We have to remember, the All-Star LUC-Mags are a different animal than their standard LUC siblings – they're oversized, greater volume, and have that reinforcing plate inside of them.
The only manufacturers that make leather-clad pads of any worth are Belgard and Honig's. Wilsons – despite originating as a leather goods company – are crudely made and full of primitive foam and wool as their rendition of "padding". They're like leather-encased sausages. Same goes for MacGregor and Rawlings. Champro is even worse.
All-Star does make leather pads rather well, but the simple LMX pads don't have enough volume for us, nor include the reinforcing plate. Force3 can't be included in this discussion (yet, @JimKirk ) because their pads are designed for use on the dual-framed Defender masks only. That's a shame, because other than All-Star in the LUC-Mag pad, no one has placed any advanced materials into a leather-clad mask pad. Force3 actually places a laminate of Kevlar, Memory Foam, and EVA foam inside!
With that said, Belgard makes an exceptionally well-designed pad. They are the only ones I've ever seen that not only use premium leather, but also arrange the padding into segments, complete with chin relief. Sure, these features drive the price up, but the primary reason these pads cost so much is the import tax / fees! Why? Because it threatens Wilson's (and other manufacturers') grip on the market! If you can't beat them (on quality), invoke a trade law or regulation, and keep 'em out of your territory! Even if you have moved all your production out of the USA and have it done nearby in low-cost China!!
Honig's is, perhaps, the next best thing. Their leather is supple, and not only do they cut the pads to more accommodating shape, but they also have padding volume inside that creates that all-important standoff distance.
True, except one lone catch – the stuff isn't made in the USA. It's made by USA-origin companies having all their products made in China, and then shipped over for maximum profit.
