Finding riding apparel that fits shouldn't feel impossible. Plus-size equestrians know this struggle well. The industry has started to recognize that riders come in every size, prompting many equestrian suppliers to rethink their approach. But here's the problem: many brands claim to offer inclusive sizing equestrian wear, yet only provide token "extended" options. This makes shopping frustrating for those seeking genuine fit and function.
Here's the truth: exceptional plus size horse riding apparel exists. Leading equestrian outfit manufacturers understand something important: performance, comfort, and style aren't luxuries reserved for certain sizes. They are necessities for all riders. Whether you are looking for ready-to-wear gear or exploring custom equestrian outfit options, the market is shifting.
We've done the legwork and saddle time to find eight brands worth your money. We have analyzed everything from everyday breeches to high-end custom equestrian clothing that protects your comfort and confidence. This guide cuts through the marketing noise, highlighting top equestrian clothing manufacturers that ship to or operate within the USA.
Fuller Fillies: Best for Wide Calf Fit and Affordability
Fuller Fillies built their reputation on one simple promise: boots that zip up the first time. No struggling. No frustration. Just boots that fit athletic and wide calves without compromise. As specialized equestrian manufacturers, they recognized a gap in the market that standard brands ignored.
Their field boots run significantly less than custom options from European brands. You'd spend double or triple elsewhere for similar specs. Most riders can afford two or three pairs of Fuller Fillies for the price of one pair of custom equestrian apparel from luxury competitors.
The sizing gets specific. You'll find Wide and Extra Wide calf options across three heights: Standard, Tall, and Short. One rider shared her experience with size 9 UK/11 US in Extra Wide Calf. After losing weight, she could fit her entire arm inside the boot shaft. That's how generous the calf space runs. If you fall between sizes, the advice from most equestrian suppliers is to size up for comfort.
The construction earns the loyalty. Thick leather forms the base while stretchy elastic gussets provide flex without sacrificing structure. The zippers act as a testament to the quality control of these equestrian clothing manufacturers, surviving falls and heavy barn work. The grippy sole grabs stirrups right away, meaning no break-in period is required.
SmartPak reviews tell the real story: 4.8 out of 5 stars. Riders with large calves rate these boots highly because they zip up with ease where other "Extra Wide" options still pinch. Wide-calf riders tired of settling get comfort and affordability here.
Kerrits: Technical Performance for Extended Sizes
Kerrits solves extended sizes like an engineering challenge. Their Microcord Bootcut Extended Knee Patch Tights don't just go bigger; they stick to the principles of high-performance custom equestrian clothing design re-engineered for real bodies.
The fabric speaks first. 88% Nylon and 12% Lycra create mid-weight compression that fights muscle fatigue. This isn't shapewear; it is technical gear. The 4-way stretch, a standard for top-tier equestrian outfit manufacturers, moves with your posting trot and bounces back after washing.
The GripStretch™ Suede knee patch runs longer than standard versions. This extra coverage helps your thighs sit better in the saddle, proving that the designers understand the biomechanics of plus-size riding. You get secure contact without struggling with half chaps.
Kerrits stocks full and knee patch options across 1X and 2X. Their tops run through XL, 1X, and 2X. You're not stuck with one "extended" piece. You can build a complete wardrobe that performs as hard as you ride, thanks to one of the most consistent equestrian manufacturers in the game.
RunEquestrian: Premier B2B Manufacturing Partner
RunEquestrian distinguishes itself by not selling directly to riders. Instead, they operate as a powerhouse equestrian clothing factory, building the gear behind many famous brands. Since 2009, their ISO-certified facility in China has been the engine room for plus size riding helmets and large size horse riding pants, shipping over 500,000 pieces annually.
Their comprehensive OEM/ODM services make them stand out. Founder Michael Zhang still tests samples himself, ensuring that every piece of wholesale equestrian clothing meets rider standards. Wang, their fabric specialist, has created 50+ materials specifically for riding, wicking sweat 30% better than standard polyester. This level of material science is what you expect from a top equestrian clothing manufacturer.
Speed and precision set them apart. Samples arrive in 7 days, and bulk orders of private label equestrian clothing ship in 20 days. Compare their 98% on-time delivery to the 75% industry standard. Startups can launch comfortable riding wear for plus size lines without huge upfront costs, starting with just 100 pieces. This accessibility allows smaller brands to access high-end custom equestrian clothing typically reserved for major labels.
The consulting team includes experts with decades of experience in luxury retail. They don't just sew; they help with business plans for market entry. If you lack a tech pack, their design team handles it. For brands looking to expand their full figured riding clothes line, partnering with a capable equestrian clothing manufacturer like RunEquestrian ensures quality without the overhead of building your own factory.
Irideon: Modern Designs with Wide Retail Availability
Walk into most tack shops across America, and you'll spot Irideon. As one of the most accessible equestrian suppliers, their wide retail network means you don't have to wait weeks for shipping. You can try these on today.
The Irideon Ladies' Camber Knee-Patch Breech shows what they do best. Traditional front zipper meets modern contrast stitching. The real innovation lies in the Horsehead tread silicone grip. This pattern works, grabbing your saddle during transitions without that sticky, stuck-in-place sensation cheap grip gives you. It's the kind of detail usually found in custom equestrian outfit designs, but available off the rack.
Dover stocks these breeches because riders buy them, wear them, and come back for more. The sizing consistency is a hallmark of reliable equestrian manufacturers. If you buy a size 12 this year, next year's 12 fits the same way. The styling remains subtle—contrast stitching adds interest without crossing into costume territory.
Ariat: Versatile English/Western Gear Up to XXXL
Ariat ships gear in 4XL. Not just casual tees, but performance show coats, breeches, and boots. They build for both English and Western disciplines, applying the same rigor to extended sizing as they do to their standard lines, proving to be a truly inclusive equestrian clothing manufacturer.
The show coat range runs 36R through 46L. That's XXXL territory. Long versions add 1.5 inches to the body length, and sleeves get an extra inch. These coats button without pulling, a common failure point in poorly designed wholesale equestrian clothing. Half chaps also tell a story of inclusion, with XLR measurements accommodating 17.5-inch calves.
Boots get real attention for fit. The Windermere II tall boot comes in Regular and Full Calf options, with the Full Calf jumping to 18.25 inches. Unlike some equestrian outfit manufacturers that simply widen the shaft, Ariat scales the height and footbed proportionally. Women's workwear scales to XXXL with correct proportions, ensuring you aren't stuck with "bigger everywhere" sizing that ignores body shape.
Royal Highness Equestrian: Curve-Specific RH+ Line
Royal Highness Equestrian created their RH+ Line after listening to hundreds of curvy riders who felt invisible to standard equestrian suppliers. This collection doesn't apologize for bodies; it celebrates them. Every piece functions like custom equestrian apparel, built for curves from the start.
The RH Plus Full Seat Mid Rise Breech uses 94% Cotton/6% Lycra for breathable four-way stretch. The modified rise sits where real bodies bend, preventing waistband gapping. The 2025 Foil Show Shirt brings feminine lines to competition wear with princess seams that follow natural curves rather than fighting them. It is a prime example of how equestrian clothing manufacturers should approach design.
Boots and half chaps get genuine leather construction. The Plier Panel design flexes with your ankle, offering the feel of high-end custom equestrian clothing at a ready-to-wear price point. Whether it's the Easy Care Dressage Show Coat or their durable western shirts, the RH+ line proves that technically sound gear is possible for every body type.
R.J. Classics: Premium Show Apparel Up to 24W
R.J. Classics puts real engineering into showring style. Their Ladies Harmony Plus Mesh Show Coat goes up to women's size 24W, a rarity in competition wear. Other custom equestrian clothing brands often struggle to maintain structure in larger sizes, but R.J. Classics uses Italian Jersey to provide structure without stiffness.
Their 37.5® thermoregulation technology makes a tangible difference, keeping your core at roughly 99.5°F. This tech, typically found in expensive custom equestrian outfit lines, comes standard here. The Ladies Sofia Plus Show Shirt reaches 2X with UPF 50 protection, ensuring you are shielded during long outdoor shows.
Prices range from $539 to $569, reflecting the premium materials used. Just like the best equestrian manufacturers, they ensure consistent quality—wash the Italian Jersey fifty times, and the tech keeps working. Standard sizing sits next to extended plus options, making R.J. Classics a go-to for inclusive, premium show apparel.
Romfh: Inclusive Sizing Champion (22-44)
Romfh's Curve Fit breeches solve the waist gap problem that curvy riders face. The brand covers sizes 24 through 40, effectively acting as valid equestrian suppliers for sizes XS through 4X. The secret is in the rise measurements; size 40 reaches a 13.5-inch rise, providing coverage exactly where it is needed.
The fabric blend of 68% Polyester, 22% Cotton, and 10% Elastane features Dura-Dry tech. It acts like the material used in wholesale equestrian clothing designed for heavy athletic use—tough but breathable. Riders consistently rate these breeches highly because they eliminate the back gap without needing a belt to cinch everything tight.
With both regular and long inseam options across all sizes, Romfh ensures the inclusivity promised by modern equestrian outfit manufacturers. You get proper proportions that fix common fit problems, allowing you to focus on your ride rather than pulling up your pants.
Conclusion: Choosing the Right Gear
Finding quality plus size horse riding apparel shouldn't feel like searching for a unicorn. These eight brands prove that inclusive sizing has evolved beyond basic accommodation. Whether you are a rider looking for a single pair of breeches or a shop owner looking for wholesale equestrian clothing, the options are better than ever.
When selecting gear, remember that custom equestrian apparel logic applies even to off-the-rack items. Measure yourself every time. A "2X" from one equestrian clothing manufacturer might differ wildly from another. Look for detailed fit descriptions and size charts that include thigh and upper arm measurements. Brands like Romfh and Fuller Fillies understand non-proportional grading, adding space where bodies actually expand.
For business owners reading this, the demand for private label equestrian clothing in extended sizes is growing. Partnering with a skilled equestrian clothing factory like RunEquestrian can help you tap into this market with OEM/ODM services. The future of equestrian sport is inclusive, and thanks to these dedicated equestrian manufacturers and high-end custom equestrian clothing designers, every rider can now enter the ring with confidence.
