I grabbed 3 True fire buckle releases, new in the package, on a flea market, few years back. He wanted 25 a piece. I give him 65 for all three. Pay that for one nowadays. He offered me another, but in Velcro for 10. snatched up that one too for a backup. Prefer the buckle, but hey. Coated with Need foot oil on the back side. Stored in the dark, when the grandchildren are ready.
They all have length adjustment.
