Durable, rugged, comfortable…see why Simms® Challenger Waterproof Insulated Fishing Bibs are a popular choice for anglers, especially for ice fishing. It starts with heavy-duty Toray 2-layer fabric—rugged on the outside, lined on the inside—that provides breathable waterproof protection. Even the front zipper blocks water from getting in. PrimaLoft® Silver Insulation provides bulk-free warmth all throughout the Bobs. The exterior is designed with abrasion-resistant panels and drop-in plier pocket for functional fishing. And adjustable elastic suspenders equip you with the perfect fit. So you fish comfortably right through the storm or on frozen lake.
