Pipers never worked for me, but I loved the early version Hadleys (which later became the Hadley curvy fit). I bought a few SP brand leather strap goods early on and was not at all impressed so I didn’t buy again, not sure if it ever improved because I know some people who seem to like it.
Their clothing never fit me, either! I had Pipers and Hadleys, and one of their sunshirts. The shirt was clingy and the arms were too short, and the breeches were supremely unflattering . However, most other brands that carry a long cut (or just run long) fit me just fine so I’m not starved for options. I think the biggest benefit was their size inclusive line and curvy fit options - not for me but I know plenty of people that finally found riding clothing that fit from SP. That will be a shame to lose.
Their leather goods are that coated stuff from India in varying degrees of “plastic”, depending on the line. I have a few sub-$100 bridles bought in a pinch because I needed a weird size NOW - hey free shipping! However their mid-range stuff wasn’t bad for the price and I feel like their halters were pretty good quality. I DO like my knock-off Professional’s Choice girth from them and my set of rubber reins.
TLDR: the size-inclusive clothing line will be a major loss to the market, but the tack was just easy to throw in the cart if you’re in a pinch. I think they had good knock-offs of simple tack like synthetic girths that I couldn’t find comparable options elsewhere for so that’s a bit of a shame.
I have quite a few of the SP girths as well. They’re cheap and easy to clean. I didn’t fit in the Pipers, but do have a few pair of Hadleys which fit well. I do have their blankets and sheets. Those are staying, right?
I never liked their breeches, but I have several of their sun shirts that I really liked. I also have a few of their lower end bridles. The older ones are really decent for the price but the newest one I have is definitely lesser quality - but it works quite well for a schooling bridle given the $ I spent on it. They were a nice source of inexpensive leather when you needed a different sized bridle but didn’t have the resources to spend a lot on it.
The Hadley Curvy cut is the closest thing I found to the fit of the late, lamented FITS Beka. And when they said that it was a size whatever Long, it was legitimately Long. I hope they did sell the line.
It appears to be that the blankets and other horse clothing items are staying, yes.
I tried to like their sun shirts but they never fit me or kept me cool like the Kerrits Ice Fil, so I kept sending them back.
My experience with Piper breeches was a love/hate relationship. SP kept changing the cut and the fabric. There was the original fit, then the mid-rise, then the high rise, then that weird Evolution fabric and the knitted ones with the super high waist. I got confused and couldn’t remember what fit and what didn’t. At least they were long enough and when I stumbled upon the correct style I wore them a lot.
