The Cetus Lite is our high-performance waterproof jacket built for outstanding breathability (RET <5) using Montane’s new PETRICHOR TECHNOLOGY™ . The 100% recycled nylon outer has a PFC-Free DWR coating and 3-layer durability. This jacket’s 100% waterproof, hydrophilic membrane excels in transporting water vapour and moisture away from your body and out into the air during high-intensity outdoor adventures, while keeping out the wind and rain (20,000mm hydrostatic head). The harder you work, the harder it works to ensure comfortable, efficient movement in the mountains.
