Rumpl’s Nanoloft filling is a synthetic alternative to down and is a breakthrough in insulation technology. Unlike traditional synthetic fills, Rumpl's 100% post-consumer recycled NanoLoft® insulation is made up of tiny circular clusters of fiber that mimic the properties of down clusters. This technology traps warmth inside small pockets of air to efficiently preserve heat, regardless of conditions.
