The Rocky Stratum Stretch Insulated Bib is a new take on a classic hunting piece. To the touch this ultra-thin and light-weight bib seems like little more than a pair of overalls, however when you consider the 60 grams of Primaloft insulation the story begins to unfold. Primaloft is a superior insulation providing excellent warmth at a fraction of the weight. Surrounded by a soft 4-way stretch fabric, printed in Rocky's own Venator camo, and you have a great bib for the cool opening or closing hours of your hunt. As the season wears on this is a great piece for layering with our Parka (HW00155) or the Waterproof Pant (HW00208) in the most brutal conditions. Regardless of the weather know that you'll be hidden from the deer's sense of smell with Rocky ScentIQ Atomic technology eliminating human scent at the microbial level. Choose the Rocky Stratum Stretch Insulated Bib for the ultimate in comfort, versatility, and packable insulation.
