Designed in France and manufactured in Europe, the NanoShell 160g is the most compact and lightweight warm jacket in the WISE range. Its dual-sided merino/polyamide weave creates a thermal range suited to temperature variations while running. The hollow fibres of merino wool absorb up to 20% of their weight in moisture, generating a thermal barrier warmed by the body. The GuardLite™ side panels, with no coating, maintain a soft and silent feel while providing wind protection. This jacket has been tested on races such as the Tor des Géants and the Barkley.
