Factor 1 Base Layer Leggings

Factor 1 Unisex Base Layer Leggings are one of the best lightweight thermal underwear ranges for general outdoor use.

These unisex leggings are manufactured from stretchy tubular 100% polyamide ribbed fabric with a hydrophilic treatment for superior moisture management.

The extra generous waist heights on thee leggings help to prevent lower back exposure and give extra thermal protection to your kidneys. The waist itself is constructed with an internal strong rubber elastic core that is seamed over with Factor 1 fabric for a low profile. The double layered fabric gusset provides added thermal protection around the groin, whilst the ends of the legs have flat ankle seams that help to reduce pressure exerted from walking shoes and ski boots.

These base layers cross over in to anything from, skiing, through to hiking and camping, and can be used in combination with Sub Zeros Factor 2 mid layers for extra warmth in extreme conditions.

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.
