Is the guide light MT belt a different fit?
I am a 34-35 waist and the belt was on the small side on my medium Beartooth. I just ordered a large belt from MR. I plan on keeping both to have some flexibility with my current body shape and clothing needs...
Between my (oldest to newest) 3DAP/ Rush/ Coulee 40 all were Medium and fit me well for my 32 waist. All pants are 32
When I got the Guidelight I had to downsize to Small to prevent slippage.
When I got fitted by MR salesperson for Guidelight MT, he recommended the Medium for true fit. I've only loaded my pack maybe 25 lbs and so far happy with the Medium belt on Guidelight MT frame
