Thick baffles, thin baffles, welded, woven, sewn through: We’ve seen apparel makers use all sorts of tricks to stuff their down coats. But at Outdoor Retailer, Marmot showed us a new one with their new WarmCube technology. Rather than compartmentalizing the down into long, parallel baffles, the utilizes cube-shaped compartments that Marmot says will keep the fill in place better than ever. The idea is to minimize the shifting of fill and trap heat within the grid-like channels between cubes. After trying on the West Rib Parka, the first model to use the tech, we can confirm that the cubes huggged our bodies better than most down jackets we’ve used, trapping warm air close to us even as we moved. To ward off wet weather, an additional synthetic insulating and water resistant layer on the outside.
The West Rib will be available this August.
