  • Lid handle makes it easy to grab and take with you
  • Wide-mouth opening fits most backcountry water filters and makes it easy to fill with soup or to add ice cubes
  • Tough, food-grade 18/8 stainless steel is BPA free and resistant to bacteria and odors
  • Note: Bottle may not be 100% leakproof when filled with carbonated beverages; keep the bottle upright
