XS Scuba Pony Pac Harness

FGSS lists the XS Scuba Pony Pac Harness here as an Amazon-affiliate pick from XS Scuba. Fits 13, 19, 30 or 40 cu ft pony cylinders with 4.0-5.4in diameters. Two trim pockets with quick-release tabs, each holding up to 5 lbs. Waist sizing: Small 25-35in, Regular 30-50in, X-Large 45-55in. This is one of the few harness listings in this batch with genuinely published waist-size ranges -- worth measuring your own waist (over whatever exposure protection you'll be wearing) against the Small/Regular/X-Large ranges rather than guessing, since the X-Large option specifically covers up to 55 inches. You'll complete this purchase on Amazon rather than with FGSS. We link to it as an Amazon Associate and earn a commission on qualifying orders, at no added cost to you. Worth a look at FGSS's own Adjustable Harnesses & Backplates for Larger Divers collection too, if that's relevant to what you're after.
