For hunts and field movement across changing ground, the LaCrosse Men's Alpha Agility 17" Brown 1200G Boots combines waterproof coverage, 1200G Thinsulate Ultra insulation with hand-laid natural rubber over a neoprene core. 1200G Thinsulate Ultra insulation helps retain warmth for deep-winter and very cold conditions without unnecessary bulk. Underfoot, the Agility II outsole helps maintain traction, and the hand-laid natural rubber over a neoprene core construction keeps the boot suited to extended movement in deep-winter and very cold conditions.
