It's no secret that layering helps keep us warm, but it's easy to end up feeling a little overstuffed in our effort to layer up. Our men's Midstream Insulated Pull-Over features PrimaLoft® Gold for the highest warmth-to-weight ratio available with synthetic insulation. The resulting thin profile and lightweight feel of this jacket keep you moving and casting freely, while offering unmatched warmth for its volume. It features a pass-through kangaroo pocket and is finished with a smooth Pertex® face for wind resistance.
