We like the Charter GORE-TEX Bib for its breathability and packability. It's Grundens most breathable bib, thanks to GORE-TEX Paclite Plus, wich is the lightest, most breathable, most packable GORE-TEX waterproofing. The Charter packs down small and stows easily in our boat or tackle bag but delivers big-time waterproof and windproof protection when we need on the water. We like the light-duty construction, which lets us focus on the fish--not the weather--and the lower leg zippers, which let let slip the bibs off and on easily, even when we're wearing boots.
