This is why my ancient Passier Monoflap (Military II) will be pried from my cold dead hands. Its brilliant for saving my ass, the balance is fantastic and has webbing instead of leather to which the billets are sewn. No stretching, no tearing and if one billet goes then the other isn’t affected.
I just hunted down a Passier dual flap with the help of Saddle Addictions (FB) that has near identical underpinnings (block, block positioning, tree) as my spare and because one horse seems determined to be a hunter. Annett is unbelievable at stalking down specific models if there’s one you need to find.
