  • Watertight, non-wicking Hypalon roll top closure with stiffener at the top for a better seal
  • Soft and flexible with a slippery finish for easy packing
  • Nearly transparent allowing good visibility of the contents
  • All seams are double stitched and tape sealed
  • Smaller sizes have flat bottoms, others are round
