Pittard's leather is the same as non treated leather, most people including some in the industry seem to think that the pattern makes the difference, it doesn't. Having sat in their HQ in Yeovil and been shown all the types of leather available treated and untreated with water testing I understand what the treatment does. They cut a pattern in the leather because they can and it shows the difference between it and untreated standard leather.
Most brands want the softest leather in their palms so all the treatment does is allow the use of this as it prolongs the life of whatever leather is treated. You could use untreated leather for palms and change the gloves a lot but the same leather treated will stay softer longer and last better, even a Pro might see the benefit of this.
Sadly a lot of cheaper brands are just getting the pattern copied and claiming to use Pittard's, to me this is a great indicator of a brands worth and I'd avoid them.
