The ultimate in lightweight insulation, Expolite is designed to hold on to core heat with ruthless efficiency, this jacket is all about conserving energy without having to carry extra kilos. The slender diagonal baffles are packed with high-loft ThermoPro synthetic fill to help trap body heat in the same way as natural down. The recycled mini ripstop fabric has an EcoShield DWR finish to repel showers, while odour-control patches help you stay fresh in the active outdoors. Complete with zipped pockets (one passport size with RFID and one that doubles as a handy stow pocket) and adjustable grown-on hood with elasticated binding to the face. A stellar performer.
