Factor 1 Plus Womens Long Sleeve Base Layer Stretch Top

Factor 1 Plus Womens Long Sleeve Base Layer Stretch Tops contour to your bodies shape to provide a snug comfortable fit with extra support.

Manufactured from super soft 95% polyamide yarn with 5% Elastane for added stretch, these close fitting base layer tops utilise body mapping technology to construct innovative seamless body forms, enabling features such as perspiration control mesh zones to be knitted under the bust and and side of the garment.

The only seams present on these tops are on the sleeves and the shoulders. The set-in sleeves provide a much more tailored fit in the armpits, maximising insulation and moisture transportation (wicking). The round neck has been designed so that it stretches when placed over your head, making it especially useful if you have a lot of hair. Body lengths in all our base layer and mid layer designs are long, giving the wearer a decent amount of fabric to tuck in to their trousers. This helps to avoid lower back exposure during activities and when sitting down.

These Sub Zero tops are one of the best lightweight thermal underwear ranges for general outdoor use. The simple design makes them compatible with most sports where you need to keep warm and dry. They cross over in to anything from skiing  through to hiking and camping, and can be used in combination with the Sub Zero Factor 2 thermal mid layer range for extra warmth in extreme conditions.
