The bitter cold has a way of creeping into any crack or crevice it can find. Eliminating those entry points was our goal with the Silens Bibs. Cover those cracks in ultra-warm, uber-quiet Badlands Silens fleece and extend your cold-weather sits for as long as it takes. Filled with 100-gram PrimaLoft® insulation and packed with user-friendly features, the Silens Bibs are both silent and deadly.
