Rumpl's first-ever synthetic alternative to down is a breakthrough in insulation technology. Unlike traditional synthetic fills, their 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.
Great blanket. Worth the price, and a great improvement over the standard Rumpl Blanket. Customer service was AMAZING too. There was a minor hiccup, but I was able to get it resolved before my trip.
