For hunts and field movement across changing ground, the LaCrosse Women's Cold Snap II 8" Olive Night 1200G Boots combines breathable Dry-Core waterproof protection, 1200G Thinsulate Ultra insulation with full-grain leather and 900-denier nylon upper. 1200G Thinsulate Ultra insulation helps retain warmth for deep-winter and very cold conditions without unnecessary bulk. Underfoot, the Permafrost outsole helps maintain traction, and the full-grain leather and 900-denier nylon upper construction keeps the boot suited to extended movement in deep-winter and very cold conditions.
