  • 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.

  • The padded portion of the belt is 1" shorter than the listed minimum adjustment. For example a "Medium (30-36 inches)" belt has padding which measures about 29" tip to tip, and has a minimum adjustment circumference of 30". It is the recommended size if your actual measurement is up to 36" however the webbing extends further.

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.

New Belt

You guys did a great job! Order was shipped and delivered in a timely manner and the YouTube video on how to install the replacement belt was great. Thank you for making such a high quality product right here in the US!

This one fit better!

I received the Medium sized belt to replace the Small size I ordered with my pack. I had followed the sizing recommended when I purchased the pack, but noticed that the belt did not extend far enough to adequately cover my hip bones in front. The video about replacing the belt was extremely helpful and I had it changed over in a short time. I really love the quality and ingenuity designed into Zpack equipment!

Replacement Belt

Very happy the Arc Haul is made with interchangeable parts. After a 40 day section hike on the PCT, my previously belt was damaged (wear spot from a off brand water bottle holster I added). Ordered the replacement and quickly repaired my pack. Delivery was rapid and although I ordered the wrong material, customer service worked with me to get it returned and the right part sent out. Very happy with Zpacks products and customer service!

Arc Haul

I love my Zpacks Arc haul. I used it for 1600 miles of the AT last year and continue to use it for my hikes in Australia. One improvement suggestion : Last year on day 2 I thought I broke my shoulder strap but what it ended up being was the small strap had unlooped through the adjusting clips. I eventually had to duct tape the 4 adjusting straps in place repeated ly over my 109 day hike, as they would continually come loose causing the weight distribution to change and giving me a sore back. once I did this my hike & pack was great. Don't get me wrong....Luv this pack.
