Most people think of these two as twins… but they are more like cousins. “Merino”is the name most people recognize when they think of premium wool. It is known for being fine, soft, and comfortable. Rambouillet carries many of those same qualities, but it has its own story and its own strengths. Rambouillet sheep came from Spanish Merino bloodlines, but over time they became something distinct. The breed was developed in France in 1786, after King Louis XVI purchased more than 300 Spanish Merino sheep from King Charles III of Spain. Those sheep were placed at the Bergerie Royale in Rambouillet, France, where they were carefully bred and developed over generations. The goal was not simply to keep the Merino sheep exactly as they were. The goal was to build on the qualities that made Merino wool valuable while creating sheep with more size, resilience, and wool that could hold up. That is where Rambouillet begins to separate itself. Like Merino, Rambouillet wool is also soft, but it is especially valued for its strength, density, and ability to recover. These are the quality’s we look for in our saddle pads. It has to manage heat, move moisture, handle pressure, and keep its shape through repeated use. By the 19th century, Rambouillet sheep had become much larger than their Spanish Merino ancestors. Ewes could reach up to 200 pounds, while rams could reach up to 300 pounds. Their wool also developed a longer staple length, often exceeding three inches. That added size and fibre length helped create wool with more density, durability, and recovery. Merino may be the wool most people know first, but Rambouillet is the wool worth understanding when it comes to your saddle pads.

First, we have to understand a few things. Wool is a natural fibre, grown by sheep. “F10” is a grade on a scale that is used to determine the quality of that wool. Long before the grading system starts, there are conscious decisions being made about which ram would complement each ewe in developing the best wool outcome. Wool quality begins in the flock, through selective breeding and generations of knowledge. This is where HAPPY VALLEY FARMS has excelled.  A high-quality wool clip is the result of intention. The strength, softness, CPI and consistency of the fibre are considered before the wool is ever shorn. From there, the wool is harvested, processed, and graded based on its composition and performance qualities. This is where F10 becomes important. F10 is recognized as one of the higher grades of wool felt. It is valued for its high virgin wool content, silky feel like on ours pads, and ability to maintain structure under pressure. In saddle pad construction, these qualities matter because we are constantly looking for a pad to outperform other PSI ratings and bounce back to its intended shape. A quality wool felt pad must be able to manage moisture, regulate heat, and hold its shape over time. Lower-grade felt or materials with a higher amount of reworked wool may appear similar to the untrained eye, but it often does not perform the same under repeated use. When it doesn’t you will notice these lower rated wools starts to develop  “hard spots”. The difference is not only in how the wool feels in the hand, but in how it behaves on your horses back.  When we talk about F10 wool we are talking about a grade, but we are also talking about our standards that begin in the pasture, make its way to the shearing shed then to your horses back.
