I'm using use Crow belts
Crow Enterprizes Home
Well made (I've been a master parachute rigger for almost 40 years so I've had a lot of experience with these types of units). My belts have been custom modified for my ERA and I've had them re-webbed twice. Crow doesn't have any problem following my modified design or certifying the re-webbed belts.
Reasonable prices with a large selection of full sets or individual belts.
