The Grumman Down Jacket has been a staple in our packs since its inception, but we often found that it was just more insulation than we needed for most early season conditions. Enter the Grumman LITE. Ultralight yet packed with 850+ fill HyperDry goose down and a weather-resistant face fabric, the Grumman LITE Down Jacket provides the exact same functionality as the original Grumman but in a minimalist design made for milder conditions.
