Prestige. They are soft, lasting, flat buckles, half holed, and around $100. I've had mine for six years of heavy wear and they still look great. Wont buy anything else if I need calf leather.
I have amish made leathers on my dressage saddle and they last, don't stretch, half holes, but they are not calf. They are also bulkier, but I personally love them for my dressage saddles. They are about $50/$60 from Bartville and I have had them for over 7 years and they look new. Just looked at the Gary leathers and they look exactly the same.
I am on my phone 90% of the time. Please ignore typos, misplaced lower case letters, and the random word butchered by autocowreck.
If you're looking for lined and inexpensive, I'd recommend SmartPak's house brand ones. I picked up a pair for my dressage saddle a few months ago, and have been very pleasantly surprised by the value. They're not as nice as the Beval lined leathers I have currently on my jump saddle, or the Prestige ones I had before that (and I would highly recommend either of those if you're willing to spend more), but for less than half the price, I'm quite happy with the Smartpak leathers.
I love the Beval flat buckle stirrup leathers. They don't stretch (because they're nylon lined), last forever, and best of all, come in a "short adult" size which means no having to cut down the leathers for me!
I like soft, narrow, nylon lined and, most importantly, 1/2 holes. . . .
That describes my CWD leathers perfectly, the leather is like butter but not so thick that you can't easily adjust them from the saddle. CWD leathers also have those small flat buckles that are so comfortable you don't even feel them under your thigh. I think they are about $170 now, they were a lot less when I bought my saddle.
I will say that my CWD leathers never stretched at all, I kept them on the same hole for the 7 years that I owned my saddle and would never buy anything else now.
I had to buy leathers in a crunch about 5 years ago when I was headed to a show and my leather buckle snapped (HDR Brand). Ran to my local tack shop and picked up a pair of Red Barn leathers, and have been really happy with them. They lie super flat, and haven't stretched that much. The leather is nice a soft, but not too soft, and the holes are a good 1/2 inch apart. Overall I've been happy with them :-)
Another vote for the Prestige leathers! Leather is soft (there was no break in time at all) and nylon lined. Also, they are stamped "made in Italy" and are not made in China like some of the cheaper brands.
