Layered up or worn as a standalone, the ARGON JACKET provides the warmth you need on cold winter days. The jacket is filled with our new MICROGUARD SUPERLOFT. The synthetic fibre insulation is insensitive to moisture and delivers very good warmth-to-weight performance. This makes the ARGON JACKET a good alternative to a classic down jacket. The windproof and tear resistant STORMLOCK outer fabric shuts out the cold wind and boosts the insulation performance. In really bad weather, you can zip the jacket into a hardshell using the system zip.
