Many new synthetic materials use the "hollow fiber" method, which makes the sleeping bags light and provide good compression when packed while providing excellent warmth. The long fibers found in synthetic filled sleeping bags are more stable and less prone to slippage during use. On the other hand, short fibers, both down and synthetic, can shift during use, influencing the sleeping bag's attic and inviting cold air.
