware this may lead to a baggier fit elsewhere.  

*Arm Length: This measurement is only applicable for long sleeves. Short sleeve versions of these mid layer tops finish just above the elbow, whilst the sleeveless version ends at the shoulder joint. 

MID LAYER FIT
Our mid layers will contour to most body shapes when worn thanks to the fabrics in-built stretch. You should wear them close fitting but not so they are restrictive. Wearing baggy or ill fitting mid layers will lead to the loss of heat and a reduction in their wicking properties.

These mid layers are designed to be worn over the top of our Factor 1 Plus base layers but they can be worn directly next to the skin if required. Sizes for both Sub Zero base layers and mid layers are comparable - so if you wear a Factor 1 plus base layer in large, then you should require a Sub Zero Factor 2 mid layer in the same size and vice versa. However, this may not work out for everybody so please consult the size chart below. 

Please be aware that these measurements are taken from the garments unstretched, apart from the 'TO FIT CHEST' column, that indicates the range of fit. They are applicable to our long sleeve mid layers in round neck and zip turtle styles, short sleeve round neck style, and sleeveless style top as the bodies are based on the same pattern.

This is also the case for the Factor 2 Plus range - it is a thicker fabric but the construction utilises the same patterns as the Factor 2 mid layer range, hence the sizing is the same. 

The table below shows the garment measurements for our Factor 2 Mid layers. There is a tolerance of +/- 5mm.
