  • To measure your belt size use a string or cloth tape measure pulled tight around the spot on your body that you want the belt to ride. Usually this will be near the top of your pelvic bone. The tape measure should be over top of your hiking pants and shirt.

  • Do not rely on your pant size.

  • A medium belt has a minimum circumference of about 30" (76 cm) including the buckle. Each belt has about 15" (38 cm) of webbing for adjustment.

  • Choose a belt with a minimum adjustment a couple inches smaller than your measurement so that you can still tighten it down if you lose a little weight on trail.

To remove the existing belt:

  • The belt is attached directly to a horizontal frame bar. To remove the belt, pull out gently at the center until the frame bar bows enough to pop out of its holster at the left or right. The belt slides off the bar.

To put the new belt on:

  • The pack belt attachment has two pockets (left and right) and two loops towards the middle (left and right).  

  • Slide the bar through the right loop on the pack. Then through the back of the belt. Then through the left loop on the pack, and into the left pocket on the pack.  

  • Make sure the bar is all the way into the left pocket.  

  • Pull out gently on the center of the belt to flex it until the right side of the bar pops into the right pocket on the pack.

  • Replacing the belt can be a bit tricky and it is not something you would want to do frequently. The spare belt includes a spare frame bar.

Great belt and service!

Needed to upsize the belt due to lack of accounting for the space taken by the additional lumbar pad I chose to include in my pack build. The Zpacks Team made the switch easy, and this new belt is a perfect fit!

Needed a smaller waist belt

I lost weight during my AT hike. So I ordered a smaller hip belt. The belt arrived a few days later. Unfortunately off the trail now due to covid 19 concerns. Looking forward to hiking with the new belt more soon
