Using the lightest weight 75g/m2 PrimaLoft® ACTIVE insulating fabric, the OMM Men’s Core Boxer 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.
