Warmth doesn’t have to come at the price of added weight. Unlike ordinary fleece, Peloton 97's Karuishi Fleece uses a 2-layer knit structure with a brushed-fleece interior for more loft and better insulating properties, while the exterior is tightly woven for higher abrasion resistance. It features quiet ultra-fine polyester fibers for an ultra-soft feel with a hydrophobic nature that wicks moisture away from your skin.
