Factor 1 Base Layer Vest Top are designed with a snug, 100% stretch fit, providing the comfort of a second skin and adapting effortlessly to most body shapes. The long-cut design and stretch fabric ensure the vest stays in place, preventing it from riding up during activity and eliminating discomfort or cold spots on your lower back.

Featuring a super-efficient hydrophilic finish, this base layer wicks away perspiration, keeping your skin warm and dry in all conditions.

Ideal for adding core warmth under other base layers or wearing discreetly beneath workwear during commutes, this thermal vest delivers exceptional insulation without adding bulk to your arms.

Please note: These are end of line garments. There may be some slight colour variations where they have been folded, and some may have different versions of our logo, but apart from this these base layers are perfect. We have greatly reduced the price to reflect this.
