A gilet-style puffer jacket is the hybrid that combines core warmth with sleeve freedom. The lightweight construction means it layers efficiently without restricting movement. Gilet-style puffer jackets work over long-sleeved tops without creating bulk at the shoulders and arms. The silhouette is cleaner and simpler than full puffer jackets. Lightweight gilets work year-round as layering pieces in ways that full jackets sometimes do not. The construction combines the warmth of a puffer with the versatility of a gilet. These are the gilet-style lightweight puffer jackets that solve the problem of needing core warmth whilst maintaining full arm mobility.
