  • Directions to Attach Hip Belt
  • Available options:

  • 1” Webbing Hip Belt is made with 1" wide Nylon webbing and comes with (2) Slik Clips and a 1" dual adjustable male and female buckles.
  • Removable Padded Hip Belt attaches with 1 Slik Clip on each side of the pack to the 1” webbing loops and increases the overall carry weight of the pack by 5-7 lbs. 

  • Directions for use:
     To attach the 1” Webbing Hip Belt or Removable Padded Hip Belt, open the Slik Clips (if closed) and slide them with the hook facing up and sliding up into the 1” webbing loop located at the lower end of the shoulder strap on the shoulder wing (the male side buckle should always be on your right hand side). To close the Slik Clip, put pressure on the center of the hook and clasp it until it locks into place. To open and remove the belt, simply push on the center of the hook end and pull up on the end where the clip locks in place, this makes opening the Slik Clip much easier.
