The Mountain Hardwear Women's Compressor PL Jacket is an updated version of the Mountain Hardwear classic. Just like the original, the Compressor PL Jacket is insulated with Primaloft insulation and is constructed with Lunar Ripstop nylon, which will be superlight and even water-resistant. One of the updates is that the Primaloft insulation is now Primaloft Eco, which contains 50% recycled polyester. Although this jacket is so light weight at only 14 ounces, it will provide amazing insulation and is a perfect layering piece for cold days of skiing or climbing.
