Lighweight Insulation for Key Areas

Overview

Using the lightest weight 75g/m2 PrimaLoft® ACTIVE insulating fabric, the Core Boxers is a highly insulating first layer, perfect for harsh conditions and cold overnights.
The PrimaLoft® ACTIVE fabric has great air permeability, allowing for a comfortable and stable climate to be maintained, even during high output. The woven plume is incredibly warm for its weight and with minimal bulk, whilst the PointZero fly cover acts as a wind and moisture barrier; the Core Boxers are well suited to extreme conditions.

Plus, who doesn’t love fluffy pants?

PrimaLoft® ACTIVE blurs the line between wadding insulation and fabric; PrimaLoft® ACTIVE loosely weaves PrimaLoft®’s industry-leading insulating fibres through a fine polyester mesh. The resultant structure is warmer and less than half the weight of a conventional fleece product – Down like performance when dry whilst also still performing when wet.
